What's the best method to water my Bigleaf magnolia?
You might want to put a garden hose at the plant base to ensure that you're promoting excellent root development. Avoid directly spraying the leaves, and know that the leaves will require more watering if they are outdoors and facing direct sunlight. You can also use bubblers that you can put on to each plant to moisten the roots. Also, use soaker hoses that can cover the entire garden or bed when adding or removing plants to push the roots deeply. Drain any excess water and wait for the soil to dry before watering. Water at ground level to prevent diseases. On a sunny day, you might want to spray the entire bush with water. Whether potted or in-ground, please remember Bigleaf magnolia prefers deep watering over light sprinkling.

What should I do if I water Bigleaf magnolia too much/too little?
An overwatered Bigleaf magnolia can start to have leaves that turn yellow, drop off and wilt. The plant can also look dull and unhealthy, with signs of mushy stems. When they are beginning to show these signs, it's best to adjust your schedule whenever possible.
The wilting can also be a sign of under watering as well. You might see that the leaves begin to turn crispy and dry while the overwatered ones will have soft wilted leaves. Check the soil when it is dry and watering is not enough, give it a full watering in time. Enough water will make the Bigleaf magnolia recover again, but the plant will still appear dry and yellow leaves after a few days due to the damaged root system. Once it return to normal, the leave yellowing will stop .
Always check the moisture levels at the pot when you have the Bigleaf magnolia indoors. Avoid overwatering indoors and see if there are signs of black spots. If these are present, let the soil dry in the pot by giving it a few days of rest from watering.
Overwatering can lead to root rot being present in your plant. If this is the case, you might want to transfer them into a different pot, especially if you see discolored and slimy roots. Always prevent root rot as much as possible, and don't let the soil become too soggy.
You should dig a little deeper when you plant your Bigleaf magnolia outdoors. When you check with your fingers and notice that the soil is too dry, it could mean underwatering. Adequate watering is required to help the plant recover.

How often should I water my Bigleaf magnolia?
The Bigleaf magnolia likes deep and infrequent watering. You would want to soak them in a gallon of water each time, especially when they are planted in pots. The water storage of flower pots is limited and the soil will dry out faster. Watering is required every 3 to 5 days when living in a cold region. Water it early in the morning when the soil is dry, outdoors or indoors. You can also determine if watering is needed by checking the soil inside. When the top 2-3 inches of soil is dry, it is time to give the plant a full watering. During hot days, you may need to check the moisture daily, as the heat can quickly dry out the soil in the pot.
Irrigation of the soil is also required if you have a garden. When you live in a hot climate, you might want to water once a week. Only water when you notice that about 2 to 3 inches of soil become too dry outdoors or indoors. Consider the amount of rainwater on the plant and ensure not to add to it to prevent root rot.You may not need additional watering of the plants if there is a lot of rainfall.Bigleaf magnolia generally grows during spring and fall. When they are outdoors, you need to add mulch about 3 to 4 inches deep to conserve more water.
You need to water the plants more frequently in sandy soil because this type tends to drain faster. However, with the clay one, you need to water this less frequently where you could go for 2-3 days to dry the plant and not develop any root rot. You could mark the date on the calendar whenever you water and when you notice that the leaves are starting to droop. This can mean that you might be a day late.

How much water do I need to give my Bigleaf magnolia?
The Bigleaf magnolia generally needs about a gallon of water each schedule,With the potted plants, you might want to water them deeply until you see that the water is dripping at the bottom of the pot. Then, wait for the soil to dry before watering them again. You can use a water calculator or a moisture meter to determine the amount you've given to your plant in a week. Provide plenty of water, especially in the flowering period, but let the moisture evaporate afterwards to prevent root rot.
If Bigleaf magnolia is planted outdoor with adequate rainfall, it may not need additional watering. When Bigleaf magnolia is young or newly planted, make sure it gets 1-2 inches of rain per week. As Bigleaf magnolia continues to grow, it can survive entirely on rainfall. Only when the weather is too hot, or when there is no rainfall at all for 2-3 weeks, then consider giving Bigleaf magnolia a full watering during the cooler moment of the day to prevent the plant from suffering from high heat damage. Additional watering will be required during persistent dry spells.

Should I adjust the watering frequency for my Bigleaf magnolia according to different seasons or climates?
The Bigleaf magnolia needs outdoors come from rain, with only persistent dry weather requiring watering. Throughout the spring and fall growing seasons, the soil needs to be kept moist but not soggy, and alternating dry and moist soil conditions will allow the Bigleaf magnolia to grow well. Throughout the summer, hot weather can cause water to evaporate too quickly, and if there is a lack of rainfall, you will need to water more frequently and extra to keep it moist.
Usually, the Bigleaf magnolia will need less water during the winter. Since the Bigleaf magnolia will drop their leaves and go dormant, you can put them into a well-draining but moisture-retentive soil mixture like the terracotta to help the water evaporate quicker. Once your Bigleaf magnolia growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Bigleaf magnolia can rely on the fall and winter rains to survive the entire dormant period.
After the spring, you can cultivate your Bigleaf magnolia and encourage it to grow and bloom when the temperature becomes warmer.This plant is not generally a fan of ponding or drought when flowering. You must ensure that the drainage is good at all times, especially during the winter.
When the plant is in a pot, the plant has limited root growth. Keep them well-watered, especially if they are planted in pots during summer. They don't like cold and wet roots, so provide adequate drainage, especially if they are still growing.
It's always best to water your Bigleaf magnolia’s diligently. Get the entire root system into a deep soak at least once or twice a week, depending on the weather. It's best to avoid shallow sprinkles that reach the leaves since they generally encourage the growth of fungi and don't reach deep into the roots. Don't allow the Bigleaf magnolia’s to dry out completely in the fall or winter, even if they are already dormancy.
Don't drown the plants because they generally don't like sitting in water for too long. They can die during winter if the soil does not drain well. Also, apply mulch whenever possible to reduce stress, conserve water, and encourage healthy blooms.

What should I be careful with when I water my Bigleaf magnolia in different seasons, climates, or during different growing periods?
If planting in the ground, Bigleaf magnolia mostly relies on rain. However, if there is no rainfall for 2-3 weeks, you may need to give proper consideration to giving the plants a deep watering. If watering Bigleaf magnolia in summer, you should try to do it in the morning. A large temperature difference between the water temperature and the root system can stress the roots. You need to avoid watering the bushes when it's too hot outside. Start mulching them during the spring when the ground is not too cold.
The age of the plants matter. Lack of water is one of the most common reasons the newly planted ones fail to grow. After they are established, you need to ease off the watering schedule.
Reduce watering them during the fall and winter, especially if they have a water-retaining material in the soil. The dry winds in winter can dry them out, and the newly planted ones can be at risk of drought during windy winter, summer, and fall. Windy seasons mean that there's more watering required. The ones planted in the pot tend to dry out faster, so they need more watering. Once you see that they bloom less, the leaves begin to dry up.
Potted plants are relatively complex to water and fluctuate in frequency. Always be careful that the pot-planted plant don't sit in the water. Avoid putting them in containers with saucers, bowls, and trays. Too much watering in the fall can make the foliage look mottled or yellowish. It's always a good idea to prevent overwatering them regardless of the current climate or season that you might have. During the months when Bigleaf magnolia begins to flower, you might want to increase the watering frequency but give it a rest once they are fully grown.
Give them an adequate amount of water once every 3 to 5 days but don't give them regular schedules. Make sure the soil is dry by sticking your finger in the pot, or use a moisture meter if you're unsure if it's the right time. Too much root rot can cause them to die, so be careful not to overwater or underwater regardless of the climate or season you have in your area.

Why is watering my Bigleaf magnolia important?
Watering the Bigleaf magnolia helps transport the needed nutrients from the soil to the rest of the plant. The moisture will keep this species healthy if you know how much water to give. The watering requirements will depend on the weather in your area and the plant's soil.
The Bigleaf magnolia thrives on moist soil, but they can't generally tolerate waterlogging. Ensure to provide enough mulch when planted on the ground and never fall into the trap of watering too little. They enjoy a full can of watering where the water should be moist at the base when they are planted in a pot to get the best blooms.
If they are grown as foliage, you need to water them up to a depth of 10 to 20 inches so they will continue to grow. If it's raining, refrain from watering and let them get the nutrients they need from the rainwater.

Common Pests & Diseases About Bigleaf magnolia

Common issues for Bigleaf magnolia based on 10 million real cases
Brown spot
Brown spot Brown spot
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Plant dried up
Plant dried up Plant dried up
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Yellow spot
Yellow spot Yellow spot
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.
Leaf Weevils
Leaf Weevils Leaf Weevils
Leaf Weevils
Leaf Weevils are insects that feed on the leaves of plants.
Solutions: Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do: Spray the foliage with an insecticide Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil. Dig into the soil around plants with a garden fork and remove and dispose of any larvae. Let chickens roam around the garden, as they love to feed on weevil larvae.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
  3. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Yellow spot
plant poor
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Overview
Overview
Yellow spot is a common condition that affects all types of plants -- flowering ornamentals, trees, shrubs, herbs, and vegetable plants -- worldwide. Yellow spots may appear because of dozens of potential causes and occur in various environmental and climatic conditions, but fortunately, most are easy to address. The most common causes of yellow spots include diseases, nutrient deficiency, watering problems, and pests.
In most cases, yellow spots can be treated without permanent damage to the plant. However, in some fungal disease cases, nothing can be done to treat the disease after infection, and the plant will ultimately perish from the disease.
Due to this, the most critical aspect of addressing yellow spots on plants is correctly determining the cause.
Symptom Analysis
Symptom Analysis
Symptoms occur on varying parts of the plant, depending upon the cause. Smaller spots tend to be indicative of younger infections or newly developing problems.
  • Small yellow spots appear on leaves
  • Spots can occur on the lower or upper leaf surfaces, or both
  • Raised, rounded, or sunken spots with fringed or smooth edges
  • Spots may grow together, causing leaves to become totally discolored
  • Stunted growth
  • Premature leaf drop
Disease Cause
Disease Cause
The vast majority of yellow spot diseases are caused by fungal pathogens. However, there are some situations in which bacteria, environmental conditions, or other issues may be blamed.
Diseases are typically host-specific, so they may only affect plants within the same family. That said, just about every single species of plant is vulnerable to at least one disease that causes yellow spot. The most common problems are leaf blight, leaf septoria, powdery mildew, and downy mildew, to name a few.
All plants need specific nutrients from the soil to survive. When these nutrients become depleted or unavailable for plant uptake due to particular conditions, deficiencies occur, and yellow spots are seen.
  • Nitrogen is an integral component of chlorophyll.
  • Iron is needed in the enzymes that make chlorophyll.
Yellow spots may also appear because of incorrect watering, mainly underwatering, or infestations of sap-sucking pests such as aphids.
  • Too little water inhibits photosynthesis. Too much water pushes oxygen out of the soil and the roots cannot take in nutrients or even water from the soil.
  • Insect problems can cause yellow spots directly by damaging leaf tissue when feeding, or they may introduce pathogens.

Leaf Weevils
Leaf Weevils are insects that feed on the leaves of plants.
Overview
Overview
Leaf Weevils are insects that feed on the leaves of plants. They can cause major damage to both edible and non-edible plants. Watch out for these garden pests and use control measures to get rid of them as soon as the problem is noticed.
Symptom Analysis
Symptom Analysis
Leaf Weevils are small flightless insects that are typically around 6 mm long. They have a hard body that is oval shaped and covered in short hairs, a long snout on their head that is downward facing, and 3 pairs of legs with hooked claws.
Once mated, the female weevil with lay around 20 eggs at one time, either in leaf litter on the ground or sometimes on the soil. Weevils generally only produce one batch of eggs a year but may produce 2 if conditions are ideal.
The eggs take around 6 to 15 days to hatch. When the larva emerges, it burrows into the soil. These larvae have chewing mouth parts and no legs. They feed on the roots of the plants. When this happens, you may see signs of wilting of the leaves, stems, and flowers as the plant can’t deliver enough water from the roots to the above-ground growing parts.
Eventually, the larva evolves into a soft white pupa. The pupating period normally takes around 1 to 3 weeks. After this, the adult leaf weevil will emerge and crawl up the plant to feed on the leaves.
Adult leaf Weevils feed on young leaves, stems, flowers, and buds of almost any plant. This includes many varieties of fruits and vegetables as well as ornamental plants. This creates irregular round holes in the leaves. These holes normally start at the edges of the leaf. Holes may also be made in flowers, lesions may be caused on the skin of fruit, and sometimes whole stems are chewed off.
These insects prefer a humid environment with warm temperatures. They are mostly active during the night and will hide in leaf litter, mulch, and other debris during the day.
Solutions
Solutions
Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do:
  • Spray the foliage with an insecticide
  • Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil.

Common Pests & Diseases About Bigleaf magnolia

Common issues for Bigleaf magnolia based on 10 million real cases
Brown spot
Brown spot Brown spot Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Plant dried up
Plant dried up Plant dried up Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

Yellow spot
Yellow spot Yellow spot Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Solutions: Diseases Fungicides can prevent the transmission of spores, but they may not treat the established infection. The first step is removing and disposing of all infected plant parts. Then apply recommended chemicals. For bacterial infections, apply a spray containing copper or streptomycin. For fungal infections, consult the local cooperative extension for recommendations on which fungicides will work best. Nutrient deficiency Apply a liquid fertilizer via foliar application to fix the deficiency quickly. Follow label directions regarding dosing instructions and application notes, such as not using before the rain or when temperatures are out of the recommended range. Incorrect watering Determine the water requirements for your specific plant, and follow accordingly. Some plants like consistently moist soil, and others like the soil to dry out slightly before being watered. Pests Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.

Leaf Weevils
Leaf Weevils Leaf Weevils Leaf Weevils
Leaf Weevils are insects that feed on the leaves of plants.
Solutions: Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do: Spray the foliage with an insecticide Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil. Dig into the soil around plants with a garden fork and remove and dispose of any larvae. Let chickens roam around the garden, as they love to feed on weevil larvae.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
  2. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
  3. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Yellow spot
plant poor
Yellow spot
Leaf spot can show up as yellow or white spots on the leaves.
Overview
Overview
Yellow spot is a common condition that affects all types of plants -- flowering ornamentals, trees, shrubs, herbs, and vegetable plants -- worldwide. Yellow spots may appear because of dozens of potential causes and occur in various environmental and climatic conditions, but fortunately, most are easy to address. The most common causes of yellow spots include diseases, nutrient deficiency, watering problems, and pests.
In most cases, yellow spots can be treated without permanent damage to the plant. However, in some fungal disease cases, nothing can be done to treat the disease after infection, and the plant will ultimately perish from the disease.
Due to this, the most critical aspect of addressing yellow spots on plants is correctly determining the cause.
Symptom Analysis
Symptom Analysis
Symptoms occur on varying parts of the plant, depending upon the cause. Smaller spots tend to be indicative of younger infections or newly developing problems.
  • Small yellow spots appear on leaves
  • Spots can occur on the lower or upper leaf surfaces, or both
  • Raised, rounded, or sunken spots with fringed or smooth edges
  • Spots may grow together, causing leaves to become totally discolored
  • Stunted growth
  • Premature leaf drop
Disease Cause
Disease Cause
The vast majority of yellow spot diseases are caused by fungal pathogens. However, there are some situations in which bacteria, environmental conditions, or other issues may be blamed.
Diseases are typically host-specific, so they may only affect plants within the same family. That said, just about every single species of plant is vulnerable to at least one disease that causes yellow spot. The most common problems are leaf blight, leaf septoria, powdery mildew, and downy mildew, to name a few.
All plants need specific nutrients from the soil to survive. When these nutrients become depleted or unavailable for plant uptake due to particular conditions, deficiencies occur, and yellow spots are seen.
  • Nitrogen is an integral component of chlorophyll.
  • Iron is needed in the enzymes that make chlorophyll.
Yellow spots may also appear because of incorrect watering, mainly underwatering, or infestations of sap-sucking pests such as aphids.
  • Too little water inhibits photosynthesis. Too much water pushes oxygen out of the soil and the roots cannot take in nutrients or even water from the soil.
  • Insect problems can cause yellow spots directly by damaging leaf tissue when feeding, or they may introduce pathogens.
Solutions

Pests
Thoroughly apply an insecticidal soap, an organic product like neem oil, or an appropriate chemical insecticide to the plant.
Prevention
Prevention
Depending on the type of plant and which specific disease is causing yellow spot, problems may be avoided by taking the following preventative steps:
  • Plant resistant varieties
  • Avoid planting susceptible varieties close together - space susceptible plants further apart from one another so it’s more difficult for the fungal spores to find new plant hosts.
  • Water wisely - water from below rather than splashing water on foliage. This can reduce the spread of both bacterial and fungal pathogens responsible for yellow spot.
  • Prune - prune as a way of getting rid of affected leaves but also to control the spread of yellow spot to new plants. Pruning can also improve air circulation to limit disease spread.
  • Rotate crops - many diseases, including downy mildew, can live in the soil over the winter and produce problems for many years. Rotate annual crops to new locations each year so that they aren’t growing anywhere in which plants in the same family were grown within the last three to four years.

Leaf Weevils
Leaf Weevils are insects that feed on the leaves of plants.
Overview
Overview
Leaf Weevils are insects that feed on the leaves of plants. They can cause major damage to both edible and non-edible plants. Watch out for these garden pests and use control measures to get rid of them as soon as the problem is noticed.
Symptom Analysis
Symptom Analysis
Leaf Weevils are small flightless insects that are typically around 6 mm long. They have a hard body that is oval shaped and covered in short hairs, a long snout on their head that is downward facing, and 3 pairs of legs with hooked claws.
Once mated, the female weevil with lay around 20 eggs at one time, either in leaf litter on the ground or sometimes on the soil. Weevils generally only produce one batch of eggs a year but may produce 2 if conditions are ideal.
The eggs take around 6 to 15 days to hatch. When the larva emerges, it burrows into the soil. These larvae have chewing mouth parts and no legs. They feed on the roots of the plants. When this happens, you may see signs of wilting of the leaves, stems, and flowers as the plant can’t deliver enough water from the roots to the above-ground growing parts.
Eventually, the larva evolves into a soft white pupa. The pupating period normally takes around 1 to 3 weeks. After this, the adult leaf weevil will emerge and crawl up the plant to feed on the leaves.
Adult leaf Weevils feed on young leaves, stems, flowers, and buds of almost any plant. This includes many varieties of fruits and vegetables as well as ornamental plants. This creates irregular round holes in the leaves. These holes normally start at the edges of the leaf. Holes may also be made in flowers, lesions may be caused on the skin of fruit, and sometimes whole stems are chewed off.
These insects prefer a humid environment with warm temperatures. They are mostly active during the night and will hide in leaf litter, mulch, and other debris during the day.
Solutions
Solutions
Leaf Weevils are relatively easy to control once their presence is discovered. Here’s what to do:
  • Spray the foliage with an insecticide
  • Place sticky traps around the lower trunks of fruit trees and other woody plants. Weevils can’t fly, and have to crawl up the plants when they emerge from the soil.
  • Dig into the soil around plants with a garden fork and remove and dispose of any larvae.
  • Let chickens roam around the garden, as they love to feed on weevil larvae.
Prevention
Prevention
There are various ways to keep leaf Weevils away from plants.
  • Remove weeds such as dandelion, capeweed, portulaca, mallow, sorrel, and dock. Leaf Weevils are attracted to these weeds and will set up a colony.
  • Make sure fruit trees are well spaced from each other. This ensures that the weevils and their larvae don’t spread from one tree to the next.
  • Cultivate the soil before planting a new crop. This allows any larvae or pupae in the soil to be unearthed and disposed of.
  • Regularly fertilize the soil to encourage both earthworm and microbial activity.
  • Check plants regularly to see any signs of leaf weevil activity. Also check under loose bark, mulch, leaf litter, and in the junction of stems on the plant.

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Insufficient light
Bigleaf magnolia thrives in full sunlight but is sensitive to heat. As a plant commonly grown outdoors with abundant sunlight, it may exhibit subtle symptoms of light deficiency when placed in rooms with suboptimal lighting.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your bigleaf magnolia may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Bigleaf magnolia enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Excessive light
Bigleaf magnolia thrives in full sun exposure but is sensitive to heat. Although sunburn symptoms occasionally occur, they are unable to withstand intense sunlight in high-temperature environments.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
Bigleaf magnolia is naturally found in forested areas with warm, humid climates. It prefers a temperature range of 59 to 95 ℉ (15 to 35 ℃) for optimal growth and development. During the summer season, it can tolerate slightly higher temperatures as long as it is provided with sufficient water. In the winter, it can withstand temperatures as low as 14 ℉ (-10 ℃), but may need protection from freezing winds.
Regional wintering strategies
Bigleaf magnolia has some cold tolerance and generally does not require any additional measures when the temperature is above {Tolerable_growing_temperature_min}. However, if the temperature is expected to drop below {Tolerable_growing_temperature_min}, it is necessary to take some temporary measures for cold protection, such as wrapping the plant with plastic film, fabric, or other materials. Once the temperature rises again, the protective measures should be removed promptly.
Important Symptoms
Low Temperature
Bigleaf magnolia has moderate tolerance to low temperatures and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the leaves may start to droop. In mild cases, they can recover, but in severe cases, the leaves will wilt and eventually fall off.
Solutions
Trim off the frost-damaged parts. Prior to encountering low temperatures again, wrap the plant with materials such as non-woven fabric or cloth, and construct a wind barrier to protect it from the cold wind.
High Temperature
During summer, Bigleaf magnolia should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, the leaf tips may become dry and withered, the leaves may curl, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
