What's the best method to water my American sycamore?
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 American sycamore prefers deep watering over light sprinkling.

What should I do if I water American sycamore too much/too little?
An overwatered American sycamore 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 American sycamore 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 American sycamore 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 American sycamore 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 American sycamore?
The American sycamore 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.American sycamore 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 American sycamore?
The American sycamore 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 American sycamore is planted outdoor with adequate rainfall, it may not need additional watering. When American sycamore is young or newly planted, make sure it gets 1-2 inches of rain per week. As American sycamore 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 American sycamore 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 American sycamore according to different seasons or climates?
The American sycamore 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 American sycamore 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 American sycamore will need less water during the winter. Since the American sycamore 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 American sycamore growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases American sycamore can rely on the fall and winter rains to survive the entire dormant period. After the spring, you can cultivate your American sycamore 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 American sycamore’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 American sycamore’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 American sycamore in different seasons, climates, or during different growing periods?
If planting in the ground, American sycamore 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 American sycamore 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 American sycamore 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 American sycamore important?
Watering the American sycamore 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 American sycamore 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.

Plant dried up
Plant dried up is a detrimental form of disease impacting the overall vitality of American sycamore. The disease can lead to significant loss of foliage, browning and dehydration, subtly eliminating the plant's aesthetic value and ability to photosynthesize, adversely affecting its growth, and survival.
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.
Longhorn beetles
Longhorn beetles Longhorn beetles
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Aged yellow and dry
Aged yellow and dry Aged yellow and dry
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Caterpillars
Caterpillars Caterpillars
Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Solutions: Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers. For severe cases: Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects. Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans. Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps. For less severe cases: Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water. Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.

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.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Overview
Overview
Caterpillars can cause problems for home gardeners. If not managed, these insects can defoliate a plant in just a matter of days. However, home gardeners face a challenge because these caterpillars eventually turn into beautiful butterflies and moths, which are important for pollination and the general ecosystem.
There are thousands of different species of caterpillars and many will only target certain plants. If caterpillars are posing a problem, they can be removed by hand, or gardeners can use insect-proof netting to protect their valuable plants.
Symptom Analysis
Symptom Analysis
Caterpillars are the larvae of butterflies and moths. During the warmer months, butterflies and moths that visit gardens will lay their eggs on the underside of leaves.
When the tiny eggs hatch, the young larvae emerge and start feeding on the leaves of the plant. Depending on how many larvae have hatched, they can easily defoliate the plant in a very short period of time. Caterpillars will shed their skin as they grow, around 4 or 5 times during this feeding cycle.
Symptoms of caterpillars eating plants appear as holes in the leaves. The edges of the leaves may be eaten away as well, and flowers can be affected as well.
Some are easy to see, but others need to be searched for. This is because their bodies are often camouflaged to look like part of the plant. Gardeners need to look carefully along the stems of the plant as well as under the leaves. Also, look for tiny white, yellow, or brown eggs that can be found in groups on the underside of leaves.
Once the caterpillar is fully grown, it transforms into a pupa or chrysalis. Then, after a period of time that varies according to the species, a butterfly or moth will emerge from the pupa and the cycle begins again.
Solutions
Solutions
Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers.
For severe cases:
  1. Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects.

Water
Every 1-2 weeks
American sycamore is indigenous to the humid climates of North America, establishing its roots in river banks and floodplains where moisture is abundant. Predominantly in regions that record high annual precipitation, it has evolved to stay hydrated consistently. Due to this, american sycamore demands frequent watering when cultivated domestically, albeit with fine balance, to replicate its natural, water-rich conditions without causing waterlogging.
Watering Techniques
Lighting
Full sun
The american sycamore thrives best under the full intensity of sun rays and can also endure in areas with a moderate shadow. The plant's vitality and overall health are greatly dependent on abundant light exposure. Its original environmental niche and natural habitat relate to this sun tolerance. However, both insufficient and excessive sun can cause stress, affecting its growth and well-being.
Best Sunlight Practices
Transplant
60-100 feet
The perfect time for transplanting american sycamore is during the warmth of late spring through midsummer. Choose a location with ample sun and well-draining soil for optimal growth. Gently loosen the root ball during transplant, and remember to water regularly post-transplant.
Transplant Techniques
Temperature
-25 - 38 ℃
The american sycamore requires a temperate environment, with a preferred temperature range of 41 to 95 ℉ (5 to 35 ℃). It can survive in lower temperatures, but is susceptible to frost damage in colder climates. During summer, it can tolerate higher temperatures up to 95℉ (35℃), but requires consistent moisture. In fall, the temperature adjustment suggestion is to gradually decrease water to encourage dormancy.
Temp for Healthy Growth
Pruning
Early spring, Late winter
Renowned for its broad, maple-like leaves and exfoliating bark, american sycamore requires minimal pruning to maintain health and structure. Key techniques include removing dead or damaged branches and thinning to improve air circulation. Ideal pruning occurs in late winter or early spring to promote vigorous growth. Specific attention should be given to avoiding excessive cuts as american sycamore is prone to bleeding sap. Proper pruning enhances the plant's majestic stature and prevents disease.

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.

Longhorn beetles
Longhorn beetles Longhorn beetles Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.

Caterpillars
Caterpillars Caterpillars Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Solutions: Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers. For severe cases: Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects. Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans. Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps. For less severe cases: Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water. Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.

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.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions
Solutions
Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control.
Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees.
  • Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.

  • To properly control longhorn beetles, all host plants in a given area must be treated.
  • Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Prevention
Prevention
  • Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
  • Check with local tree companies about which tree species have fewer problems.
  • Avoid moving firewood as this can introduce exotic longhorn beetles.
  • Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Aged yellow and dry
plant poor
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

Caterpillars
plant poor
Caterpillars
Caterpillars are fleshy moth or butterfly larvae that come in an array of colors, patterns, and even hairstyles. They chew on leaves and flower petals, creating large, irregular holes.
Overview
Overview
Caterpillars can cause problems for home gardeners. If not managed, these insects can defoliate a plant in just a matter of days. However, home gardeners face a challenge because these caterpillars eventually turn into beautiful butterflies and moths, which are important for pollination and the general ecosystem.
There are thousands of different species of caterpillars and many will only target certain plants. If caterpillars are posing a problem, they can be removed by hand, or gardeners can use insect-proof netting to protect their valuable plants.
Symptom Analysis
Symptom Analysis
Caterpillars are the larvae of butterflies and moths. During the warmer months, butterflies and moths that visit gardens will lay their eggs on the underside of leaves.
When the tiny eggs hatch, the young larvae emerge and start feeding on the leaves of the plant. Depending on how many larvae have hatched, they can easily defoliate the plant in a very short period of time. Caterpillars will shed their skin as they grow, around 4 or 5 times during this feeding cycle.
Symptoms of caterpillars eating plants appear as holes in the leaves. The edges of the leaves may be eaten away as well, and flowers can be affected as well.
Some are easy to see, but others need to be searched for. This is because their bodies are often camouflaged to look like part of the plant. Gardeners need to look carefully along the stems of the plant as well as under the leaves. Also, look for tiny white, yellow, or brown eggs that can be found in groups on the underside of leaves.
Once the caterpillar is fully grown, it transforms into a pupa or chrysalis. Then, after a period of time that varies according to the species, a butterfly or moth will emerge from the pupa and the cycle begins again.
Solutions
Solutions
Even though caterpillars are diverse, they all chew on plant parts and can cause significant damage if present in large numbers.
For severe cases:
  1. Apply insecticide. For an organic solution, spray plants with a Bacillus thuringiensis (Bt), which specifically affects the larval stage of moths and butterflies. Be sure to coat plants, since caterpillars need to ingest Bt for it to be effective. This will not harm other insects.
  2. Spray a chili extract. Chili seeds can be cooked in water to make a spicy spray that caterpillars don't like. Spray this mixture on the plants, but be aware it will also be spicy to humans.
  3. Introduce beneficial insects. Release beneficial insects to the garden that eat caterpillars, such as parasitic wasps.
For less severe cases:
  1. Hand pick. Using gloves, pick off caterpillars on plants and dispose of them in a bucket of soapy water.
  2. Dust plants with diatomaceous earth. This powder is harmless to humans but irritates caterpillars. Therefore, it will make it difficult for caterpillars to move and eat.
Prevention
Prevention
Prevention may require less effort than attempts to eradicate infestations that have already begun. Here are our top steps for prevention:
  1. Monitor plants. Check plants regularly for caterpillar eggs on leaves. If they do not belong to an endangered species, they should be squished.
  2. Use insect netting. Cover plants with insect netting to prevent butterflies and moths from laying eggs on plants.
  3. Apply diatomaceous earth. Apply DE to plants early in the season and reapply after rain.
  4. Encourage plant diversity. This will attract predatory insects including parasitic wasps.
