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

What should I do if I water Winter hazel too much/too little?
An overwatered Winter hazel 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 Winter hazel 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 Winter hazel 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 Winter hazel 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 Winter hazel?
The Winter hazel 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.Winter hazel 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 Winter hazel?
The Winter hazel 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 Winter hazel is planted outdoor with adequate rainfall, it may not need additional watering. When Winter hazel is young or newly planted, make sure it gets 1-2 inches of rain per week. As Winter hazel 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 Winter hazel 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 Winter hazel according to different seasons or climates?
The Winter hazel 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 Winter hazel 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 Winter hazel will need less water during the winter. Since the Winter hazel 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 Winter hazel growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases Winter hazel can rely on the fall and winter rains to survive the entire dormant period. After the spring, you can cultivate your Winter hazel 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 Winter hazel’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 Winter hazel’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 Winter hazel in different seasons, climates, or during different growing periods?
If planting in the ground, Winter hazel 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 Winter hazel 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 Winter hazel 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 Winter hazel important?
Watering the Winter hazel 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 Winter hazel 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 issues for Winter hazel based on 10 million real cases
Gall
Gall Gall
Gall
Insects or diseases can cause strange protrusions on the leaves, sometimes manifesting in a range of colors and shapes.
Solutions: While galls may look alarming, the physical structures themselves pose little threat to the plant or tree and do not require chemical treatment. If the galls are unsightly, they can be removed using sterilized (10% bleach solution) pruners or loppers. Discard or destroy all removed plant parts. It is important to treat the underlying cause, as insects or diseases can create long-term damage if left untreated. After identifying the pest, natural or chemical may be used, depending upon individual gardening preferences. To treat pests naturally apply an insecticidal soap. Dilute 1 tablespoon of soap per quart of water in a spray bottle and mix gently. Spray the entire plant until the leaves are dripping, making sure to coat the underside and tops. Re-spray every 2 to 3 days. To treat organically apply neem oil, a naturally occurring pesticide, per label directions every 7 days until pests are eradicated. To treat chemically apply an insecticidal foliar spray. Follow the dosing instructions provided by the manufacturer on the product label. For fungal or bacterial causes, apply a bactericide or copper-based fungicide in the spring, following the dosing instructions provided on the product label.
Nutrient deficiencies
Nutrient deficiencies Nutrient deficiencies
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
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.
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.

Gall
Insects or diseases can cause strange protrusions on the leaves, sometimes manifesting in a range of colors and shapes.
Overview
Overview
A general symptom of plant irritation, a gall is a spherical or lumpy, tumor-like growth that appears on leaves, stems, branches and trunks of various plants, especially trees. Galls form around a potential problem or irritation, like a pearl forming around a bit of sand in an oyster shell, to separate the cause from the rest of the plant. Many form around insect damage or a localized infection.
Symptom Analysis
Symptom Analysis
Abnormal growths appear on leaves or other parts of the plant. The brown or brightly colored bumps may be simple or complicated structures.
  • Leaf galls appear on most herbaceous plants and trees. They are more prone to develop on new growth and following mild winters in which insects and diseases were not killed by the cold.
  • Leaf galls look like leaf curls, nipples, blisters, or erineums (hairy growths) and can occur on upper or lower leaf surfaces.
  • Bud or flower galls cause these parts to be deformed in size or shape.
  • Stem and twig galls cause deformed growth on twigs and stems, with symptom severity ranging from slight swelling to large, knot-like growth.
  • Stunted plant growth is possible, as galls steal nutrients from the plant.
  • Long-lasting damage can occur if there are many galls or galls present for a long period of time.
It's important to note that galls, especially leaf galls, are extremely common. Noticing galls is not a cause to panic – most plants will have galls from time to time. However, it is when they are widespread or long-lasting that steps will need to be taken to remove them.
Disease Cause
Disease Cause
There are many different processes and organisms that produce galls. Some appear when sap-sucking insects feed on leaves; some shelter developing insect eggs; some develop as a response to fungal or bacterial infection.
The most common culprits include:
  • Feeding or egg-laying mites and insects - the saliva and other secretions cause the plants to produce more growth hormones.
  • High hormone production resulting in increased cell numbers or cell size (because of this, mature plants tend not to be affected).
  • Fungal infection
  • Galls forming on leaf blades and sheaths are more often caused by viruses or bacteria.
  • Nematodes can also cause galls to form on plants, but these tend to form in the roots.
  • Parasitic plants such as mistletoe can cause galls on their hosts.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.

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.

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.

Insects or diseases can cause strange protrusions on the leaves, sometimes manifesting in a range of colors and shapes.
Overview
Overview
A general symptom of plant irritation, a gall is a spherical or lumpy, tumor-like growth that appears on leaves, stems, branches and trunks of various plants, especially trees. Galls form around a potential problem or irritation, like a pearl forming around a bit of sand in an oyster shell, to separate the cause from the rest of the plant. Many form around insect damage or a localized infection.
Symptom Analysis
Symptom Analysis
Abnormal growths appear on leaves or other parts of the plant. The brown or brightly colored bumps may be simple or complicated structures.
  • Leaf galls appear on most herbaceous plants and trees. They are more prone to develop on new growth and following mild winters in which insects and diseases were not killed by the cold.
  • Leaf galls look like leaf curls, nipples, blisters, or erineums (hairy growths) and can occur on upper or lower leaf surfaces.
  • Bud or flower galls cause these parts to be deformed in size or shape.
  • Stem and twig galls cause deformed growth on twigs and stems, with symptom severity ranging from slight swelling to large, knot-like growth.
  • Stunted plant growth is possible, as galls steal nutrients from the plant.
  • Long-lasting damage can occur if there are many galls or galls present for a long period of time.
It's important to note that galls, especially leaf galls, are extremely common. Noticing galls is not a cause to panic – most plants will have galls from time to time. However, it is when they are widespread or long-lasting that steps will need to be taken to remove them.
Disease Cause
Disease Cause
There are many different processes and organisms that produce galls. Some appear when sap-sucking insects feed on leaves; some shelter developing insect eggs; some develop as a response to fungal or bacterial infection.
The most common culprits include:
  • Feeding or egg-laying mites and insects - the saliva and other secretions cause the plants to produce more growth hormones.
  • High hormone production resulting in increased cell numbers or cell size (because of this, mature plants tend not to be affected).
  • Fungal infection
  • Galls forming on leaf blades and sheaths are more often caused by viruses or bacteria.
  • Nematodes can also cause galls to form on plants, but these tend to form in the roots.
  • Parasitic plants such as mistletoe can cause galls on their hosts.
Solutions
Solutions
While galls may look alarming, the physical structures themselves pose little threat to the plant or tree and do not require chemical treatment. If the galls are unsightly, they can be removed using sterilized (10% bleach solution) pruners or loppers. Discard or destroy all removed plant parts.
It is important to treat the underlying cause, as insects or diseases can create long-term damage if left untreated. After identifying the pest, natural or chemical may be used, depending upon individual gardening preferences.
  • To treat pests naturally apply an insecticidal soap. Dilute 1 tablespoon of soap per quart of water in a spray bottle and mix gently. Spray the entire plant until the leaves are dripping, making sure to coat the underside and tops. Re-spray every 2 to 3 days.
  • To treat organically apply neem oil, a naturally occurring pesticide, per label directions every 7 days until pests are eradicated.
  • To treat chemically apply an insecticidal foliar spray. Follow the dosing instructions provided by the manufacturer on the product label.
  • For fungal or bacterial causes, apply a bactericide or copper-based fungicide in the spring, following the dosing instructions provided on the product label.
Prevention
Prevention
To prevent the common causes of gall:
  • Rake up all fallen leaves at the end of the growing season, and dispose of the leaves and all other plant debris to get rid of sites where gall producers can overwinter.
  • Avoid over-fertilizing plants, as it induces stress, making them more susceptible to pest problems.
  • Keep plants well-watered, preventing drought stress.
  • Apply dormant oil in early spring to control leaf-eating insects.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
  3. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
  4. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Aged yellow and dry

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.

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.

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
Symptoms of Insufficient Light in %s
Winter hazel is a versatile plant that thrives in full sunlight but can tolerate partial shade. While it can adapt to different light conditions, when grown indoors with insufficient light, subtle symptoms of light deficiency may arise.
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 Winter hazel 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
Winter hazel 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 optimize plant growth, shift them to increasingly sunnier spots each week until they receive 3-6 hours of direct sunlight daily, enabling gradual adaptation to changing light conditions.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.
Symptoms of Excessive light in %s
Winter hazel thrives in full sun exposure but can adapt to partial shade. Although sunburn symptoms occur occasionally, they are generally tolerant of different light conditions due to their resilience.

(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.
