I noticed in a survey that 56% of those who grow lavender have lavender browning as their main problem. This browning can be very disheartening to the gardener because it’s always not easy to determine why it’s happening.
You may not know that a tiny problem can be enough to kill a tree. Just like people, trees need the right conditions to stay healthy. If something is off, it can affect the whole tree.
Lavender (Lavandula angustifolia) is a member of the mint family. It’s a hardy, evergreen shrub that’s easy to grow in well-drained soil in full sun. Lavender prefers warm weather and doesn’t do well in cold or damp conditions.
Lavender browning can be caused by several things, including Overwatering, Poor drainage, Fungal diseases, Pests, Nutrient deficiencies, Environmental stressors (such as cold weather or drought), and Genetics.
I will show you in this article some of the most common reasons for lavender browning and what you can do about it.
Nutrient deficiencies can cause lavender to turn brown.
Lavender is a beautiful, aromatic flower that can be used for a variety of purposes. However, if your lavender turns brown, it may be due to a nutrient deficiency. Nutrient deficiencies can cause various problems with plants, including the browning of the leaves. The most common nutrient deficiencies that can cause leaf discoloration include nitrogen, potassium, and magnesium.
1. Nitrogen deficiency
Nitrogen is an essential nutrient for all plants and is especially important for green, leafy plants like lavender. Nitrogen is responsible for the growth of leaves and stems, and a lack of nitrogen can cause the leaves to turn yellow or brown. A nitrogen deficiency can be caused by a number of factors, including over-fertilization with a nitrogen-rich fertilizer, inadequate soil nitrogen, or a lack of nitrogen-fixing bacteria in the soil.
2. Potassium deficiency
Potassium is another essential nutrient for plants, and it is responsible for the growth and development of roots, flowers, and fruit. A potassium deficiency can cause the leaves to turn brown or yellow, and the plant may be more susceptible to pests and diseases. A potassium deficiency can be caused by many factors, including over-fertilization with potassium-rich fertilizer, inadequate soil potassium, or a lack of potassium in the diet.
3. Magnesium deficiency
Magnesium is an essential nutrient for plants and is responsible for the growth and development of leaves and stems. A magnesium deficiency can cause the leaves to turn yellow or brown, and the plant may be more susceptible to pests and diseases. A magnesium deficiency can be caused by a number of factors, including over-fertilization with magnesium-rich fertilizer, inadequate soil magnesium, or a lack of magnesium in the diet.
Water problems Cause Lavender Turning Brown
When a plant’s leaves turn brown, it can be a sign that it is not getting enough water. This is often the case with lavender plants, which can turn brown if they don’t get enough water.
You can do a few things to help prevent your lavender from turning brown, such as watering it regularly and ensuring the soil is moist. If your lavender does start to turn brown, you can try and water it more often to see if that helps.
Watering your plants regularly is one of the best ways to help keep them healthy and looking their best. However, if you water your plants too much, it can cause them to die. Overwatering is one of the most common causes of plants dying, and it can be especially damaging to lavender plants.
If your lavender starts to turn brown, it could be a sign that you are overwatering it. To prevent this, only water your plant when the soil feels dry to the touch. You may also want to try watering your plant less often, which will help it retain more water.
Watering is essential to keeping plants healthy, and if a plant isn’t watered regularly, it may start to turn brown. This is because the lack of water can cause the plant to dry out, damaging the plant’s leaves and cause them to turn brown. If you’re having trouble watering your plants regularly, you may consider using a watering can or installing a watering system.
3. Improper watering of lavender plants
Watering your lavender plants improperly can cause them to turn brown. This is because if the plants are not given enough water, they will start to wilt, and the roots will rot if given too much water. It is important to water your lavender plants regularly, but not too much, to keep them healthy and looking their best.
Environmental stress can cause lavender brown.
The environmental stress of things like too much sun or wind can cause lavender brown to form on the leaves of the plants. This discoloration is unsightly and can also affect the plant’s ability to photosynthesize, leading to decreased growth or even death.
There are several ways to mitigate environmental stress in your gardens, such as locating plants properly, providing adequate water and nutrients, and using mulch or shade cloth.
1. Too much sunlight
Too much sunlight can be a major cause of environmental stress for lavender plants. The intense heat and light can damage the leaves, causing them to turn brown. This discoloration can also affect the plant’s ability to photosynthesize, leading to decreased growth or even death.
One way to mitigate this stress is to provide shade for your lavender plants. This can be done by planting them in an area with partial sun or using a mulch or shade cloth to cover them during the hottest hours of the day.
2. Too much wind
Wind can also cause environmental stress for lavender plants. The constant movement can damage the leaves and flowers, causing them to turn brown. This discoloration can also affect the plant’s ability to photosynthesize, leading to decreased growth or even death.
One way to mitigate this stress is to provide some protection for your lavender plants. This can be done by planting them in an area sheltered from the wind or using a mulch or shade cloth to cover them.
Soil problems Cause Lavender Turning Brown
The soil you are using to grow your lavender plants may be the culprit for your plants turning brown. If the soil is too acidic, it can cause the leaves of your plants to turn yellow or brown.
Additionally, if the soil is too alkaline, it can also cause the leaves of your plants to turn brown. You can test the pH level of your soil with a home testing kit to see if it is within the appropriate range for growing lavender plants. If it is not, you can take steps to amend the soil so that it is more hospitable to your plants.
1. Acidic soil
If your soil is too acidic, you can take steps to amend the soil so that it is more hospitable to your plants. One way to do this is by adding sulfur to the soil. This will help reduce the soil’s acidity and allow your plants to grow healthy and strong.
Another way to amend acidic soil is by adding organic matter to the soil. This will help improve the soil’s overall quality and make it more hospitable to your plants. You can add organic matter to the soil by adding compost or mulch to the area around your plants.
2. Alkaline soil
If your soil is too alkaline, you can take steps to amend the soil so that it is more hospitable to your plants. One way to do this is by adding organic matter to the soil. This will help improve the soil’s overall quality and make it more hospitable to your plants. You can add organic matter to the soil by adding compost or mulch to the area around your plants.
Another way to amend alkaline soil is by adding sulfur to the soil. This will help reduce the soil’s alkalinity and allow your plants to grow healthy and strong.
3. Poor Draining Soil
Lavender plants are susceptible to root rot, and poor drainage is the number one cause of this problem. If your lavender is turning brown, it’s likely because the roots are sitting in water, causing them to rot. The solution is to improve the drainage in your lavender planting bed.
Lavender also doesn’t like to be too wet, so make sure you’re not overwatering it. Let the soil dry out between waterings, and don’t water if it’s been raining a lot.
4. Compacted Soil
When a plant’s roots cannot penetrate the soil easily, the soil is said to be compacted. This can be caused by many things, such as heavy rains or foot traffic. When the soil is compacted, it becomes difficult for the plant’s roots to get the water and nutrients they need, which can cause the plant to die or turn brown.
Heavy Rainfall Issues Causes Lavender Turning Brown
Heavy rainfall is a significant threat to lavender plants. It can cause the plants to turn brown and die. Lavender is a delicate plant that does not tolerate too much moisture. Heavy rainfall can saturate the ground and cause the plant’s roots to rot. This can lead to the plant turning brown and dying.
If you live in an area with high rainfall, it is important to take steps to protect your lavender plants. One option is to plant the lavender in raised beds. This will help to ensure that the roots do not become waterlogged.
It is also important to choose a lavender variety that is tolerant of wet conditions. English lavender (Lavandula angustifolia) is a good option for gardens in wet conditions.
If you do experience heavy rainfall, be sure to check on your lavender plants regularly. If the leaves are starting to turn brown, take action to protect the plant.
You can do a few things to help save a lavender plant that is turning brown due to heavy rainfall. First, try to remove the excess water from around the plant. This can be done by gently lifting the plant and removing water pooling around the roots.
Next, cut back the brown leaves. This will help reduce the amount of moisture the plant is losing.
Finally, give the plant some extra protection from the rain. This can be done by covering the plant with a tarp or placing it in a greenhouse.
Heavy frosts cause lavender to turn brown.
Lavender plants are very susceptible to damage from cold weather and frost. If the temperature drops or there is a heavy frost, the lavender plants can turn brown and die. This is especially true for young plants that have not yet had a chance to develop a robust root system.
Lavender plants need to be protected from the cold to survive. If you live in an area that gets cold winters, it is important to plant your lavender in a location protected from wind and frost. You can also use a light mulch around the plants to help insulate them from the cold.
If your lavender plants get damaged by the cold, you can cut back the dead parts in the spring, which will usually regrow. However, it is important to note that lavender plants are not very tolerant of moving around. So, if you need to replant them, it is best to do so in the exact location where they were initially planted.
Fungal diseases cause lavender to turn brown.
Many diseases can affect lavender, but fungal diseases are one of the most common problems. Fungal diseases cause the leaves of the plant to turn brown and die. The fungus can invade the plant through the roots, or it can be spread by wind or rain. There is no cure for fungal disease, so it is important to take steps to prevent it from occurring.
To help protect your lavender plants, ensure they have plenty of air circulation and water them regularly but not too much. If you suspect your plants have a fungal disease, remove any dead leaves and dispose of them in a trash bag. Do not compost them, as the fungus may survive and infect other plants.
Fungal diseases cause lavender to turn brown.
1. Phoma Lavandulae Gab
Phoma Lavandulae Gab is a fungal disease that can cause lavender to turn brown. It is a severe problem for lavender growers and can lead to significant crop losses. The fungus attacks the leaves of the plants, causing them to turn brown and die. There is no cure for Phoma Lavandulae Gab, and the only way to protect plants from the disease is to use fungicides.
2. The “Shab” disease of lavender
Shab disease is a fungal infection that causes lavender to turn brown. The fungus responsible for this disease is Botrytis cinerea, which can cause severe damage to plants. Shab disease typically affects the flowers and leaves of lavender plants, resulting in wilting, stunting, and death. There is no cure for this disease, so it is important to take steps to prevent it from occurring.
One way to do this is to make sure that the plants are adequately watered and fertilized. It is also important to keep the area around the plants free of debris and weeds, as these can provide a breeding ground for the fungus.
3. Leaf spot
Leaf spot is a fungal disease that attacks lavender plants and causes them to turn brown. The disease is caused by a fungus that invades the plant leaves, resulting in small, black spots that can eventually cover the entire leaf. The fungus can also cause the stems and flowers of the plant to rot. Leaf spot is most common in warm, humid climates and can be treated with fungicides.
Growing lavender with the wrong Companion causes lavender browning
