In this blog post we’ll go over why your lavender might be turning brown and some of the possible solutions for getting them healthy again. Read on for our quick guide about keeping your precious flower beds looking vibrant!
The Most Common Reasons Lavender Turns Brown
Watering Issues
Lavender needs regular, small amounts of water but can suffer from both over and under-watering. If you water too much your plants will become more susceptible to root rot, while watering too little will cause the leaves to dry out and turn brown.
Heat Stress
Lavenders thrive in a warm climate but too much heat can cause them to wilt or burn which leads to browning of the foliage. It is important to watch out for sudden changes in temperature or prolonged exposure to high temperatures that could cause the plant’s leaves and stems to scorch. [1]
Pest Infestation
Pests such as aphids, spider mites, thrips, whiteflies and mealybugs can all damage lavender plants. These pests can cause the foliage to turn brown and die off. If you suspect your plant may have been infested, take a look at the stems and leaves for signs of insect activity such as webs or mites.
Nutrient Deficiencies
Lavender requires specific amounts of nutrients in order to thrive. If there is an imbalance or lack of certain minerals or other essential elements, the leaves will start to yellow and eventually turn brown. It’s important to make sure your lavender is getting all of the necessary nutrients it needs in order to stay healthy.
Disease
Certain diseases can affect lavenders too, with common culprits being root rot and mildew. These diseases can cause the leaves to become discolored and start to die off, leading to browning of the foliage. If you suspect your plants may be affected by disease, take a look at the roots for any signs of rot or inspect the leaves for mildew.
Seasonality
Lavender is a perennial plant which means it has a life cycle that follows the changing of seasons. In some cases, the foliage may turn brown during winter or other times of dormancy as part of its natural lifecycle. It’s important to keep this in mind when looking for signs of damage or disease.
Not Pruning
Pruning lavender regularly is important in order to keep it healthy and encourage new growth. If you don’t prune your plants, the old foliage can die off and become brown or brittle. It’s recommended to prune your lavender plants once a year to promote healthful growth and ensure that the plant stays vibrant and green.
Wrong Companion Plants
Lavender does not always play well with other plants. If you are planting lavender in close proximity to other plant species, make sure that they are not prone to the same pests or diseases as lavender. Otherwise, your plants may be at risk of becoming affected by the same problem and turning brown. [2]
Incorrect pH Levels
The pH balance of your soil is also important for maintaining a healthy lavender plant. Lavenders prefer soils with a slightly acidic pH level between 6.0-7.0; if the soil becomes too alkaline it can cause the leaves to become yellow and eventually turn brown. It’s best to test the pH levels of your soil every few months to ensure that everything is within acceptable ranges for your plants.
What To Do?
When your lavender starts to turn brown, it can be disheartening. Fortunately, there are ways to revive your plant and keep it looking its best.
The first step is to identify the cause of the discoloration. Is it due to overwatering, not enough light, or too much fertilizer? Knowing why the leaves are turning brown will help you take the necessary steps for recovery.
If the cause is lack of light, you should move your plant to an area with more sun exposure. Make sure it gets around 6 hours of direct sunlight per day to promote healthy growth and discourage browning.
Fertilizer can also be a possible culprit for discoloration in lavender plants. If this is the case, reduce or eliminate the fertilizer altogether and wait for new growth before using again. Over-fertilization can burn roots and leaves, causing them to turn brown.
Finally, if it seems like none of these solutions are helping, consider pruning away affected branches or repotting into fresh soil—both of which could potentially help revive your plant back to its original beauty.
By taking the right steps for prevention and recovery, you can keep your lavender looking healthy and vibrant for many years to come. And who doesn’t love a beautiful, fragrant lavender plant? It certainly adds a lot of charm to any garden! [3]
Treatment Tips
When it comes to treating lavender turning brown, the main focus should be on improving its environment. Here are a few things you can do:
- Water lavender regularly and deeply but avoid over-watering. Make sure the soil is moist without being soggy.
- Position your plant in an area that receives plenty of sunlight throughout the day. Lavender loves direct light but too much sun can cause burn spots or wilting.
- Prune your plant every 2 weeks to get rid of dead, dying, or diseased branches and buds that may have been affected by pests or diseases.
- Apply a balanced fertilizer twice a month during the growing season (spring and summer) to promote healthy growth.
- Improve the soil by applying a layer of mulch or compost to keep moisture in the soil and protect the roots from extreme weather conditions.
- Check for pests regularly and take prompt action if you spot any. Treat affected plants with an insecticide or pesticide as soon as possible.
Following these tips can help improve your lavender’s environment, preventing it from turning brown and helping it flourish.
Will Brown Lavender Turn Purple Again?
Unfortunately, once lavender turns brown, it is not likely to turn back to its original purple hue. The cause of the discoloration (usually due to lack of water or other environmental conditions) has caused a permanent change in the color of the plant’s leaves and stem.
However, there are some steps you can take to prevent further damage and help keep your lavender healthy and looking its best:
- Provide adequate water – Lavender needs plenty of water during hot, dry summer months; aim for 1-2 inches per week during this time. Water at the base of the plant rather than from overhead.
- Prune damaged stems and foliage – Trim off any dead or browning leaves and stems to encourage the healthy growth of new shoots.
- Fertilize lightly – Lavender needs only a small amount of fertilizer each year; a time-release fertilizer specifically for lavender is best.
- Place in full sun – Lavender needs at least 6 hours of sunlight per day to thrive, so it’s important to pick an area with plenty of sunshine.
- Avoid over watering – Too much water can lead to root rot, which will cause the plant to die or become discolored. Let the soil dry out between watering sessions and check for drainage issues that may be causing unwanted moisture buildup near the roots.
By following these steps you can keep your lavender healthy and looking its best. While it won’t turn back to its original color, you can still enjoy the beauty of this unique plant for many years to come! [4]
Should I Prune My Brown Lavender?
If your lavender is turning brown, the first thing to do is check for signs of disease or insect damage. If you don’t see any evidence of pests or diseases, it’s likely that your lavender is just too old and needs to be replaced.
If you’re unsure if there are live stems beneath the dead tissue, or if you’re unsure of how to prune your plant correctly, it’s always best to consult a knowledgeable gardener before taking any action.
Regardless of whether you choose to prune or replace your brown lavender, remember that regular care and attention can help ensure the health of this fragrant herb. Water regularly and make sure there is adequate sunlight for optimal growth. With proper care, you can enjoy the beauty and fragrance of healthy lavender in your garden for years to come.
