Lavender is a hardy plant that can survive in direct sunlight, but it will eventually die from intense exposure. If you are growing lavender yourself, be sure to shelter it from the sun during the hottest part of the day.
You can also purchase lavender plants that have been bred for southern climates and will not suffer as greatly in direct sunlight. If your lavender does get too much light, move it to a shaded area or inside during peak sun hours.
To keep your homegrown lavenders healthy and vigorous, fertilize them every two weeks with an organic fertilizer diluted 1/2 water and 1/2 composted manure.
Why Is My Lavender Dying That’s in the Sun
Lavender is a hardy herb that can withstand direct sunlight. However, over time, the intense rays of the sun can damage its leaves and flowers.
The most common cause of lavender dying in the sun is too much water or fertilizer being applied at once.
This causes plant roots to grow into the soil, displacing air and moisture which triggers fungal growth and eventual death of Lavender plants
Getting Too Much Sun Exposure
The most common reason that lavender plants die is due to getting too much sun exposure.
Lavender needs direct sunlight in order to grow, but if you’re growing your lavender near a window or other areas of intense light, it may not be able to get the necessary amount of sunlight it needs and will eventually die.
Heavy Clay Soil
If your soil is heavy with clay and doesn’t have drainage capabilities, waterlogging can occur which will kill your lavender plant.
Waterlogging occurs when there is too much moisture present in the soil which drowns the roots of the plant and prevents them from absorbing water properly leading to wilting and death.
Waterlogging or Over-watering
Waterlogging can also happen when there is excess rainwater collecting on top of the ground where your lavenders are located; this extra water can cause soil erosion that leads to flooding and ultimately kills your plants.
Watering your plants too much can also kill them off because it takes away their ability to retain moisture.
Lavender is particularly susceptible to this type of damage because it loves moist soil conditions but cannot tolerate excessive watering.
Poor Drainage & Irrigation Systems
A poorly designed irrigation system or inadequate drainage systems can also lead to root problems such as water logging, especially if there are hills or other obstacles blocking proper flow around the plants’ area.
Lack of Water
When plants are in direct sunlight, they may not be getting the water that they need to grow and flourish. This can lead to a decline in the color of your lavender and an eventual death.
If you are not providing your lavender with the correct amount of fertilizer, it will struggle to thrive and will eventually die off due to a lack of nutrients or too much salt content in the soil mix.
Some Other Reasons for Dying a Lavender Plant
There are some other reasons why a Lavender plant might die, but the most common ones include improper watering, over-fertilization, and having an acidic soil pH.
Check out these reasons to identify the reason of dying your Lavender plants:
Pests & diseases
Pests and diseases can ruin a lavender garden quickly by eating away at buds and leaves, causing the plant to decline rapidly in health.
Keep an eye out for aphids (small green bugs), whiteflies (tiny flying insects), pink ladybugs (a beneficial insect that feeds on harmful larvae), thrips (mites that feed on sap from plants), molds (fungi that grow on damp surfaces such as walls or ceilings), scale insects (flat-looking bugs that suck blood from plants) or mealybugs (a type of soft-bodied pest).
If you notice any signs of damage or disease, be sure treat them immediately.
One of the most common reasons for dying a lavender plant is due to fungal infection. This type of infection can be caused by many different types of fungi, and it can affect both the leaves and flowers on your plants.
Lavender is particularly susceptible to this type of infection because it has long stems and delicate flower buds.
Lavender plants are also prone to insect damage, which can lead to fungal growth or even death in some cases.
The most common insects that cause damage to lavenders are aphids and scale bugs, but other pests such as mealybugs may also cause problems.
Poor Watering Practices
Another reason why a lavender plant might die is if it isn’t receiving enough water.
Not enough water will dehydrate the plant tissues, which will then allow fungus or pests access to the root system and towards the trunk of the plant.
Too Much Fertilizer/Pesticides/Water Contamination
Finally, over-fertilization or exposure to pesticides or contaminated water can also kill your lavender plants.
Caring Tips on Lavender Plants
Lavender is a popular plant that can be used for both culinary and floral purposes.
Unfortunately, over-watering lavender can cause it to wilt and eventually die. Here are some tips on how to save over-watered lavender:
Drain and Add Fresh Water
If your lavender is overgrown or not getting enough water, the first step is to drain and then add fresh water.
This will help to get the plant back on track and give it the necessary hydration it needs.
Check for Nutrients Deficient
If there are deficiencies in nutrients such as nitrogen, phosphorus, potassium, magnesium or organic matter, then supplemental fertilizers may be necessary to help restore balance in the soil where your lavender grows.
A layer of mulch around a young tree will hold moisture in during dry periods and protect against wind damage as well as provide a protective barrier from cold temperatures at night.
Feed Lavenders with Nitrogen-Rich Meal Worms
If you live in an area that experiences drought conditions often or if your lavender plants do not seem to be thriving despite adequate watering, consider feeding them nitrogen-rich mealworms instead of solely relying on irrigation drenches or fertigation services which can be costly.
Get a Good Soil
Lavender plants need good, well-drained soil in order to thrive. Make sure the soil is loose and friable, but not too dry or wet. A good way to test if the soil is ready is to dig up a small area and see if it forms clumps when you add water.
Prune Dead Branchlets Regularly
Remove any dead branchlets so they don’t accumulate excessive amounts of sap which can lead to wilting foliage.
Try Not to Overdose on Fertilizer
Too much fertilizer can actually kill your lavender plant, so make sure you use a diluted formula that specifically contains nutrients for this type of plant.
Keep an Eye Out for Pests
In addition to regular watering and fertilizing, be on the lookout for pests like aphids, which are tiny insects that feed on leaves; mealy bugs, which secrete honeydew; scale insects; thrips; spider mites; whiteflies, etc., all of which can cause damage to your lavender plant(s).
Treat these pests as soon as possible with our recommended pesticides or solutions according to the instructions accompanying the product.
Can Lavender Get Too Much Sun?
Lavenders do best in full sun, but can tolerate a little shade. If your lavender is growing in full shade, it is likely that the plant is too young to tolerate direct sunlight and needs to be moved to a brighter location.
How Do You Revive Lavender Dying?
If lavender is in a pot, you can transfer it to a sunnier location as quickly as possible.
Can You Overwater Lavender?
No, you cannot. Over watering will cause the plants to rot and die.
Why Does My Lavender Look Sad?
One possibility is that the lavender is getting too much direct sunlight and is being damaged by the heat. Another possibility is that the lavender may be getting more water than it needs, leading to it looking sad.
If your Lavender is dying in direct sunlight, it’s likely due to a combination of factors.
Over-watering and poor drainage can both lead to plants living in waterlogged soil, which causes them to become dehydrated and weak.
This also encourages pests and diseases, as they thrive in an environment with insufficient oxygenation.
If you see any of these symptoms on your Lavender plant, take measures to correct the problem before it destroys the entire plant.
