Can lavender recover from overwatering?
Root rot is a common problem caused by overwatering that results in a lavender plant dying. If you suspect root rot you must act quickly to save the plant. Remove the plant from the soil and prune off any affected roots. Then replant the lavender in well-draining soil.
Lavender can be propagated using water. However, because lavender is susceptible to root rot, it can be tricky and we have found that soil propagation is the best method for our needs. Quick tips: To propagate using water, fill a glass about half way with water.
The only way to revive lavender that has been in the shade is to transfer it to a pot and place it in the sun as quickly as possible. Lavenders require sun all year round, including during the winter dormancy so plant the lavender in a nice open space that is not under a tree canopy or any other shade.
Lavenders will recover from their drooping appearance if you have been watering them too frequently but leave it dry for at least 3 weeks to recover so the roots can dry out and recover properly.
Look for the following signs you are overwatering your Lavender Plant; Generally yellowing leaves, often affecting lower leaves first. Drooping despite getting plenty of water. A rotting smell from the soil can indicate root rot.
Overwatered plants can sometimes recover on their own, but it depends on the plant and the extent of the overwatering. If the roots have rotted, the plant will likely not recover. However, if the overwatering has only caused the leaves to wilt, the plant may be able to bounce back.
Remember, Lavender thrives on fast-draining soil and does not prefer to have "wet feet," or standing water, which can cause roots to rot.
Lavender can also be planted in large containers, 30-40cm (1ft-16in) in diameter. Water well, then water at regular intervals (once or twice a week) during summer, if weather is hot and the compost begins to dry out.
How to Care for Lavender. Water once or twice a week after planting until plants are established. Water mature plants every two to three weeks until buds form, then once or twice weekly until harvest. (Yellowing leaves are often a sign of overwatering.)
Let's find out. Cold hardy lavender does actually exist. The English varieties can withstand temperatures of -20 degrees Fahrenheit (-29 C.) while the French can only withstand temperatures of 10 degrees Fahrenheit (-12 C.) or higher.
Why is my lavender turning brown and dying?
Lavenders turn brown is because of root rot. The symptoms of root rot are brown, foliage, stems and even flowers. The cause of root rot is because there is too much moisture around the roots of the lavender as a result of slow draining soil or over watering.
Symptoms Roots develop a discolored vascular system and rot. Aboveground plant parts wilt and dieback. Foliage may be off color at first before it collapses. In general, root rots due to Pythium do not move up into the stem area like Phytophthora does.
- – Water Immediately After Transplanting.
- – Choose the Right Season to Transplant.
- – Provide the Right Amount of Water.
- – Move the Plant to a Bigger Pot.
- – Do Not Over Fertilize Your Soil.
- – Make the Soil Porous With Sand and Grit.
- – Keep Them in the Sun.
Water the plant in well with cold camomile tea and place it in a brightly lit spot but away from direct sunshine for it to recover. After this, water only very sparingly as the potting mix begins to dry out.
If your lavender has root rot, pull the plant from the soil and trim off the affected roots. Improve drainage in the area and replant, or move the lavender to a more suitable space protected from excessive rain and compacted soil.
Lavender should not be planted in sites in which water sits after a heavy rain for longer than a few minutes. These sites are likely to be saturated for extended periods over the winter, when drainage is impeded by frost and snow cover.
Lavender needs full sun and good drainage. It is more likely to die from excess moisture than from cold in winter. A pot is an excellent way to provide drainage, though the plant will be more vulnerable to cold temperatures than it would be in the ground.
Light/Watering:
Lavenders demand full sun, although afternoon shade may be appreciated in the hottest climates. Plants are very drought resistant once established, but will flower better if not allowed to dry out.
Soil temperatures above 65°F (18°C) favor growth and regeneration after harvest. However, the plant can definitely tolerate lower temperatures as well. High humidity favors the development of fungal diseases, while extreme summer heat affects negatively the quality of products (floral stems, essential oil).
A finger test is recommended to find out whether the Lavender needs watering. To do this, stick a finger about 1.18 to 1.57 inches deep into the ground. Water the lavender only if the substrate feels dry — preferably in the morning, so that the water can evaporate during the day.
What time of day should I water lavender?
Always water lavender in the morning which gives the soil a chance to dry during the day so moist conditions do not linger overnight.
Lavender grown in a pot requires more regular watering than in the open ground. Nevertheless, water potted lavender in moderation during the cold months and make sure that excess water can drain away. In the garden bed, water your lavender in winter only when needed, if the soil is frost-free and permeable.
Outdoor lavender does not need watering in winter. Potted lavender brought inside for winter protection need watering once every 4-6 weeks. Indoor lavender will need to be watered every two weeks and as often as every 10 days in high temperatures. What is this?
BEFORE YOU WATER
All of the soil should be dry before watering again. If the soil is still moist, you risk giving the plant too much water and it can rot.
So here's the technical stuff for the botany nerds, like myself: Lavandula augustifolia, otherwise known as English lavender, has long been grown because of it's cold hardiness. The problem is that when the scorching sun and 100 degree days roll around, it tends to wither and die.
Test it by cutting a small stalk close to the base. If it snaps easily, that stalk is dead. Test several more stalks around the base of the plant before giving up hope – sometimes a plant can die out in one section, but still have life left in others.
Lavender shrubs bear bright, fragrant blossoms and can live for 20 years or more. However, after six or eight years, they can begin to look woody, filled with dead wood and bearing fewer of their sweet-smelling flowers.
Lavender bushes need to be cut back every year to keep them from growing out of control. “Pruning lavender keeps it looking full, encourages new growth and flowering, and gives you lots of fresh tips to harvest throughout the season,” says Amy Fedele, a home gardening expert and Pretty Purple Door blogger.
Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant. However, if some healthy, white, firm roots exist, try to bring the plant back to good health by replanting in fresh soil with good drainage.
It is not possible to reverse root rot. The treatment of this disease involves removing the affected portions of the plant. Once the rotting or dying parts have been removed, they can then be repotted in fresh soil to give the remaining healthy roots a fresh start.
What to do when lavender gets woody?
If you didn't cut back after blooms faded, you can prune into fall (but not too late in the year in hard frost areas). Try regenerating a woody plant by pruning the remaining green down almost to the wood and hope for new growth. Dry wood on lavenders will not re-sprout, according to experts.
In cold climates with English lavenders the old growth may turn a gray colour and appear dead after a harsh Winter but it will come back with new growth and stems emerging in the Spring.
The lavender plant often turns gray due to fungal infections. Make sure to not overwater them. This Mediterranean plant grows best in warm conditions. During winter when it is exposed to cold weather, it turns gray as a result of frost damage.
- Stop watering. It's obvious, but don't give your plant any more water, no matter how much it wilts.

Hang the lavender bunches in a warm, dry location with good air circulation. An open window or fan nearby will help. Drying lavender in a dark place (out of direct sunlight) will improve color retention. The time it takes to fully dry can vary from a couple of weeks to over a month, depending on your climate.
Hang bundles upside down to dry in a dark, warm spot. Protect drying lavender from sunlight to retain best color, and place a sheet beneath the bundles to catch any buds or blooms that might fall. You should have dried lavender bunches in about seven to 10 days, depending on humidity.
