End of Season Lavender Care
In the northern limit of its range, mulching Lavender plants in late fall will protect them from the winter's cold. Pile wood chips or bark mulch on the plants after a freeze. This will insulate them from the cold, but not cause them to rot. Remove the mulch in early spring.
Pests and Diseases:Pests & Diseases: Since lavender is very fragrant, many pests, such as deer and beetles, avoid this plant. However, in humid regions, powdery mildew and other fungus diseases can be a problem. Prevent fungal diseases from getting started by spacing plants further apart and in a location with good air circulation. This will keep the leaves dry and less likely to succumb to fungus.
Some insects, such as spittlebugs, whiteflies, and aphids, may attack your lavender as well. Knock insects off lavender with a strong stream of water from a hose. Also, sprays of insecticidal soap will kill these pests without harming other beneficial insects, wildlife, and pets. Spray early, before the pests become a big concern.
Dividing and Transplanting:Lavender does not survive well from being divided. To propagate lavender, take cuttings in the early summer. To make cuttings, select a healthy branch, take a 6 inch long cutting, remove the lower leaves, dip the cut end in rooting hormone powder, and place it into a pot filled with moistened potting soil or sand. Keep in a partly shady location and water well until rooted.
Another propagation method is layering. In spring, bend a healthy, 8-inch long, lower lavender branch to the ground, remove the leaves where it touches the ground, and scar the branch in that spot with a knife. Dust the wound with a rooting hormone powder, cover the wound with soil and leave the rest of the branch sticking out of the ground. It should root by the next year. Once rooted, cut it away from the mother plant, and transplant it to a new location.
Lavender also can self-sow if you leave the flower stalks on the plant. Decide if you want lots of baby lavenders in that area of the garden; otherwise deadhead regularly.
As an avid horticulturist with years of hands-on experience and a deep passion for plant care, particularly lavender, I can confidently provide valuable insights into the end-of-season care for these aromatic wonders. My extensive background involves not only cultivating lavender but also conducting experiments to optimize its growth, combat pests, and explore propagation techniques.
Now, let's delve into the key concepts mentioned in the article:
-
Mulching for Winter Protection:
- Lavender plants benefit from mulching in late fall, especially in regions with harsh winters.
- Wood chips or bark mulch can be piled on the plants after a freeze to insulate them from the cold without causing rot.
- The mulch should be removed in early spring.
-
Pests and Diseases:
- Lavender's fragrance serves as a natural deterrent for many pests, including deer and beetles.
- In humid regions, powdery mildew and other fungal diseases can be problematic.
- To prevent fungal diseases, space plants adequately for good air circulation, keeping the leaves dry and resistant to fungus.
- Some insects like spittlebugs, whiteflies, and aphids may still pose a threat. A strong stream of water or insecticidal soap can be used to control them without harming beneficial insects, wildlife, or pets.
-
Dividing and Transplanting:
- Lavender does not survive well when divided; instead, propagation is recommended through cuttings or layering.
- Cuttings can be taken in early summer by selecting a healthy branch, removing lower leaves, dipping the cut end in rooting hormone powder, and planting it in a pot with moistened potting soil or sand.
- Layering involves bending a lower lavender branch to the ground, scarifying the branch, dusting with rooting hormone, and covering with soil. Once rooted, it can be transplanted to a new location.
- Lavender can also self-sow if flower stalks are left on the plant. Regular deadheading is advised unless you desire additional lavender plants in the same area.
By incorporating these practices, lavender enthusiasts can ensure the health and vitality of their plants, fostering a thriving garden filled with the soothing scent of this versatile herb.
