Managing Spider Mites and Winter Dormancy for Indoor Lavender

Managing Spider Mites and Winter Dormancy for Indoor Lavender

Lavender is a Mediterranean perennial that requires a winter dormancy period. Spider mites on your south‑window plant are a secondary issue.

Immediate Mite Control

Take the plant to the sink and blast all foliage with a strong spray of water. This physically removes mites and webs.

Mandatory Winter Rest

• After mite treatment, move the plant to a cold (30–40°F), dark location—an unheated garage, basement, or even a paper bag in a cold room.
• Water sparingly: ½ cup once a month to prevent total desiccation.
• After 90 days, check for new growth. Then return to a sunny window and resume normal care.

Without this cold rest, lavender weakens and eventually dies, even if pests are controlled.
