I brought my Lavender container plant inside exactly a week ago to protect it from the weather. It's doing great!!! I would like to 'overwinter' it and try to save it until next spring. (this is the first yr. so no flowers, expect flowers next yr) (I never 'overwintered anything before'). It's in the garage temporarily. Should I spray it for any insects that might be lurking in the soil? Or just rinse it in water and let it drain out the bottom (thought I read that somewhere). That won't kill any insects that may be in there. It really looks good (knock wood!) Should I take it out and put it by a sunny window or leave in the garage? (there is a window in the garage) Thanks!

What is your climate zone and which lavender do you have? What is the coldest temperature your garage will get to?

I am in zone 3 and overwinter my Munstead lavender outdoors in the ground. No special treatment and most survive very well. One survived for many years altho I've moved them a few times so no longer am sure which one that is or if it's still there.

However a few years ago I bought a lavender that was about a zone 8 and at first I thought I'd just use it as an annual but it was so pretty that I overwintered it in the house on my laundry room counter right by the window. Before I brought it in I took it out of the pot, washed the roots, and re-potted in fresh good quality potting soil. It survived and I planted it in the garden the next spring. I didn't try to save it the next winter as find house plants too much bother now.

I don't believe that lavender attract many insects as the plant is used as an insecticidal.

Wavy, I'm across the river from you and my lavender always stays outside. Its planted in the ground and does just fine with some mulch. I don't know the variety tho.

I have had Lavender growing here for many years, outside, and it has never had a problem with the winters we have. I understand, however, that there are some Lavender cultivars that are not hardy in Zone 5 and colder, so what Wavy needs to do can depend on which culitar she has.

Live in Eastern PA zone 6b and have had lavender for years but never took any inside over winter but IF you could bring it through the winter with no damage to the plant-it would sure make the room smell nice!

Good luck.
