Hello,
I just bought five (1.5 gallon) lavender plants from HomeDepot. It is October 10, so they were marked 50% percent off and I couldn’t help myself. I live in Zone 6 and the Lavender (unknown type) is rated for -20F.

My question is should I plant them now in October or will it not give them enough time to establish themselves and survive the winter.

I have been reading online about winterizing perennials and some say you can just bury the pot and replant in the spring. Others advice to store them in a garage or basement.

Thank you everyone in advance for their help, it’s greatly appreciated.

When I gardened in Zone 6, I used to find that perennials I planted in fall got heaved from the ground during repeated freezing and thawing all winter, and I had to keep pushing them back into the ground. Freezing and thawing is also a problem with outdoor potted plants. With lavender - an evergreen - you have the additional problem of cold winds drying out the leaves while the roots are frozen. I would opt for keeping them potted indoors over winter - somewhere well lit, cooler than room temperature, but above freezing - and planting them out in spring. I'm not sure about the hardiness of the lavenders you bought, but I have a Lavandula angustifolia 'Nana' that survives (barely) in a sheltered spot in Zone 4, but it loses most of its leaves if not protected by snow-cover during cold spells.

Thank you very much for your help! If I keep them inside now, will they continue to grow or is it better for the plant to leave it out for the first hard frost and then bring them in a dormant condition.

Hardy lavender does not go truly dormant. As it has evergreen leaves, its roots remain active all winter, so don't let the soil in the pot completely dry out. If you keep it in a cool place, it won't grow much.
