Q: I was wondering when is the best time to plant peonies. What do you recommend I put in the hole with the dirt?
A: For best results, plant peonies in fall when daytime temperatures are reliably below 80 degrees. If you’ve already purchased one, plant immediately. Loosen a three foot wide area where you intend to plant one. Add a cubic foot of soil conditioner and thoroughly mix it with the existing soil. The result will be a slight mound. Plant the peony in the center after untangling and spreading the roots. Water thoroughly after planting and then once a week until air temperatures are below sixty degrees.
