Don’t plan to plant anything, even trees and shrubs, where roots will be in the area that will be driven on. Soil compaction from vehicles (which means poor drainage will result and other problems) is not favorable to plants growing, period.
I have some herbaceous peonies that I planted 3 years ago. they come up every year, but never really fill out, and I have yet to see one flowerbud or flower. they’re in full sun, and get plenty of water. what am I missing?
peonies are very picky about their planting depth. It’s about the only time I take a ruler out to the garden and make sure that the growing points are 2 inches deep.
I agree about the planting depth. If even the foliage doesn’t look filled in and happy, they are likely planted too deep.
And they also do not like their ‘crowns’ covered at all (related to planting depth, I suspect). If you mulch deeply around them be sure to *not* mulch close to the plant. Leave at least three inches of bare-ish soil around the cluster of stems.
This old post on the blog, When the Normally Tough Peony Fails to Bloom, has a bunch of tips related to this topic. Hope it helps.
you guys are fantastic! thanks for the advice. I think I must have planted them too deeply. maybe next year I’ll have flowers!
I have an urgent question. I was given a tree peony “stub” late last fall, and as I could not plant it in time, heeled it into a pot. Miraculously, it survived. Now that I want to plant it, I cannot find specific enough advice. This is a cheapo-cheapo, just a cigar sticking up from the graft. The top has two big buds that are now growing. Below on this stem are 4 fleshy buds, tight against the stem, that are not sprouting. The question is, do I bury the plant up to the sprouting branches? Or, if it is too late to plant out this tree peony, what’s the best way to pot it up until it returns to dormancy and I can get it into the ground?
The graft union must be below the soil line, says peony expert and nurseryman Roy Klehm. He says:
“The graft of the woody stem (scion) and the root (understock) is very sensitive. The graft should be well below the soil line so the plant can eventually develop its own root system and no longer depend on the rootstock to which it has been grafted.”
