Here is the tree peony that I planted in the pot: Hanakisoi. I got this in a pot at a Nursery marked down in October.
Here it is in the top of the pot with its roots sprinkled with mycorrhizae.
Here it is completely covered except for the tip of the uppermost bud. The reason I planted it that way is that you can see that it is a graft, with not a lot of TP stem growing above it. I want roots to form on the TP stem. I found this lucky rock down at the Creek and put it on top on the soil.
I may cover this pot up whenever we are expecting heavy rains. I am concerned that it may rot in our mild, wet, winters here. On the other hand, growing above the ground will let it get more chill days! It will be a fun experiment, and I will continue to post updates.
