Judy--
I have not sold any potted siberians, but I have potted them in
spring and overwintered them until the following spring and fall
for planting.
I use gallon or larger nursery cans, and a mixture of 2/3 bagged
topsoil and 1/3 peat. I plant the siberian in the pot with the "toe"
closer to the rim of the pot to allow for increase space. I top off the
pot with about 3/4 inch of sand to help retain moisture.
They are kept watered thru summer and fall, and when late fall
arrives, they go into a cold frame or the pots are planted to within
about 3/4 inch of the rim. If I plant the pots, they also get a nice
mulch of pine needles or hardwood mulch.
The pots from the cold frame are usually advanced in growth, and the
lid must be propped open when temps start hitting mid-50s to help
harden them off and prevent them from cooking on an extra warm day.
I usually give them a couple of weak doses of miracid after active growth
begins. Many of the potted sibs bloom in their first spring while still in the
pots. I have only had minimal losses with this method, perhaps 3% or
less on several hundred pots over the last 5 years.
I live in SW Ohio near Cincinnati, zone 5b. Temps below zero are not
unusual during the winter. I hope this helps!
