Why does tree peony cuttings not shoot up?

15 years ago

I moved 20 tree peony cuttings back to my hometown 2 months before. All these cuttings have some new roots while moved.

Yesterday, I called my father. He told me that all the tree peony cuttings looks fine, the sprouts are fresh, but nearly no change at all compared with 2 months before,no shoot up,let alone leafs.

Its warm there in my hometown, the air temperature is about 70F (20C). Some of the local tree peonies are blooming. There must be something wrong with those cuttings, I don't know.

I also kept several rooted cuttings in my room, these cuttings also not shoot up, just like those in my hometown. The tree peony here just shoot up several days before.Here is zone 7, my hometown is zone 10. All of these cuttings are cut from zone 7 in the last autumn.

I guess,if this problem has something to do with dormancy. Cause before transplant, all the cuttings were put in a warm and humid place in the last winter, the air temperature is 70F with a humidity of 70~80%.

Without leafs, these cutting will die after all the stored nutrition exhausted.

I plan to try some hormone like GA3 to do with dormancy. Any suggestion for this?

Give them time. A guess on my part is that they are still on their home area's time schedule. Another possibiliy is that although the air temperature is warm the pot temperature is not.

I love the glaze on the pot in the second picture. Please do not tell me it is plastic. When I get really old I would like to make pots and experiment with glazes.

Yes, I have to wait, wait them to shoot up. But even according to the home area's time schedule, they are late.
Are there anything I can do to help them shoot up? Some guys said, it might be short of nutrition.If this is case, what I can do? Are there any kind of fertilizer that could supply nutrition to the cuttings?
ps, maifleur,actually, it is plastic bottle,sorry.

I just made a nutrient solution,with grape sugar, Vitamin B and C. Find some medical gauze, dip in the nutrient solution, and wrap on the cutting stem.
Maybe this might help to supply some nutrition to the cuttings.

Whimper, whimper. That color would make a wonderful pot.

Keep us posted with your progress.

A good news: I just remembered that the glaze in the second pic is not plastic.
Actually it is steel wire coils under a close up lense. There is a steel wire bed behind the plastic pot. You can also find it in the first pic.

I am now trying to supply some nutrition to the weak cuttings, I hope it would work

I just read a paper in Chinese. They made some experiment with tree peony in warm south areas of China. The tree peonies have not shoot up all through Oct to May, under the temperature of 16~18c(64F).
If this is the case, then I'd use GA3 to force through dormancy.
