1- Are flower buds formed or yet to be formed?
2- The buds in pictures are flowers buds or growth buds?
3- Regarding pruning, you can see this vine growth is mostly vertical and not much side shoots. It blooms on old wood i have read. Is it necessary to prune it now?
4- I have GA-3 and i read that it can promote flowering. So can i try GA-3 on it to trigger flowering? i use foliar spray of GA-3 but the foliage is almost dying now.
As you can see the trunk is very thick and stems are old and fat.
