I have containerised garnet and seiryu maples and for consecutive seasons it would appear that a significant proportion of buds on each plant will not open.
These buds turn brown and die.
In the case of the seiryu the problem is particulary with terminal buds but not confined to .
After experiencing this last season I eventually cut off the dead branch parts. If I have to carry out a similar procedure I will begin to have plants that look stunted.
What causes this and is there anything that I can do to resolve the problem?
