All of them started to shoot during spring. but 2 of them have only developed this small Fuzz rather than full shoots and leaves.
any ideas why?
They were all potted at the same time, Same soil mix, Same fert and watering?
One of the trees is collected a few years ago and was fine last year, the small one has been on my bench for about 5 years with no issue, and I have another larger collected one that is fine

Thoughts?
