My liquidambar, about 10 feet high and until now very healthy, has only come back partially this spring. Few leaves on the bottom half, not too bad on top but the growth seems weaker than usual. I had thought it was b/c it is in a large pot and the relatively cold winter was hard on it.
However, I just drove by a shopping centre here in the Fraser Valley and in its parking lot most of the larger, better established liquidambar are showing the same signs. In fact, some appear to have few leaves, in one or two cases, even no leaves.
Does anyone have any ideas as to what might be the problem?
