I bought 2 distictus laxiflora a year and a half ago. Planted in some big containers and trained over the garage door first year. No blooms, but a fair amount of growth. Didn't prune. This year there is very little foliage and it looks pathetic. I don't think it's due to pests. Should I have pruned it last fall? I'm in southern california. If anyone can offer advice, I'd be grateful.
