Well lack of growth might also be from pruning them at the end of last growing season. I guess I need to learn how and when to prune still. But yes, I did not get a lot of chill hours this winter, though my burgundy has a lot of blooms whereas my flavor grenade is only waking up on the single lonely branch.
The poor growth could just be a lack of water during summer. That’s what it looks like. On those trees no pruning is needed except to correct a badly unbalanced tree. You need more wood to ever get much of a crop.
My Flavor Grenade is also delayed and without a doubt due to lack of water this last summer. Just blooming, now, and not the most vigorous tree, but it looks better this year than last year. I bought some last year at our local Farmer’s Market and they were so good. Think they are very nicely suited to our N. San Diego county weather.
