Summer pruning is your friend in California, but several times in the summer indicates to me that the gardeners don't actually know what kind of thing they are pruning. Especially since they wanted to prune off the fruit! Once when you're thinning the fruit to get rid of wild sporty sprouts, and then once when the tree is done and all the fruit is off is good. And thinning shouldn't be done by cutting off the twigs but by twisting off the fruit.

Apricots especially do not want to be spring pruned at all, because they bear fruit on the newest wood (I just relearned this and I think that's why I haven't had a heavy year lately).

The other fruits almost all bear on two or three year wood, so they like a bit of winter pruning.

In our area, anything in the rose family, if it thrives at all, must be summer pruned at least a bit or you will be living in Sleeping Beauty's castle in no time.
