The time for trimming is still ok, Mike. As soon as we get the real summer rains the plants will put on a lot of new growth and that is not really the best time, unless you can take cuttings that still have grey wood. The green ones will be the most likely to rot on you.
Unfortunately a lot of people want their trees trimmed in August/September, and I still do it, but you just have to count on a lot more loss then.
