Sorry Joe, I was confused. I have the same question for those in Southern California. Because we are in similar climate, how long should one wait for grafts that are made outdoors on matured trees? I hate to say that even my apple, apricot, plums, pear are sucking bad with just hint of new growth starting while I see big box stores and some others around where I live lush and green. My Longan is in full swing loaded with flowers, but lychee wants to die, just ordered rooting hormone to save it.
