One of my Emperor Lychees grafted onto seedling rootstock was knocked over and dried out. The other one was planted at the orchard at Brads place and unfortunately it was flowering last time I checked up on it. I’ll check out how it’s doing if it’s still alive.
One lesson I learned from these experiments is that micro grafted trees suck because they have such a small root system that they grow relatively slow. Combine this with the fact that I grafted with mature scions and you get a similar result, similar to Mangos, early flowering that unnecessarily wastes stored energy that ultimately stalls vegetative growth.
It is best to grow out the rootstocks to as large as you can reasonably grow before grafting it with mature scions. Grafting Lychees in SoCal should follow the same same rules as grafting Mangos and White Sapote. So far, I have found that grafting these three varieties of fruit on young rootstocks will actually inhibit vegetative growth.
