I posted this on the GW but i'll try here too. Late last summer I planted a Haden Mango and it has done well so far. It's groown about a foot since I bought it! It has now begun flowering and the flowers are so heavy that the small grafted stems are having trouble supporting them in the rain. I had to support the heavy one with a long stake and twine. Isn't the plant to young to be flowering so heavy? Am I supposed to trim or prune or something?
