SF bay area Mango growing
Twice since 2007 I have grown a Mango to fruiting..and twice the very next winter it was killed far back by frosts..frosts it had stood up to the previous years. 2007 was very cold..but last year was just one night of 32f. In 2007,it was a Manila,last year the Bailey's Mango. I totally lost the graft of the Baileys..it's now all the Haden(?) rootstock and 3' bushy feet tall. From 7' last summer to 3' this summer..and I was glad it didn't die period.
My advice to fellow Bay Arean Mango people is too not allow a young tree to bear fruit..it WILL WEAKEN them the following winter. If your tree looks too small to hold a few Mangos? It probably is. Try to get more foliage growth before fruting.
I'm not pruning the rootstock plant since even now its flushing..I will only prune the day it gets too big!..if that day ever comes-lol.
