I live in a temperate climate. I managed to keep my mango alive in ground for several years, but i have problem with flowering.
Basically flower induction works fine with low temperatures. By march i have my tree covered with flowers, but those flowers are often deformed because they grew in lower temperature.
Conventional wisdom wants then that i remove all the flowers to induce a second flowering with hopefully higher temperature; that's the tricky part; if i remove the flowers too soon i get the induction but flower opening happens too soon (May) and embryos are killed by low temperatures. If i remove flowers too late I would get the flower right when i want them (June) but then again, since the temperature in the meantime have risen, i don't get flower initiation, so i just get a growth flush.
So, I’m thinking about nitrate of potash to induce flowering, but i lack experience, knowledge, everything; by any chance, is there anyone who has used nitrate of potash on his mango with success, especially in a temperate climate? Do you have suggestion/doses/side effects?
