Any suggestions on how to make it calm down until January or February when it can flower all it wants and try to set fruit?
Ok, Suggestions... Hmmm... Need a glass of wine... Ok, got it... ::: For those that Buy the Best Fertilizers:: Osmocote etc.... Good stuff Right as it lasts a long time 6Months or longer....
Well, maybe & maybe not... Depends on your needs.... If you applied it in June, Then count July, August, Sept, Oct., Nov., and Dec,..... It probably is still slowly releasing a little in Jan..... lol... Sooooo Just add water (rainfall) and watch those trees grow (and sometimes bloom with additional bloom stressors)... lol...
Some of the Home Depot fertilizers have made the nitrogen in sustained release also, I believe 3 months but maybe longer...
Just read the labels to determine when you want nitrogen to stimulate your tree growth....
If in doubt use cheap quick release toward the end of the normal mango growing season (July, Aug.,Sept., and definitely quick release in Oct. if you dare risk it.
But regardless, if enough rain and right temp. & other stimulators of bloom... There's probably plenty of nitrogen normally in the soil to help a few of the trees partially bloom
if the right bloom stressors are in place.
On your large fruiting trees, if fertilizer is needed... using quick release should lower your odds of out of season bloom... But it will still occur in a small percentage of trees IMO even if zero fertilizer is used, but the odds are lowered.
