Should I stop the nitrogen on my mangoes now?
« on: September 05, 2023, 10:28:29 AM »
The last time I applied any fertilizer to my Maha and Glen trees was in March 2023. They've grown magnificently, the Maha (below) started out 2 1/2 years ago at 3', and is now about 8-9' high by about that much wide. There is a pine bark mulch surrounding it and my lawn mower throws clippings on top of that. I really want a great fruiting season for next year so I don't want to mess it up with too much fertilizer. I'm thinking should apply something that doesn't have nitrogen but not sure about the best analysis to use. Is the pine bark providing nitrogen? Any help is appreciated.

The tree leaves looks dark green to me. I wouldn't give any fertilizer anymore this year.
Depending on the weather it could flush late and not have flowers next year on the new growth.
I have a couple larger mango trees and I don't fertilize them at all.  I do give  my young mangos
8-4-8. My neighbor gave his large Lancetilla and Angie fertilizer non stop last year and the leaves
are super dark green and not one flower this year.

I would not give them any nitrogen, unless you're wanting them to get big quickly. Be careful not to feed the grass with nitrogen too close to the root zone either.

There is a special 0-3-16 formulation that Har / Guanabanus helped create which is sold by Truly Tropical and is perfect for mangoes on our sandy soil: https://www.themangoplace.com/fertilizers

Yes the foliage is dark green and I can't find even one brown spot anywhere on the leaves. It's so green it looks fake.

I don't fertilize the lawn so I'm safe there. I'll have to look around for something similar to that 0-3-16 because Truly Tropical doesn't ship. Thanks

Bone meal has little nitrogen and high phosphorus. Sulfate of potash gets you the potassium. I mix these and use around my mango’s.  For plants that like some nitrogen, add some blood meal to the mix.
