My mango tree is flowering but not fruiting. It has been infested with sooty mold but is getting better. The flowers look black after a few days and there are no fruitlets. What should I do?

Okay, so perhaps I’m stubborn in trying to get a mango to grow here that was clearly unsuccessful the first time around. But to my defense I didn’t know if the first issue was user error or a product of location. The exact same issue occurred previously. A seemingly healthy, young grafted keitt is planted (this time it lasted an entire year), then at the start of summer it’s leaves start to droop, it’s branches from the growing top downward start wrinkling, and it eventually dies. Upon inspection both trees had tons of either palm roots, privet roots or jasmine roots completely intertwined in its own root ball. I have a healthy seedling growing at the base of another queen so I don’t believe it’s the queen palm.

Anyway, the jasmines are my neighbor’s, planted directly behind my mango and the privet is about 40 ft tall planted about 15 feet to its right. Here are some attached photos. Last time this happened I pulled it out and brought it inside, copper fungicide drenched it’s roots and then watched it die. What can I do to save it?

Is this too much competition and lack of water? It gets a lot of water but it’s area is never soggy.

DScotM,

The base of the tree looks as though it was slapped by a weedeater.

Jaboticaba45,

Have you had your soil analyzed, or your mango leaves analyzed, by a lab?

Have you applied Calcium and a full mixed fertilizer, with all the micronutrients?

Do you have plenty of flies or bees, to do the pollination?

Looks like rabbits girdled it.

You can try to repair it by bridge grafting.

Thanks but I don’t believe it is girdled. The bark has always looked that way and nothing ever damaged it

Guanabanus,
I have not had my soil analyzed or leaves by a lab. I have just started to fertilize it with 8-3-9 because I didn't have fertilizer before, and there are plenty of insects I see on the flowers.

I recommend that you get granular gypsum, and apply 1/4 as much as you apply of 8-3-9, each time you fertilize.

Hi all, i noticed a black spot on a branch of my mango seedling (unknown cultivar). The spot is exactly on the same area where there was a contact with a leaf from a second branch (the leaf was stuck against the nearby branch at a leaf node so when i displaced the leaf i found the spot and the leaf node fell, as if the prolonged contact and humidity enduced the black spot, but i am not sure if it is the case or juste a coincidence).

Should i worry about this spot? in that case should i cut the whole branch to avoid spreading to the whole tree (it is the smaller one of the 2 future main scaffold branches,the one oriented to the right).
If there is no worry about it i will leave the branch.

Here are some pics with a closeup on the spot :

Pruning it off would be easiest.

Or you could apply a Bordeaux paste (lime and Copper Sulfate, or simply spray with Copper Sulfate or with a "liquid Copper."

My Maha acquired an infection like that earlier this year. I pruned heavily to try to save it, but it killed the tree.

Hi all, today i cut the branch and i share here more detailed pics of the inside of the branch (a cut at the injured portion), may be it will be useful to future readers.
Apparently the black spot was limited to the bark. It also did not extend to an area out of the visible black spot. I cut the branch at the base and it was clean.
@ Oolie: I hope that the infection that killed your tree was more extended than my case (sorry for the loss by the way)

That infection is all the way to the cambium layer, so it is not just superficial.  You did well to prune.  I hope you sanitized your clippers after cutting into the infected area.

Ah ok, thank you for the clarification and for your initial advice.
I cut the whole branch from the base as the first cut in order to avoid spreading any infection. then i started to explore the cut branch and take the pics away from the tree. And yes i sanitized the clippers afterwards as well for future utilizations.
Best regards

It is better to do it this way to avoid spreading the infection.

Though in my case it did not appear to have spread from the surface, but the cambium was already infected down to the trunk, even though it was not evident from the bark. In other words I caught it too late though it looked very similar to yours. Cross your fingers.

So I just found out that my mango trees have anthracnose. There were tiny black dots on the flower panicles. I sprayed them both with neem oil. Any other recommendations? I sprayed the flower panicles with it too. Is there any chance of fruit set?

Hello everyone! I nead an advice. My small haden mango tree is sprouting new gowths near the base. She is not grafted. I should take them off or let her develop lower branching?

While this is neither a desease not a nutritional problem, I say take it off.  THere is too low when it comes to branching.  Your branch and any fruits will be on the ground when and if it fruits.

As your plant is not grafted, it is not a 'Haden.'  It is a "Haden seedling."  It is a new variety, which may or may not resemble a 'Haden.'  If it proves to be good, you can put your own name on it.
