I would cut the trees down and plant 3 Tommy Atinks in their place.

Manganese deficiency.
Thanks Har! although there is some manganese in the brandt biomaster it may not be enough to correct the problem by itself?? maybe I should ad a manganese chelate to the regimen for these trees..

What are you watering with? Well water? Maybe sacrifice the sod for mangoes.

I've been using city water until I get my irrigation pumped replaced..usually it draws from the canal behind the house

City water tends to be very alkaline and contains chlorine. I think that's your problem.

yah, unless you have some unique soil situation, you should have deep sand (~neutral ph) in boynton beach. So, the manganese deficiency would presumably be from an alkaline water source.

I completely nixed (mulched over) about 90% of my grass and turned off all irrigation (both to the chagrin of the homeowner's association :-). The little patch of grass in the front yard starts looking brown during the spring, but my mangoes are happy, and that's all that counts ;-).

I think that is PM, powdery mildew, on your flowers. If so copper sulfate spray should help.

Others could speak to this better,  but I think that it takes a good while for the leaves to show improvement, after you apply minerals. I'm not even sure that the older leaves will always improve.

I was wondering this myself...maybe only the new growth shows the improvement?

Can someone please help me identify the problem with my mango.

There are these  burnt scaring appearing on my mango tree leaves.

Tomatayo and keitt mango leaves.

Is there a solution for this problem?

Bad water - just my guess. At least it still looks good and not dying. ;)

I would say salty water as well. We in Phoenix know what that's about.

I think I have an answer to my own problem and I think it's fertilizer burn.

You know moderators.

You should consider havering certain subjects as a sticky so people don't have to search for it.

I.e. fruit diseases and in the subcategory have mango, orange, longan....etc...

Have you sprayed lately, such as with oil or soap?  It looks as though something settled on the lower parts, dips, of the leaves.

No no spraying oil or soap.

I did fertilize it with hydroponic nutrients.

I've seen fertilizer burn before and they generally start at the leaf tip and move inward but not in sections like this.  Most of the main Vaines are undamaged.


It's either fertilizer burn that I have not seen before or it's sun burn.

I don't know what else.

Anyone?

This is a sad story but I planted some mango trees at my Dad's house and they were doing fine until I left to study abroad. Since the 2 years I have been gone 4 trees have died and the 2 trees shown below will be the fifth and sixth if I can't figure out how to save them. The trees seem to be doing fine, then some just suddenly get stiff leaves that continue to shrivel up and fall off, plus turning either red (like rust) or showing large black and gray spots, with the tree eventually dying. He lives about 3/4 mile from the ocean, and in an old avocado grove, so the soil is sandy, good draining "brown sugar".  I don't think  they are overwatered since they were watered about every 10 days this winter when it has been sunny and hot, and about every 2-3 weeks when it has been cool.  There is a gopher problem, but the trees were planted in 1" poultry net baskets. The trees have been sprayed several times--first with greenlight fruit tree spray, then neem oil, then finally with Captain Jack dead bug, and he's about to try copper fungicide. I don't know what advice to give him since I am thousands of miles away, can anyone please help?

Looks like salts/fertilizer burn, or possibly burn from neem oil on the plant. Might be an issue of doing too much to the trees and poor quality water. The trees don't look like they may survive, if they do I am sure the trees will be stunted.
Grow mainly fruits, vegetables, and herbs.

I agree it seems like fertilizer burn in combination with neem oil burn.  I didn't recommend all the chemicals I think he panicked when the trees started to decline. The trees are pretty much gonners  :( I just suggested to water the trees more often like 1-2 times per week and make sure there is a 6in think layer of mulch with a 2-3ft radius around the trunk of the tree. Also give the trees some fish fertilizer every other week. Is there anything else that could help at this point?

Yup agree, looks like fertilizer burn, or something with the roots. Did you gradually adapt the tree to full sun? Also, newly planted young trees may need more frequent waterings during the establishment period. Did your dad happen to let any of the trees hold fruit?

Simon,

None of the trees held fruit. I am baffled at how these trees keep dying. I was home for Christmas and they looked healthy and were pushing growth. I am shocked to see the condition they are in now and am trying to figure out how it happened.
