Thank you Har,

I will also be getting a soil test from the local extension office to see what the soil looks like.

Weed killer was applied a few months ago and that could also be one of the issues, although it wasn't very close to the tree.

Does anyone have any experience with R-K Nematodes and mangoes?

So was this a "weed and feed" granular application to the grass around the tree?
What exact weed killer was applied, was it even close to the drip line of the tree?

Had a lot of this last season, too. I can't figure out if this is Powdery Mildew or spiders. There are a fair number of spiders/webs in my trees, but it also seems like when the PM starts getting really bad, small web-like strands (almost cocoons) form around the hardest hit panicles. Does PM progress to a stage where it forms something like this?

Spiders or spider-mites or webworms.

If you are foliage feeding micronutrients to mango trees, how frequently should it be done?  I have used Cal-Mag Plus. Any recommendations as to other micronutrient sources?

Thanks Har, I did notice some caterpillar-like creatures yesterday on a panicle.
I do think these webs promote the PM (to some extent); they keep old buds from falling away and form little clusters/pockets of dead matter on the panicles. I'm going to take a magnifying glass out there today and see if I can figure out what bug is at work here.

Har, I believe you warn people about adding compost when planting a mango tree even in very sandy, very poor high ph soil, can you say the same about peat please?

In soil mixes, 10% peat is great (up to 20%)  (by volume).

Har, any thought about using coco coir?

Can I use 10% peat in the planting hole during the last transplant in ground?

No decomposable ammendment is likely to improve planting holes for mangos--- way likelier to sicken.

What about the compost for mango trees, can we use it as a mulch? if not is it beneficial for 3 feet seedlings to till it around the tree?
Thank you in advance for the answer

I put pruned (and cut into straight sections) branches (less than 1 inch diameter of wood) and fallen leaves on the ground under fruit trees of any kind.

Newbie here and just moved to Tampa not very long. I have this mango for 2 months and I notice black leaves as in pictures. Should it be a concern and what to use to eliminate this?
Thanks!

Tonyma,
First photo may be of a slight excess of fertilizer, especially of urea.
Second may be a little anthracnose.

No big worries so far.

I have little black spots and pitting and apparently a leaf-hopper on my Neelam seedling leaves. Admittedly it's not in the best spot, getting a bit of shade throughout the day from an oak, and probably has restricted airflow too. I couldn't help but plant it, though, because I just can't stop.

Interesting.  I have never seen leafhoppers bothering mangos.  I don't know what the pits are from--- maybe the leafhopper?

In the lower part of the picture are two angular black spots;  maybe Mango Bacterial Black Spot.

Thanks, Har! I erroneously thought Neelams weren't susceptible to MBBS (though this is a seedling whose leaves smell like Neelam). Perhaps the leaf hopper was just resting on the leaf? Thanks!

I don't know of any variety that doesn't get MBBS sometimes.

I had scale and what was believed to be powdery mildew causing browning leaves.
I wanted to avoid copper and sulfur, what with all their caveats, so I foolishly sprayed with Neem oil and potassium bicarbonate on all 7 trees for 8 weekly treatments on leaf tops and bottoms.
This killed the scale, but the browning and dropping of leaves has only continued, previously unaffected trees are now affected, and new growth is affected.

Orange Essence is not as badly affected as some others, but the leaf coloration looks suspect.
Not sure if I should just go with sulfur or copper or if it is too late for these trees.

Thanks

I just purchased an ice cream mango that has some new growth and flowering. I watched Har's video and he mentioned that i would lose new growth when transplanting into the ground. Is this to say i need to wait until winter or fall to plant him? Its currently in a 30 gallon pot. There also seems to be some black spotting and white spots.  See images

Go ahead and plant.  On a tree with that many branch tips, there will almost always be some new growth somewhere.

DM,
What kind of soil were those mangos planted in?
