Mango Pests, Diseases, and Nutritional Problems

Or possibly spider-mites, which you may need magnification to see.  There is probably no visible damage, right?

Twirl most of it off onto a stick, just before you spray hard with water.

Correct.  No visible damage and nothing visible inside the webs.  Knocked off most with a stick, then blasted all with the hose.  Seems to be a minor issue.  Appreciate the help.  Thank you.

I did several mango graft this season and got many good takes.
On one of the grafts, I recently took off the binding which was not expanding with the plant.  It had started to girdle it but I got it in time and the plant appears to have recovered (the compressed portion has increased in thickness to match the rest of the branch.)
I noticed a few days ago that some sap had oozed out at the graft location.  I am wondering if in expanding the back got cracked allowing something to infect the joint.  Has anyone observed this and is there anything I should do? 

The tree the graft is on is one I am top working.  The tree pushing new growth heavily and all over, including on the new grafts and the untrimmed parts of the original tree.  The tree looks very healthy other than this oozing sap which also is observed at one more graft location.  Other grafts on the tree look fine, the two with the sap had some stress.


The first had the wrapping left on too long on the graft. used to be thinner but you can hardly tell.  If I am going to lose this I can start prepping budwood from it to graft elsewhere.



The top of the graft on this broke in a wind event.  A small piece that was left had 2 buds, both pushed.  One has sap and the other does not.

Good morning my friends,

     I’m in need of some help and advice.  I have a couple of mango trees that I’m sure are in need of nutrients.  I have been following this thread to try to compare the symptoms on my trees to those of fellow members.
From the pictures I have seen,  and the advice I have read,  I can tell my trees are in need of nutrients and that there might be some other issues.
I water every 3 to 4 days with city water,  recently added a bit of epsom per recommended dosage as well as a bit of sulfur also per recommended dosage.
Some help and advice will be appreciated.  What nutrients does one recommend.
These pictures were taken this morning
Pictures 1 and 4 same tree- Manila seedling in 5 gallon pot
Pictures 5 and 6 are lemon zest in 7 gallon pot
Pictures 2,3,7and 8 are coconut cream in 25 gallon pot

Forgot to mention that I also have other mango trees that don’t have these issues.
2 - OS on terpentine
1- keit
1- pineapple pleasure grafted onto Manila
1- PPK
1- ST
1- peach cobbler grafted onto a Keitt
1- peach cobbler grafted onto corriente
As welll as several Manila and corriente seedlings that I plan to use for rootstock.
All are doing well.

Spray new growth with a full micronutrient mix plus extra Copper, per labels, to correct deficiencies of Copper, Zinc, Iron and Manganese, and to suppress Powdery Mildew.
