Watering 15 - 20 minutes per zone twice a week is fine and actually helps avoid splitting in the event of sudden rainfall during drought season. Just keep the water from hitting leaves / fruits. And be sure to adjust your watering to the weather. For example, you can almost cut out watering altogether during our "winter."

So what effect will running sprinklers have on mango production? I am trying to control the amount of water they get as to not to over water when fruiting. The grass has taken a hit the last 2 years, and pretty much scorched earth with beautiful mango trees LOL  Will using sprinkler system to irrigate grass 2-3 time a week screw up anything related to the mangoes?

Here some pics of my fathers VP tree. Planted from a 3 gallon around 4-5 years ago.
Don't know whats going on with it looks to be deficient in a few things. I think he might of spray some potassium on it a few months to a year ago.







Any ideas??

Here's a link from over at the phoenix fruit forum. The owner said that after the winter, the entire tree defoliated, but it wasn't because of the frost. The leaves turned dried green instead of the dried brown leaves characteristic of frost damage. The plant usually restarts from the base of the tree, which is the rootstock. I've also seen it happen before, so what do you think is the problem.

Dried green?  As in rapid dehydration in the shade?

My tree is show sign of the sap oozing out thru the trunk too and it's showing a bit of black color.  I am trying tea leaf oil on it to see if it will kill fungus that form the black color. Anyone try tea leaf oil before? I had a soar on my lip and it was getting bigger too, I applied tea leaf oil to it and it started to heal. I was thinking it might do the same for the tree trunk.

Sorry for the lack of pictures. Here's two of my trees showing a little bit of sap oozing out of the main trunk. This started in the middle of summer. The trees are growing fine. Flushing new leaves right now too.

We've dealt with this earlier in this thread.

Alternate sprays on whole tree about every two weeks with a phosphite product spray, and a couple weeks later with a copper product spray, until there are no more new indications of continuing problem.

My question is has anyone tried it with tea tree oil on the open wound  which is oozing out saps and will most likely be susceptible to fungus and later cause trunk disease like canker : https://www.flickr.com/photos/scotnelson/9603887230/in/album-72157632297340636/

Can anyone name this disease and prescribed cure for it? Branches have have spots with symptoms like snake shedding skin. It does seems to effect growth of the trees or vigor.

No, it's not in USA! I made a typo, should have said "does not seem to effect growth of the trees or vigor".  I've seen mature trees with this issue in vicinity, they all seem to be growing and producing fine. Placing all of my mango trees under perpetual quarantine than.

My Glenn is dropping a few leaves and is looking a bit sick.
The upper part of the tree is (not in photo) is full and looks healthy

(It looks a bit scraggly because i hollowed out the interior for better air flow this year)

Thanks Har.
If i water it and/or apply nitrogen now would that throw off any reproductive flushes?

You can give it some water now but if its mature enough and you want it to fruit, hold off on any nitrogen till after fruit harvest.  If it is extremely deficient of nitrogen, give fertilizer and sacrifice this season's fruit.

I water my trees (mangoes included) twice a week this time of the year. They appreciate consistent access to water. I just finished building out a sprinkler system for the neighboring lot :-).

That's caused by the larva of Mango Stem Miner (Spulerina isonoma), which is a moth.
It's a rare and minor pest. I have seen them a few times. A regular spray against the other major pests (flies, borers etc) should also control it.



Can anyone name this disease and prescribed cure for it? Branches have have spots with symptoms like snake shedding skin. It does seems to effect growth of the trees or vigor.

Looks like a red algae. 

You could probably clean most of it off with a 3/4-inch garden hose and water pistol;  then, after it dries, spray with copper.   

Other things that might work would be horticultural spray oil, or Organocide 3-in-1, followed by Biowash Plant Care sprayed with good pressure.

I have a Julie seedling experiment (growing it from seed to see what it produces), and the leaves look like it's affected by Anthracnose.  Could someone confirm and let me know the safest way to treat it?

Pictures a little too blurred when magnified....

On-line, look up "Thrips on mangos", look at the pictures, and then look at your mango's leaves with magnification, such as 8X, or a little higher.

Do they match?
