South Florida Dot Mango blooming!

[paulmctigue]

My Dot is putting out blooms already. Seems pretty early to me but I'll take it

Nov / Dec bloom is normal. We've had a few nights with temps in the 60's which has inspired a lot of bloom.

My 2nd Julie and Ice Cream are pushing flowers.

Should I cut off some of the panicles, to make it bloom again to stretch out the harvest?

[beefyboy]

My lemon zest has just started blooming a few days ago and my Dot in my parents yard two doors over I noticed today, has longer spikes than my LZ.

I would not cut the panicles. Even if you could get it to re-flower in, say, February, the fruits produced by the Feb flowers would ripen a couple of weeks later than the Dec flowers. This is because during the cooler months, mango fruitlets grow extremely slowly.

Exactly

My Edward, Pina Colada, and the Lemon Zest portion of my topworked Young/Tebow are in similar stages of bloom.  It's a good thing, let them be.  Hopefully there will be a few early maturing fruit.

What should we be using on our mangoes that are flowering to push them along? Potassium Nitrate @ 1% v/v?

Seems like 4%.

I think that HI article is referring to the use of KNO3 to induce mango bloom, which is not effective at our latitude. I'm referring to the use of KNO3 to give the buds that are already going to emerge a boost. Now that we've had some nights in the 60's (which would induce bloom), it could be a good time to apply KNO3 to push them along.

There is an article that I posted a few days ago about that talks about this (I'll see if I can find it), but I'm not sure what the Floridian growers are using.

I tried KNO3 at 2% (mixed with keyplex) and got some leaf burn.

UPDATE:
Here's the article I was looking for: http://www.ctahr.hawaii.edu/oc/freepubs/pdf/HITAHR_04-06-93_54-60.pdf The last page speaks of a grower who uses a hormone to stimulate flowering conditions, then follows with KNO3 to force growth (which emerges as flowers). I wouldn't touch paclobutrazol (I think it builds up in the soil), but we could do something similar using low temps (nights in the 60's) to stimulate flowering conditions followed by a shot of KN03 to force growth. Seems like it's worth a shot.

I was also reading that KNO3 can cause the tree to hold more fruits.

I'm getting flowers on my Tebow/young, coconut cream, rosigold,  florigon,  lippens, rapoza, honey kiss, and pineapple pleasure. Nothing yet on my dot.

Great info thanks!

Ahh, your right. You are way ahead of me.
I'm still waiting for any tree to start pushing 

[greenman62]

My seedling grown tree is producing 2 panicles on 1 main branch / and branch-ette
and all the rest of the branches are actually putting out new growth !?

add to that... i just rained for 3 days straight
after 2 months of un-naturally dry weather

hope that new growth hardens before we get a freeze.
its supposed to get to 37F friday.

i am guessing the chance of fruit from those flowers is pretty low. ?
i hope it flowers again  later in the winter.

Ugly Betty, Nam Doc Mai, Dwarf Hawaiian and Cac are flowering in my yard.  Carrie seems next in line. Nothing on any of the others. UB was the first to flower, as was the case in 2015. The tree was covered with flowers last year but got hit badly by powdery mildew. Ended up with only 6 mangoes.

Would now be a good time to apply wettable sulfur (1 tbsp/gal)? Any issues with spraying the panicle directly at this stage of growth?

[Cookie Monster]

I haven't switched to sulfur yet. I'm still seeing anthracnose, so I think copper is still the most prudent; maybe wait til it cools down a bit before spraying sulfur. I would ask Har though...

How good is the Bonide Citrus, Fruit & Nut Orchard Spray Concentrate in treating powdery mildew? It is 10 percent sulfur. My Ugly Betty was badly hit by PM last year. I have wettable sulfur that I can use but I do not have the right sprayer. That stuff does not mix well with water.

[Cookie Monster]

Yes, that should work. The rate on the label seems a tad on the low side though. I might up the rate to maybe a cup of product per gallon of spray. (The sulfur product I use recommends a 6.4 ounces per gallon for mangoes and it's 50% sulfur.)

Side question since someone mentioned sulfur. If using ground water with high content sulfur and iron, should either of these ever need to be added? My newish neighbor across the street swears he doesn't have to add it and just sprays the trees with his water hose.

[Cookie Monster]

The product I use recommends 2.5% v/v (25,000 ppm) sulfur for mango.
