Mango: 2023 SoCal mango start flowering

[sapote]

Most of my trees start to send out flower stokes on Dec 1st 2022 -- much early than normal. Too bad as I will only let the fruitlets hold after March. I think reason is those trees didn't have flowers or fruits this year and they are busted with energy.

Same for your trees?

My smaller trees are flushing with vegetative growth but I heavily fertilize last month hoping for leaves over flowers.  I don't know if it's the weather or not as it seem others been getting lots of vegetative growth also.

My larger trees, I did not fertilize. They don't appear to be doing anything at the moment.

My franken Manila has started to bloom also for 3 weeks now and I've been spraying sulfur once a week since then. I'm determined to get some fruits this coming season. Powdery mildew has been wrecking havoc for the last 2 years.
The tree is 16 years old but no that tall.

It may not solve all of the issues, but one method that has been suggested is continually removing panicles to stimulate rebloom only allowing the blooms that form after the final rain of the winter season to remain. The idea being that the stimulated reblooms should form sometime after the final propagating event for the PM. That said, it may not work if the tree is planted in an area that receives significant morning dew. Only the most inland valleys have a chance to really avoid the mist, or east facing slopes far inland. For the most part the sulfur sprays may be the answer, though I've read skim milk preparations work as well.

I don't know if the cold weather, or PM, that caused the fruits to have no developed seed and then they all cracked and fell off. This is the reason why I only let the trees hold fruits after March/April.

My problem, at my location, is powdery mildew. No fruit or 2-3 from a lucky variety for the last 2 years. I'm trying to change this with sulfur spray.

My in ground  sweet tart(on atulfo rootstock) started to flower. All others growing vegetatively. Quite interesting that it still had hanging fruit and started flowering. I will not let the first bloom flush fruit since it always gets PM  early on.

wow, more than 3 months since I reported of the flower panicles on the trees, and now here they are still with flower buds not open yet. The cold weather slow down the flower development, I think. So far no bad sign of PM yet. I hope the buds will fully open for the bees in March and it should be warmer by then. I also think we only have the best wind from March to early May, before the marine layer moving in causing morning dews in warm weather and it a good recipe for PM. Took this pic this morning on LZ + O-krung tong grafted on HD mexican rootstock:

16 yrs old grafted tree planted when it's 2 ft tall? Young grafted tree takes forever to grow.

I got about over 2 dozen varieties blooming right now but since most were grafts from last year I don't intend to let the fruit mature.

But my larger trees are blooming quite a bit. I have 3 mature trees blooming(nameless seedling). Hoping for a good year.

I like those big box store Manila as rootstocks. They grow vast and vigorous but they seem to be very powdery mildew prone and carriers for PD that seems to spread to everything else year round.  Luckily my large trees are now are mostly a variety that is very resistant to PD even though it's a nameless seedling.

The cold weather in soCal this year delay all of my mango flower buds from opening and they are blacken. The pic in my post #7 of Feb 18 with all the flower buds and none have opened. How is everyone's mango flower condition?

Yeah, same here. Anthracnose has kicked in on all my Mango's. I don't spray, so I'll just let them grow out of it and probably do a hard prune this year to strengthen the branches. My tree isn't nearly as large as yours though.

Same here, lots of blacken disease blooms. Some still look like it has a chance.  I have about 30 varieties grafted on 8 trees on one plot, everything began to flush and bloom a while ago except for 2 varieties, Maha Chanok and Bombay, they are just beginning to flush which I thought was strange but a good thing as it would miss our cooler weather and rain and maybe even the peak powdery mildew season.  My other Maha on another plot has just barely beginning to flush also.  Has your Maha bloom?

[sapote]

  Has your Maha bloom?

All mature trees sent out flower stems back in January, including Maha. However the younger seedlings (2.5" or larger trunk) just sent out now. I believe the trees that didn't have much fruits last year tend to send out flower earlier, and those that had more fruits last year are starting to have flower buds now.
Will see after this cold week if the weather not warm up fast, then I might pick off all of the old flowers to stimulate a new ones.
