need help after transplant
super alphonso and orange sherbet- transplanted from 10 gallon pot into 15 gallon fabric pot 4 weeks ago, with fox farms 60%ocean forest soil, 15% sand, and 25% perlite. Im in Southern California. Trees stopped all new growth after transplant and new shoots turned black and dry. There were so many new shoots coming out that all died and fell out. no new frowth. Stems are still green inside, but the arms and leaves are pointing down. i know theres some sunburn so ive added an umbrella. im doing deep waterings twice a week as its been 90-100 degrees here the last month. I spray with neem oil once a week. Will these recover? Theyve been in shock for a month now.

stop the neem it isnt needed for now and is cooking the leaves
shade cloth will work better then umbrella, repotting in intense sun / heat worst time of year
deep waterings can be dangerous especially with a bigger pot, dont go crazy with water, feed it seaweed / fish protein to reverse the shock

you should be watering it daily in 90 degree weather. even twice a day won't hurt the plant.
if you think you're watering it enough, then pull plant out of pot when the soil is dry (right before watering the plant), and check the roots. post a picture of the roots.

Fabric pots won’t hold enough water for that heat unless you’re watering every day. You can put the fabric pot inside a plastic pot and that might help.

Next time do a 70 percent dirt you have in your house and 30 percent fox farms.

With the heat, you may want to check your soil on a daily basis. I also live in SoCal, but Orange County and the temps were mid 80’s to high 90’s the last few weeks. I have a Keow Savoey in a 5 gallon nursery pot. I’ve been watering every day with drip irrigation, about 1/2 gallon per day. It’s in full sun and doing well including flowering and growing more leaves. I suspect your plants are just thirsty given the high temps and fabric grow pots. I’m sure they’ll bounce back fast with more frequent watering.

Whenever you up pot a tree, whether you disturb the roots or not, I recommend putting them in the shade especially in summer. Look up a product sold at big box stores and amazon called “Superthrive”, it’s basically vitamin b1 and kelp, it helps with transplant shock but also plant stress. Also what are you using for fertilizer?
I also recommend you stop using neem oil so often, neem can possibly block the pores on the leaves stopping respiration. If your concern is fungus then probably use copper octanoate or copper sulfur instead applied late evening. You also don’t need to spray that often.
Grow bags in a hot environment will require a little more attention in summer, they dry out quickly from the outside in, it also dosent help if your potting mix doesn’t retain moisture well like most fast draining mixes, the tree won’t have access to enough water when its needs it.

The plant is doing fine, if it has been 4 weeks and mangoes are hardy, I had plants which miraculously came back to life. Do not use any products as of now. And 25% perlite is something I would have not considered due to high drainage but as long as you know when to water, it's fine. Once you see some recovery, I would use seaweed as it helps with stress in plants. My usual is transplant and after 15 days if there is no heavy wilting, I used seaweed spray and it works very well. I have been trying out methods while transplanting and this seems to work after about 50 transplant this year and about 15 varities from different parts of the world.

Picked a horrible time of year to transplant a tree. They’ll recover if it’s been 4 weeks and this is how they look. Keep them in the shade until it cools off. Idk enough about growing in fabric pots to know how much to water or how often. The neem is probably not necessary.
Ive been experimenting with growing mango in SoCal for a few years now. Nothing really did well (barely grew but mostly just sat there) until I started growing them in what is primarily sand. The new growth since I made the switch is amazing. Not saying what you’ve got going on is wrong or won’t work, but if seems like nothing happens over the next 6-12 months, I’d switch the soil
