Seedlings that show these symptoms are already goners. I suggest you sprout the rest using the ziploc method. Wrap the seeds in moist paper towels (not wet!), put the whole thing in a ziploc bag or anything similar that would seal in the moisture, and put the bag on a heat mat or somewhere warm. After 1 week, check every 2-3 days so as to catch the seeds when they just start to pop open and sow them or else the roots will curl up and it will be a crap shoot when you sow.
And when you sow the seeds, keep the soil moist but not wet and NO fertilizer until you get at least to the 2nd/3rd flush of leaves. These steps work well for me.

@Cgameprogrammer. Majority of all my trees are mail order from Florida. Only trees I have grafted myself is an Alphonso, NDM, and one of the Mahachanoks. Good luck with your trees.

So, I suppose they are on turpentine rootstocks and growing very well at your place. If that's the case, we might be trashing turpentine as rootstock in So Cal for nothing...

Should I start fertilizeing ?

I would test the soil pH first to make sure it's not way too high to prevent correct uptake of already available nutrients.

I'm aware of mango seeds not allowed allowed but scions were. I got my permit 2 years ago when scions were still allowed. But now they just decided that anything Mangifera is not authorized. Another change is that the site inspection is no longer free.

Finding longkongs would be enough for me. Along with langsats and other dukus, they are top on my list of all time great. My own personal taste, of course.

I grafted a Giant Mexican Sugar Apple onto a Cherimoya rootstock and I noticed this liquid oozing out of the tape

This is most probably a problem of overpowering sap flow. I have had this many times before and reported it on below thread.

I don't know if the orchard is open to public or not. Peter is a well known cherimoyas grower and seller on this forum. Contact him and if he's not swamped and you're not rude, he will reply.

Warren is correct. Flower buds on my grafted Ah Ping started a week ago and now it looks like LZ's turn.

No weather (rain or frost) damage or washout on this 2 pounder...

Something tells me you got a nice surprise from Peter too, Rob. And don't know about you, but I think Peter has a better crop this year compared to last year in terms of quality.

I spit out Nata and Santa Rosa.
...

This year Peter's Santa Rosa is up there with El Bumpo and Pierce in terms of taste and size. It has a perfect balance of sweet and tart with a little bit of chewy texture that I personally like. This is also my first Santa Rosa over 1 lb. Growing condition and timely picking matter.

Just got nice surprise from Peter, a giant Pierce. This should compensate for not being able to go to the SCREC tasting this Friday.

Here are a couple of crosses with the Lottery results in 2 years hopefully. Notice the difference in leaves forms depending on which is the mother tree.

47-18 x PM (from JF).


PM x 47-28 (me). Some iron/sulfur deficiencies here and the current rains don't really help.
