where in Louisiana???

wouldn't we all be dead by now?

you can see it scrapes off with a fingernail, but the peel under it isn't right, its definitely affecting the peel...it still doesn't strike me as scab? nothing I searched came up looking like this.
the second picture is just cold damage from the winter, I think unrelated, but in the interest of full disclosure. my tree doesn't have canker anymore, but I do have leafminers, a little greasy spot im working on, and generally seems to be in decline. I had 500 fruit last year, and this year there is barely 100 on the tree, do they usually alternate produce?

edited....the more I look at the cold damage the more it bothers me that my tree is dying. if the bark is the most important part for transfer of nutrients, then I have a problem here, there isn't much left. it didn't get that cold last year compared to the year before, and I didn't cover it thinking it would be ok, but the rootstock obviously didn't like it...think I killed my tree?

what is this on my grapefruit?  you can see a few fruit that just look dirty, and one next to them in the background that's still green. this isn't dirt, or anything like sooty mold. whats causing this?

Millet, I think he is just very devoted to his cause...GMO is coming, it don't take a genius to figure that out. he seems to have more knowledge than the rest of us. don't you want to know what he knows? or is it all conspiracy theory?

I forgot to add, as you can see in the pics, the tree has a lot of competition. there is an azalea, mimosa, and other garbage within 5 feet of it. definitely in the root zone. that's why I ask if the soil or something else could be affecting its flavor.

don't try this at home, but the story goes, my mom planted a Satsuma seed and a lemon seed next to each other.  this is what came up

I CAN VOUCH FOR IT TO WORK.  ONE A DAY, AND CUT BACK ON SUGAR INTAKE AND CALORIES. WEIGHT DROPS QUICK. NOW IT MAY BE FLUID WEIGHT OR SOMETHING ELSE, BUT IF YOU NEED TO LOSE 10 LBS QUICK ID DO IT

sorry for the caps, didn't mean to yell

home grown clementines would certainly taste better, and fit what conditions you want, but their are better out there.  I haven't had very many others to be able to say good options...you look into a pixie or kishu mandarin?

Mark don't you think you should be able to paint it broadly? its the same ingredient in both, the numbers should add up close to the same if they use the same ratios. that's all Im curious about.  ive had someone pose a question to me, about the use of pesticides and whether they can poison a tree, and Im just trying to get better informed. if this stuff does sit in the ground for 7 or more years after its sprayed, that's a little scary.

I understand that Millet, I just believe the occasional ladybug dining on aphid gets killed in the crossfire.

what do you mean affected leaves? by the leafminers?  they shouldn't fall of the tree that easily, maybe you have something else going on with it

no gunnar this was a seed she planted, its either a Satsuma as she says, or a hybrid, or mixed up seeds...millet from what I remember, hadn't gotten any in a few years, these are tart enough to pucker you up, but had an underlying sweetness to them. I wouldn't call them off tasting, im the only one I know who likes them, but im weird like that...ill be going home in a week, and getting all I can from the tree, that's why im curious what it really is.

is it possible soil or other conditions are throwing off the flavor of a known fruit that badly???

yes we working on the grass problems. they were considering mulch, but im hoping it don't happen.  in 4 years they've never been fertilized.  but looking at the upside down orchard pic, some trees are doing fairly well considering that fact.  certainly not as well as mine at home that have been well fertilized, but they surviving...I cant believe the soil is that different in so many places to allow drought and nutrient problems...maybe I need to start digging, see whats going on under there.

you cant ship a pineapple to Louisiana? seriously? I know citrus is under quarantine but that's a bit much..
