It is October and my trees have fruit. What should I feed them now? I have not been caring for them until now, after the storm ISAAIC. I have six trees and planning to add more trees. Will use Nitrogen, Potassium and Phosphorus, as said for apricot trees.
Thank you
Sonny

Some of the oranges on my orange tree split open and drop to the ground.
Citrus fruit cracking is caused by an uneven or irregular watering, such as when you have a drought and then suddenly you get an abundance of rain. This moisture causes the skin to swell and eventually crack or split open. This article for cracking oranges should help: https://www.gardeningknowhow.com/edible/fruits/oranges/oranges-splitting.htm

I have had this semi-dwarf for 2 years. It has not produced any fruit. The tree has had blossoms but they fall off, and that's the end of any type of cycle this particular tree has had. Right now the leaves on the tree are a variety of colors, ranging from green to yellow. I bought a lemon at the same time as the orange and it produces like crazy. I water them both the same and feed them both the same. What's going on?
Perhaps, this article will be of some help: https://www.gardeningknowhow.com/edible/fruits/oranges/no-fruit-on-orange-trees.htm
Can an orange tree that froze and started growing again be fruitful? It is growing but there were no blooms or blossoms.
It is difficult to say for sure but the fact that it is growing and healthy is a good sign. While it may not produce this season (may have suffered bud damage from the freeze), it is highly possible that it will in later years. I would recommend keeping the tree indoors or a protected area outside to avoid it having to freeze again.
We purchased a foreclosed house last year. At the time of purchase in August (in Sacramento CA), the tree had 30 or so large beautiful oranges the were sweet, thin-skinned, and virtually seedless. The property had had no irrigation or maintenance for about 2 years. The tree is some type of grafted tree. The base of the trunk is about 10 inches diameter. I came in and lovingly cleaned up around the tree, faithfully fertilized every 4 weeks during spring and summer, used a soaker hose through spring and summer to water (trying to be careful not to get its feet too wet). The tree is planted at what is basically a huge berm so there is a lot of drainage. We got thousands of beautiful blossums and now have hundreds of small, almost tangerine sized fruit that have lots of seeds and are on the sour side. The rinds are still thin, but much tougher than before - the previous fruit rind was also thin but peeled so beautifully. The color on the fruit is also not nearly as pretty, kind of a yellow cast to the orange. What do you think has happened or is happening?

I am doing my final year project at the university and I want to ask something. I must put a soil humidity sensor on the trees, but I don't know how much humidity it wants and then how much water. The trees are orange, apple and lemon. I hope you understand because I am from Cyprus. Thank you. . . . .
