Answer 1

Citrus are shallow rooted trees so one possibility is they are planted to deeply and can no longer get oxygen. The first set of roots should be at, or near, the soil surface. If you must dig down around the trunk more than one or two inches to find the first set of roots, the tree has been planted too deeply, or soil has washed in around the trunk. In any event, this soil should be removed.

Another thing to do is examine the leaves that fall, are they discolored, shriveled, new growth, mature growth or fresh looking. Examine the leaves for the petiole. Did the petiole (leaf stem) remain attached to the leaf blade, or did the petiole remain with the branch? When a citrus leaf falls from the tree because of normal reasons, the entire leaf blade and the petiole abscise from the branch and fall. Many times when leaf drop occurs due to stress only the leaf blade falls and the petiole remains attached to the tree.
Tree stressors.
Lack of water, nitrogen, insects and frost injury may cause leaves to drop. Have you had a sudden temperature & humidity shift? Wide temperature changes can cause leaves to drop. If it is in a container did you bring it indoors near a heat vent, that could dry the leaves causing them to drop? If you take a magnifying lens to the tree can you see any minute insects? Scale is the most common cause of leaf drop. Have you fed the plant while it was stressed? Plants, once stressed, should not be fed.
Does the tree have good drainage and air circulation?

Answer 2

I only know of two things that would cause the leaves to shed as fast as your trees leaves have done. The first, and most likely, is that the trees have gotten very dry. Dig down with your hand to the original root ball (the soil the trees were planted in when you bought them). The odds are that this root ball, containing all of the tree roots, has dried out before the tree has had a chance to grow new roots outside of the root ball. This can be aggravated if the tree was planted too deep. The original root ball should be even with the surface of the soil, not below the surface. The soil around the root ball may have been well watered, and be wet, and the original root ball will be dry.
The second possibility, and less likely because of the drought most of us have been in this year, is that the trees have stayed very wet. If the soil has stayed too wet for a long period of time the roots would rot, or a fungal pathogen could have invaded the roots causing root death. It is also possible that the trees had a disease (most likely one is Phytophthora) when you bought the trees. Phytophthora on citrus causes the leaves to yellow, and the midvein of the leaves will be bright yellow. This is very distinctive, it is not a subtle yellow color.
I take it back, there is one more thing which could cause this. If lightning strikes a tree, or strikes very close to a tree, this could happen.

Answer 3

did somebody pour hot water on the plant?

Answer 4

I THINK IT IS JUST STRESS, THIS IS HOW TREES DEAL WITH IT AND CONCENTRATE ON ROOT GROWTH. YOU SHOULD SEE GROWTH ON THEM IN A COUPLE MONTHS.
