For the first two years, my tree gave plenty of sweet, juicy fruits. Now (the past year and 1/2), there is no fruit and there is this odd 'tufty' growth everywhere where there are supposed to be new leaves and blossoms. One nursery said gall. The Pima County co-op extension said it is underwatered. Hope you can solve the mystery.
oops, hit the wrong button... There are more articles about sooty mold and other problems with citrus. You can access them by using the search window at the top of the page.
I doubt that this would be caused by underwatering. Usually, wilting then leaf drop is the first sign of underwatering. I am not framiliar with gall on citrus, however gall usually appears on woody branches and trunks. Gall is usually not widespread over an entire plant.
The description of "fluffy" isn't quite enough to make a decent guess as to the real problem. If it is gray or black and looks like mold, it's probably sooty mold. this article will help: https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm
My calamondin tree started to lose its leaves. I first thought that it was the caterpillar but I already got rid of that culprit, but still it won't produce new leaves. What could be the problem and is there a remedy?
The most likely problem is water; after that, check light and fertilizer. These articles have more information: https://www.gardeningknowhow.com/edible/fruits/citrus/leaves-falling-off-citrus-tree.htm
I have a Calamondin tree which I bought for Chinese New Year. When I brought it home, it started to drop fruits and lose leaves so I decided to put it outside. I should tell you that I live in KL and the AC is on in our apartment most of the day. The outside temperature is hot and humid. Since transferring the plant outside, it seems to have died, even though I have watered it regularly and it is not in direct sunlight all day. Can I save this plant?
A couple different things may possibly be happening here. This plant is recommended for plant hardiness zones: 4-11. Malaysia is zone 14. So, a calamondin tree is not very ideal for your area which may explain why it has not been doing well since placed outside.
I am wondering if maybe the tree has been overwatered - citrus will falter in waterlogged soil. Is your soil damp/soggy or dry to the touch? Water only when the surface inch of soil has become dry.
I would also inspect your tree for mite and scale infestations, as they can affect the health of a citrus tree.
Also, have you fertilized your tree at all? If not, I would recommend that you do so.

We have 3 Citrofortunella mitis (Citrus Mitis). 2 weeks after changing the pots (with holes and gravels in their bottom), I gave them liquid fertilizer containing iron. After that time, some of the green leaves have fallen and then little by little the leaves become brown and wrinkle and then fall. Now the trunks have become brown and dry. Also, the soil is always wet, even if I do not water them for 2 weeks. How can I rescue them?
The constant wet soil is a concern.
The growing medium is to heavy and needs to allow drainage.
The tree soil should dry slightly in between waterings.
Here is an excellent article with specifics on how to grow and feed the potted citrus.
Planting area needed between calamondin orange trees?
Dwarf tree recommendation is 6 to 10 feet.
Calamondin are an ornamental variety and could be planted closer.
I have a 4 year old Calamondin tree that is my pride and joy. This summer was the most productive summer yet and the tree was filled with citrus until a very stupid mistake I recently made. My tree is planted in a very large pot so I can move it inside during the colder months. Because we've been experiencing such warm weather this year, I've just left the tree outside until one extremely cold night when temperatures reached 10 F. I realized my mistake the next morning and immediately brought the plant inside and then began to notice a very pungent smell coming from the tree. All of the citrus that was once very firm is now mushy and wrinkled and several leaves are starting to fall. I'm assuming everything froze and is now rotting. What do I need to do to make sure my tree survives? Do I trim off all of the fruit and start again from scratch?
Yes, remove the fruit and discard it.
Trim away any dead material and you will need to wait and see.
Give the tree a full sun location and maintain watering but be careful not to over water.
Do not fertilize while it is recovering.
I have one of these trees and have had it for about 3 years. It is not dying...but not growing. I have it planted in a 3-gallon plastic pot with a drain hole. I water it once a week and use a Earth based fertilizer. Any suggestions?
Your Calamondin should be planted in a large pot with a mixture of 1 part each potting soil, organic compost, and vermiculite.
Give the tree plenty of room for it's roots to spread out and establish a healthy root system.
The tree should be repotted every couple of years to prevent it from becoming root bound.
This may be the case with your tree showing no new growth.
