What type of soil is this tree planted in and where do you live ? The Fukien tea is tropical and needs humidity and lots of water when outside if it is planted in a good draining Bonsai soil. When my trees are outside I keep them in the shade and check the soil before I put them outside and when I bring them back inside, and water if needed. Just warm air will dry out these trees roots so you got to be careful. when watering remember to soak the pot under water till bubbles stop coming up then you know that it is good and watered. Mist the leaves when indoors or at night,but never in direct sunlight. I hope this helps and I hope your tree is getting better. good luck:)

well.... haha just regular potting soil with some grit added, i haven't got around to buying any good bonsai soils, i was going to go to a nursery and buy some sphagnum moss and just plant it in that until it revived. but i was hesitant because i just repotted it, i didnt want to repot it again. now all the leaves are gone, but the bark is still green, i am thinking of potting it in a bigger pot because it's in a very small cascade style pot and i can never get my finger in the soil to see how moist it is, and i cant really tell by sticking a toothpick in the dirt either, the dirt in the bottom of the pot is still damp but none of the roots go down that far. so i don't know if i should water it or just leave it alone... its inside right now, and i dont want to stress it out by moving it around until it starts growing again, but it gets almost no light in the room its in now, but i have a nice shady back porch that gets good sunlight but never direct sunlight, and its really humid here. so should i put it outside? and re-pot it. and what kind of soil should i use that i dont have to order from a website. something that i can pick up at a loes or a local nursery is preferable. i've been wanting to try sphagnum moss for a while, should i plant it in that, or should i use something inorganic?

Did you managed to figure out and solve the problem? I'm having exactly the same problem with exactly the same kind of tree :( It looks so sad and sick :( And the leaves are all falling off and turning brown.

No pics of the whole tree?

First they only need a few hours of direct sun a day. If you put it outside all day you will lose a few leaves but nothing major, the bigest problem is probably watering, it just needs more than you're giving it. It is also probably in a small pot, you can try moving it into a larger one with additional soil mix, more soil-more water, limited stress.

You have winter and summer, I don't but, I have a very large FT bonsai. It's planted in a mix of coarse sand and Basalt chips (nothing else here like bonsai soil) and kept, like the rest of my trees, under a canopy which gives them about 80% shade all year round. Even with that I MUST water twice a day or they start to wilt.

One easy fix for you would be to get a large container of screened Pine bark mulch and dig the pot into that (about 2-3 times the size of the pot) give it some drain holes. That may solve some of the moisture loss problems.

Sounds like a bad word........Wow

Also Google it, there are many fine places you can get a lot of symtom/care info. Jerry Milsiak has a very good batch of tropical and semi-trop information.
