sick fukein tea?

[crash712us]

after noticing I have some insect larvae in my soil a little of a month ago I decided to repot. prior to the repot the tree was doing well dispite the larvae I was told they were silver worms and would not hurt the tree. But the tree dropped all its leafs since repotting and has been bare for nearly a month. I am starting to get worried. any advise would be much appreciated.

This tree is known for attracting parasites and aphids. They're also quite tricky to keep and not really a beginners tree. I've lost two of them in the past and have had a real struggle keeping the one I've got now healthy. I can share what I know about them so far:
First of all you need to look very carefully for aphids or parasites. You can see then flying sometimes around the tree or even as specs on the leaves. They suck sap and weaken the tree. Some leave honey, ticky discharges on the leaves.
If you have aphids or pests, use a soapy insect killer but dilute the dosage as fukiens are sensitive to chemicals. Spray the foliage below and above till you notice the parasites are on the retreat. Make sure the tree gets ample light and put it outside on sunny days for a the odd hour or two.
I believe the trouble I had with my own current tree is it was too stuffy indoors and also temperature drops due to the very cold weather in Winter. Aphids began to bombard the tree and the leaves lost vigour and a few dropped. Today is sunny so I put it outside, continue to use soapy insect killer as well as light feedings of bonsai food. It does seem to be doing far better and I think it will be O.K.
In your case, I would remove all pests by hand and by spray, put the tree under a light, keep the temp around 65 degrees farenheight and hope new leaves will grow. If they don't soon it's too late.
I find mine hard to keep but think when healthy they are a very impressive tree and nopt one you would ever find in a garden over here.
