If there's still FRESH-looking green (not pale chartreuse-ish
yellow green) under the bark, there's hope.

But STOP SPRAYING, and ease off on the watering -- a lot. Ill
trees don't use much water and too much water will make the roots
situation worse.

You had/have a root rot. The reason you saw so few was they'd
all rotted away into the soil. Chances are you've been watering
too much from the beginning.

Water this tree ONLY when the soil feels dry under the surface.
Dig in with a finger to check, or keep a stick jammed into the
soil and feel the dirty end once a day and water when it gets
dry.

Put the tree in part shade (OUTDOORS, assuming your temps are not
well below freezing).

Good luck.

Cheers,
I've been trying to keep it damp - will check on the shade of
green - it was quite bright last I checked.

I'm in Scotland, temp for the next few days is 10-15C (40-50F ?) will
it cope with that far a bit?

Thanks again,

Dunk,
What is the size of your Sageretia? Is it a collected specimen with dead
wood on it or signs of large old cuts?
Is it losing branches from the bottom of the tree up?

Hi Jerry,
Yes the branches it lost were at the bottom of the tree, it's about 8"
tall
shoudl be around 12 years old now. There are a couple of large old cuts,
5mm branches
cut off lower down.

Thanks,
Dunk

Dunk:

Water reduction alone WILL NOT solve the problem IF the tree has root rot.
This is a fungus, and it will need to be treated:

1. Remove the tree from its pot and inspect the roots. If the roots are
black, cut them back until you see whitish cores.
2. Remove the old soil and soak the root pad for 15 minutes in a fungicidal
bath. Benomyl, Funginex, or the equivalent product will do.
3. Repot the specimen in a fast-draining soil with a modest organic
component. The objective here is to promote root growth rapidly and to minimize water
content in the soil.
4. Place the specimen in indirect sunlight. When you water, water it with a
solution of Roots 2. You should be able to get this sent to you from the UK.
It unequivocally works.
5. As Jim recommended, place a chopstick into the pot and remove it on a
daily basis to check water content. When the chopstick is almost dry to the
touch, thoroughly rewater the specimen.

The temperature is a bit cold given its health. I recommend moving it
indoors at night and back out when the temperature is at least 50 F.

Cordially,

Michael Persiano

OK, see, that's not how *I* make decisions on when to use a systemic fungicide. First I consult "Fungi on plants and plant products in the United States" by Farr, Bills, Chamuris and Rossman, one of the most useful books ever published (if you're a plant
pathologist). Under Sageretia, only 3 fungi are listed, none of them pathogens. This isn't surprising, since Sageretia is such an uncommon plant of little economic importance: not many people would be *looking* for diseases. So I did a Google search,
and found an APHIS document on the risks involved in importing Sagaretia from China: "Importation of Chinese Penjing into the United States With Particular Reference to Sageretia thea, 2003."

Look how this document describes bonsai:

"The art of artificially dwarfing plants is a time-consuming and highly labor-intensive activity. The resulting plants range from approximately four inches to 60 inches in height, and the value may range from $10 to $10,000 per plant. The median price of
an artificially dwarfed plant is close to $100 and varies with the age of the plant regardless of size. Plants imported from Asia (Japan, the People’s Republic of China and the Republic of Korea) represent approximately 80 percent of the value of the en
tire artificially dwarfed plant market in the United States ...The volume of artificially dwarfed and other dwarf plants imported into the United States increased in recent years from fewer than 600 plants in 1993 to over 54,000 plants in 1998."

The document then goes on to list all the fungi ever recorded on Sagaretia world-wide. Of these, most are foliar pathogens. A few are listed as occurring on stems: Ascochyta, Diatrypella, Phoma, Phomopsis, Leptosphaeria. Of these, it isn't clear which,
if any, are already present in the US. The only one that would alarm me if I isolated it would be the Ascochyta; the others are probably stress-pathogens that wouldn't attack a healthy tree (although without specific epithets one can't be sure). None of
these pathogens attack "wood", so symptoms would be readily visible on dead twigs and identification could be easily done by Cooperative Extension. And what would they recommend? They would recommend cutting off the dead areas.

So I would not spray the plant with a systemic fungicide.

Nina, taking 20 minutes to state the obvious, but now knowing a lot more about the pests of Sageretia.
