Post subject:  Yellow leaves on Chinese Elm

Last year I discovered bonsai and eventually picked up this tree around this time last year. It was discounted and not doing well so I fixed it up, some of you may have read the post I created about it. The tree was originally an indoor tree, so over the first months I acclimatised it and placed it outside.
During the winter it was placed inside my plastic greenhouse. It survived and leafed out well for spring, interestingly the leaves came through a lighter shade of green from before. I re-potted it in earlyish spring into a more appropriate pot with better free draining medium. The tree is placed in full sun and I water it well when it needs it, I've recently got a water-but so its lovely rain water. I have been feeding it weekly at half strength using bonsai focus.
The tree has the odd couple of yellow leaves not in any particular area from what I can see, they drop of freely.

I do have another Chinese Elm that is sat next to it, but hasn't got this issue. The leaves are darker so maybe its a different variety, although it was also sold as an indoor and has been outside since spring. That tree has also taken to feeding differently - shooting out long sappy shoots at times. I'm quite pleased with the progress of this other tree and I'm quite looking forward to showing you all its progress.
Check out the photographs below. I'm happy to answer any question if more information is required.

Its nothing to worry about, Chinese elm often drop old leaves in summer, some of mine are doing the same. sometimes the yellowing leaves that drop freely can also be a sign of over watering.

ah fair enough, over watering you say? I'll experiment with slightly reducing the water. It does seem to seem a little odd though as it appears to be losing more leaves than its pushing out, especially compared to its neighbour. I guess all trees have their own different personalities you discover over time.

I've noticed a couple with mine, with the terrible weather this year we've been getting in Glasgow I'm going to keep it inside until next year. I've noticed a few yellow leaves though not many and seems to be acclimatizing well as is throwing out some nice new growth (needs a trim actually!). I'll keep a tight rein on watering though hasn't been too many to cause concern

I'm not subscribing to the over-watering theory. It occurs quite naturally to many species around now. Leaves are shut off to make room for new ones. I have noticed it additionally on my Nothofagus antarctica over the last two weeks. Worry ye not.

Your going to keep it in side until next year? All of mine stay out doors over winter they loose leaves and regrow like ever other tree I have if its really cold it's under the bench ect :smallthumb:

Hi I don't think you have anything to worry about but the one thing I would do is check your soil a lot of these trees come into this country in a heavy clay soil and some dealers clear the surface of the soil then put a top dressing on to sell the tree so if you find the tree is in clay wait for Spring and change all the soil by gently washing the roots in a bucket of water and repot with a soil that has good drainage.

I know Will, I'll move it out next year once I have somewhere for it in my garden. Just moved into a new house so need to sort out a spot out of the ferocious winds (worst summer ever).

:mad:
