Hi there.
I've got a Japanese Elm, around 3-4r years old, which I bought for my partner, but I seem to be the one left in charge these days!
I noticed this year that it was growing leaves and new branches at a crazy rate. Some of these leaves being really big, and the branches very long.

After some research it seems it wasn't getting enough light, so with the nice days coming, I've decided to put it outside from 8am until around 7pm or so.
Now, it's not been overly warm, a few windy days also, but after 3 days of being outside through the day, I noticed that some of the leaves, just a few, had lost colour and turned white.

The tree itself seems to being doing well outside. Branches are short and the leaves are small and in numbers, so I feel it's going in the right direction, but these leaves are a bit concerning, and after some googling, there are many opinions on white leaves, but I don't know which may be specific to mine, so here are some pictueres.

Thanks for any help!
P.S I know the tree probably still needs some work, but I am learning as I go!

First of all you have a chinese elm. (Ulmus parvifolia) not a japanese elm.

This is a temperate semi decidious species. Best grown outdoors year round. If you get deep frost for prolonged time, it will need some protection. But never bring it inside living room conditions which is lethal.

Now, for time beeing: if your area is safe from frost, just move it outside. If not, try to chill it down to 5 degrees until safe from frost. Onse moving it outside, start in full shade and move gradually into full sun during 4-6 weeks period. Once used to outdoors and full sun, just leave it there never bringing it indoors again. It will proboably be weak all summer, but if left outdoors as explained above it will bounce back next season.

I stand corrected! So a Chinese Elm.

It's been kept indoors for the life of me owning it, as I was told it can live inside as well as outside, but it has definitely looked better while outside.
As for frost, here in the UK, it's not too bad, especially now the weather is improving. I'll slowly move it from the shade to sun and see how that goes.

Thank you

Yes, I have seen so many care advices on chinese elms saying they can be grown indoors. Despite that, I have never seen any healthy tree grown indoors, but hundreds like yours. Very weak and tired after first winter indoors. I am in Sweden and my elm that has been protected in unheated greenhouse down to -15 is now starting the growth. Lots of small buds all over the tree waiting to explode in growth. Not one, ten or hundred but Thousands! All over the tree. With right care you will find yourself pruning handfulls of growth 2-4 times per grow season. I have never seen anything close to that on an indoor tree.

Thread steal. I live in Norway and we’re still getting frost/snow. The shop i bought the tree (also a chinese elm) from also avoided sending it until warmer weather, and have sold it as an indoor/tropical tree. I have recently purchased my tree and had planned to move it outside when the risk of frost is gone and then leave it there. I feel if i put it outside now its a death sentence. Or should it be outside? Temps between -5 to plus 5 atm. We also have very cold winters though (-15/20) for weeks or months. Will the tree be okay in an unheated greenhouse as surely it will still be freezing.

Hej lillebror .

No, do not move a tree that has not experienced the natural cool down in authum to freezing temperatures. You are right, that would risk killing the tree. If possible, put it cold but frost free until risk of frost is over. When moving outdoors, start in shaded position and make a slow transfer to full sun over a few weeks.

I have not pushed my elm to harder conditions than what is mentioned above. So I cannot tell you the limit. But your conditions sounds to be close to it. Is it possible to setup a heated area within the greenhouse? I have a 4 square meter grow tent at 5c in my greenhouse for my non-hardy plants. Well isolated its not a big cost to heat and I think your best option.
