Hello Helpful Gardeners
I currently have two outdoor bonsai and two indoor bonsai. Last year, mid august (just before autumn), I also started some sprouts from different species meant to be kept indoors. Three of the sprouts where Chinese elm's. I keep them in my bedroom where the temperature is always at a minimum of 15c (59f).
The sprouts started out nicely and quickly had two/three sets of true leaves. Then when it got a bit colder and the daylight got scarce the color started changing from green to pinkish purple. It actually looked really nice . Two sprouts then dropped all of their leaves and are now just tiny little twigs. The other sprout only got purple at the leaf tips and is still holding on. It however has not grown for over six months. It is almost as if it is hibernating with it's leaves on. After a month of growing light treatment (the bulb that my serissa loves ) it still has not budged!
Today I did a mini scratch test on all three the sprouts, they all have a healthy green color underneath and are definitely not dead.
So my questions are:
1. Is it normal that inside elm's go into dormancy?? (never heard of it)
2. For the leafless sprouts: now that the weather is getting warmer and there is plenty of light, will they come out of dormancy naturally, or will I have to do something to activate them?
3. For the sprout with the purple leaf tips: how do I get it to ever grow it again, am I stuck with a nanosai sprout here?
Thanks for reading!
