I had the hardest time making a seedling Crepe Myrtles this spring. One died because I touched it like a noob then it bended an died -_-. The other one had not enough sun so it dried out and died, another one died because I tried inside and I think it was too cold...

Then I finally manage to save one from death by putting it outside under the morning sun and inside a small greenhouse to keep humidity. It had now like 4 pair of leaves and it's still pretty small. I don't know what to do with it during winter since I don't have a lot of sun in my apartment and it's pretty cold (20-21 Celsius)

I live in Quebec City, Canada where winter are long and very cold. So, I don't think I could let it outside, but at the same time, I can't really bring it inside since it won't be in a dormant state...

Would it be safe if I buy an hydroponic lamp with a timer during winter? I read that it's not an Indoor Plant... Do you have any other suggestion ?

There is definitely a solution here. You have to bring your bonsai inside for winter unless you have a heated, very consistently heated greenhouse. The way to do this is to HARDEN your plant (backwards I guess) to get used to the less humid, less light, drafty home environment. Bring your plant inside for half an hour everyday for 3 or 4 days, increase the amount of time to and hour, then 2 hours then 4 hours. Give it a place of its own with lots of light but not direct light. Definitely near a window. If you see any stress in your bonsai cut the time inside by half. Bonsai needs to be watered every day (discuss this with a Bonsai master depends on the size of your plant and its pot) and I found tap water to be a death wish. Get distilled or bottled water. Or use a friend's well water. No saucer beneath, easy easy on fertilizer during the winter months. Then in spring, harden your bonsai the other direction. A great spot is a covered porch. The daylight will be short, the reduction in fertilizer will put your tree in a semi dormancy as if it were in a Japanese winter. Put it in a sunny, cool room, like a guest room. No pruning, no cold or warm drafts.

If I were you I'd get advice from Bonsai masters! Bonsai is the ultimate training tool for gardeners!

  • Even if the winter is like 8 month here? Will it last that long? I read on the notice that his winter are suppose to last 3 months... That's cute but here in Montréal, Canada, 3 months is the summer haha

  • That plant will go into a semi dormancy just because of the light dark cycles. You can acclimate this bonsai to the home environment and in the spring begin to harden off your bonsai back into the out of doors. BABY this plant. Everything is slow, methodical and take no chances. I would find a cooler room, lots of light or a heated greenhouse and make that your bonsai's home. I know your climate. My indoor plants go outside under a porch roof for as long as safe then come back inside...for winter. They are able to make lots of food for themselves to last the winter.

  • I'm a little lost here,you said " I would find a cooler room, lots of light or a heated greenhouse"? But I though during dormancy, it didn't need any light...

  • majordifferences.com/2013/12/… this article. Light is important as well as dark...dormancy is a bit different on a different scale. If the leaves completely fall off then no light is necessary. Plants in pots, allowed to be outside, their roots are vulnerable to the cold. The most vulnerable part of a plant are the roots. Thus the babying. Your plant is not normal. Dormancy might happen but because you are controlling the environment it just might stay in a semi dormancy and needs a bit of light.

  • Thanks a lot for your advice. I might have few other question lol... I made the stupid mistake of planting the seed in a small bonzai pot...I realized later that you start training your bonzai after 2-3 years ... Should I transplant it in a bigger pot before summer end? Also, when should I start bringing it inside to prepare it for winter? I want it to be as strong as he could get before winter
