Snow on a bonsai is one of the prettiest sights to behold.
With 2 c-clamps, plywood, and a couple of 2x4 gussets, you can keep it OUTSIDE the same window, enjoy it every day. Water easily. And it will thrive.
$20
Or you can set up an outdoor video camera and watch it on your tv. Record it all and make the dopest progression video ever.
$200 minus video sales in 20 years.
All my trees are on windowsills. There is no reason at all you can not have your enjoyment, and a healthy tree.
There is more than one way to skin a cat. But the cat will still die right?
Why skin it? I know, its a cat. Meow. Slice.
Let your tree live! It is way better than a cat. Unless the cat is a tiger. But then it would enjoy an indoor ficus! Unless it is a siberian tiger, back to Tamarack.
Either way, you are much more likely to own a tiger than have a happy juniper inside. We can talk about feeding it rice cakes and butternut squash all day. It still wont become a Puma. Which, may frequent your yard. Or a lynx. But there are too many links to threads with questions like this that all get answered no.
But your tree will be safe from it up on that rig you made on the windowsill!
