I just found out I won’t be able to use my normal winter spot this year. It was a friend’s barn and basically perfect for winter Bonsai storage. I’ve also just been given a few potentially problematic trees on top of this, so I have some questions (I did read the Winter Care under 20 thread).
First - I was recently given a Privet (likely Chinese Privet) and two Chinese Elms. Seems like these three trees have been raised as “tropical” and never seen a real winter (they are from my very well meaning spouse so there’s extra pressure not to kill them lol). I don’t have an awesome place indoors as all my windows are tiny. Wondering if anyone’s had luck supplementing with strong grow lights for situations like this?
Second, regarding the rest of my trees. It’s a mixed herd of deciduous and conifers (and some deciduous conifers lol) - lots of young maples (mostly Trident with two Katsura and two Coral Bark), some Dawn Redwoods, and some Itoigawa Junipers - I don’t have a great place to winter them on my property but am thinking of getting a greenhouse. I know temp can be a concern on days when the weather gets a little warmer so my thinking was to get a wifi thermometer, leave the door open, and possibly leave some of the panels out to keep cool air circulating. Does this seem like a reasonable approach? If they’re in the greenhouse, would I still need to cover with mulch? What would you recommend? I’ve been kind of spoiled with that barn so it’s something I haven’t had to deal with. Thanks in advance for your time!
