people are going to want to know where you're located, or at least an idea of how cold it gets.

I've successfully stored a maple in a metal garden shed, no windows, and brought it out as the snow melted. I didn't water it or anything while it was dormant. There might be better methods but generally you want it cold enough to keep it dormant throughout its resting season. Some put trees against their house, others in an unheated mud-room. Keep it sheltered from the wind and you should be fine.

Kind of a dumb question but thought it's relevant: Is a greenhouse during the winter suitable?

(I like your username, BTW.)

Your location is relevant, as Jess alluded, because it gives us a general idea of what your climate is like.

Japanese maples are pretty winter-hardy. Depending on where you are, you may be able to just put them under a cold frame or tuck them into a sheltered area of your garden. They can handle several months with their rootballs frozen.

Protection from wind will be important, since wind both accentuates cold (wind chill) and also desiccates. The fine twigs of your maples won't do well with frequent winter wind.

Evmibo, yes, an unheated greenhouse would be just find for wind protection and for moderating temperature spikes. Unheated: Acer palmatum needs winter dormancy for long-term health.

I live in Chicago, where it get bitterly cold in the winter. I've been using a freezerless refregirator for my decidious trees. My pines go outside in a cold frame.

question back at you, what kind and size pots.

Water as needed, not really different than summer, except for frequency. Dormant or not a dry tree in the winter dies.

They should be water sparingly during winter. Make sure the soil is kept moist and not allowed to completely dry out but make sure the soil is NOT saturated. What type of shelter do you plan on placing them in over the winter, it might help us give you pointers? I found the unheated garage to work best but that might not be applicable for you due to number of plants.

A frozen pot doesn't need to be watered. For many years, I overwintered the majority of my collection, including tridents and palmatums, in my unnattached garage in usda zone 6 MA. Thanksgiving weekend, they would be placed on the concrete floor, mulched over the pot, and watered in. The mulch would freeze solid by New Years and stay that way until March. Except for the occassional application of snow to the mulch, I wouldn't need to water until late March, or even April. I never worried about watering over the winter...but you DO have to worry about the mice. They'll de-bark a medium sized maple overnite. Traps and mothballs in cheescloth bags seemed to do the trick.

Dave is right, if temperate for your area, the best thing is keep it frozen, but keep it where you can get to it for early spring/late winter work and workshops.

The evergreens go in a cold storage outside eavily mulched. They stay outside all winter long and I don't water until the spring. They get plenty of moisture from the mulch of leaves. The maples and other trees go into a refrigerator in my basement for dormency. I give them a little water once a week.
