Hi! I've done a few methods before here in SW PA, zone 6. I did garage, they survived. I sunk them in holes in the ground, I later realized it was a low spot and and they were pretty much completely submerged in water with no wonder protection. They all survived til the point I removed them from that are, a couple later died (and Idk if it those that died were because of that method, or because i planted them out in a bad location soon after). This year, I have too many to fit in the garage, so I'm thinking of wrapping the containers with old carpeting I pulkd up, and dropping them in tires and filling the cavities with old linen or something between them. I hope that will be enough. Thy shoild have more protection from wind and sun here than last years method. Every year I do something different (and seeming a little more risky) and every year I live w anxiety not knowing if I did a bad thing, and fear one of my favorites will be the casualty and my dreadful learning experience
I just bought 11 JM in 1 gallon pots. It's October 28th and I will put them in the ground tomorrow. Will the first freeze kill them if I don't cover them since they won't be established by then?
Great question. I don't know anything about your location so can only answer in generalities on this. When the tree has time to get roots growing into the surrounding soil, this affects not only its ability to not get blown over, but also its ability to access water and nutrients. And, as a result, it also affects the tree's ability to get through cold and warm times. Short answer for you, no, the trees won't necessarily be killed(especially if you mulch well). However, planting just before winter is not the best time of year to do so. In a coastal climate like Oregon or BC, planting in the fall is a lot more practical than in cold winter locations. The warm coastal locations still permit a lot of root activity in the soil through much of the winter. In places like Chicago or Toronto, planting in late October would be on the bottom of the list of when to plant, for me. Although, some people put potted plants in the ground to overwinter, so that conflicts with my theory a bit. Mulch with 3" of wood mulch. A tree in the ground is better off than one in a pot over winter.
How often should you step up pots? Or if you decide not to, should you do a root prune and throw some fresh soil in the pot? How often should you do that?
There's no quick answer for this as some trees are more vigorous in growth rate. Then there's weather, moisture and food availability variables. Speaking in generalities, my 1 gallon containers will almost always get upped to a 2 before the growing season is up. With the smallest pot sizes they are very sensitive to heat, moisture, etc. So, the growing environment may be in fact "faster" than a larger pot. With larger pots, it varies. I would say that many of the containers larger than 2 gallon get potted up once a year. I grab the lowest part of the trunk, lift the pot and tree off the ground, and gently tap on the pot rim using the palm of my other hand, to get a peek at the rootball. Harder to do with pots that aren't plastic or depending on the pot shape. Roots circling=time to root prune or time to up pot. Roots visible but just reaching the edge of the rootball=okay to leave in the same pot. And, the growing media in the pot should be refreshed every couple of years or so. This doesn't mean shaking the media off the existing rootball! If you're potting up, a little new media in the bottom of the new pot and of course after you put the tree into a new, bigger pot it will have room on the sides to add more media. Feel free to email me through the website if you want further details or more clarification.
Hello. I live in Ireland and I think it is zone 9 or something. We tending to get to - 2 to - 3degrees celcius§some nights. We get the odd bit of snow but it is quite cold. On average we hang around 1 to 2 degrees most nights. Would I need to protect the J.Ms in my zone? Would a bit of much and a bubble wrap layer suffice? Thanks for any advice.
Hi. If your winter temperatures don't get too much below those you mentioned, I would not be concerned with any protection other than keeping trees out of hard winter winds. Trees in the ground are even more hardy. Trees in containers/pots can be damaged below -10C.
@SimplyJapaneseMaples thank you. I'll keep that information in mind. We are a few 100 feet up from sea level so winds can get a bit strong and when it gets cold could be damaging. I can at least shelter the pots a bit against my house and sure just hope for the best. New to growing J.Ms and this will be my first winter with them 🤞
@@richiep3520 You will have different growing zone rating system, just as Canada's is different the USA's. However, I appreciate that Ireland is moderated by ocean temperatures so it ain't Siberia! Yes, could be a big difference between being blasted by winter wind and not, despite being just down the road. Mr. Maple, and my channel are two good resources for maple growing info.
Hello! I'm in Calgary and I've got a couple of acer palmatums I transplanted in clay pots. They're the bonsai type. What are some of the best ways to keep them alive here in my zone (3 or 4 I think) come fall/winter?
Hey, I have several customers in AB and Sk. Most of them bring their trees into unheated garages or shed spaces. The main thing is, out of the winter wind and slightly warmer than direct exposure to outside temperatures. In pots, -10C is getting into the danger zone, without additional protection. Bonsai pots being shallow, perhaps less. You can also mulch the entire pot/container with any number of items. Bury the pot in the ground and then mulch. Sun is not important but the trees still need occasional watering. Be careful with something like a shed that has windows though, you don't want any drastic swings in temperature throughout the day.

I think you need a Japanese maple specific garage. Cars not allowed.

The trees need to go into dormancy. Anything in the single digit temperatures and below works. So, inside the warm house, not an option.
@@SimplyJapaneseMaples I'll definitely keep that in mind. Thank you so much for tips!
What zone are you in
Hi John. Zone 6b/7a (Canada). This equates roughly to 6a in the US.
