Growing Palm Trees in Zone 3-4
Comments (11)Great thread, I love out-of-zone plantings! Can a windmill palm really be grown in zone 3 or 4, even with generous winter protection? That would be great, but is seems way out of zone here in the Cdn prairies. I checked out the website, and I've seen them growing on the west coast of Canada (pic included below), but that's a very mild climate, like zone 8 or thereabouts. Catalpa seem reasonably hardy for prairie gardeners looking to test the limits. I've got a small one (two feet high and several years old) growing in my increasingly shady back garden here in Edmonton. It's still very small and is sheltered from winter winds by a nearby fence, but it doesn't seem to have suffered much winterkill during the past couple of winters (but they weren't harsh winters). Ginkos are great... I had a small one but it didn't make it past it's first year in Edmonton's suburbs, yet I know of one on the University grounds downtown that has survived at least 10 years. Actually, I haven't seen that tree in about 10 years, so I really need to locate it again and see if it is still doing okay. I used to also watch a ginko growing in Drumheller, Alberta, near the Red Deer River (pic included below) -- last I saw it was small but healthy, but I haven't checked it out for the past decade so I really need to take another look. My sugar maple is about 12 feet high, growing more as a bush than a tree. It is maybe 10-12 years old, and has a fairly thick trunk. It can winterkill quite severely, but has been doing pretty well the past 5 years or more. I have a butternut tree roughly 12-15 feet tall, at least 10 years old, and it has produced nuts for the past several years. My grapes (Valiant) produced heavily this fall, and the wine from them is now bottled. Pears (Ure) are usually ignored when they ripen, but they are tasty and the tree has been growing vigorously for 15 years. Magnolia and Northern lights azalea survived several winters but seemed to get increasingly smaller each year, eventually discarded. Forsythia did great in a mild winter, but crappy otherwise, and were a pain to chop out, including all the sucker-plants. Well, that's all my info on out-of-zone plants. If I can actually grow palms here in zone 3, please let me know!

Comments (7)>>I wonder If I graft the japanese maple onto a regular hardy maple in my climate?Grafting I'll use the example of roses here. Just like japanese maples, most roses are not hardy to zones 4 and lower. The are zone 5 and up. Hybrid tea for instance are not hardy but they are grafted onto hardy roots. Unfortuntely, this doesn't make them hardy in zone 4 and down, we have to protect them heavily so they will come back the year after and even then you run the risk of loosing them. Not because the root system is in danger but because the grafted part is. But even if you loose the grafted part during the winter, you still may have roses that will emerge from the root stock, below the grafting point. Of course, they wont be the same hybrid tea that you bought since that part died, but a hardy rose from the plant on which it was grafted. I would say the same rules would apply to japanese maples grafted onto hardy maple roots. You probably know the Explorer Serie roses. These roses are hybrids but are not grafted, they use their own roots to grow from and they are hardy to zone 3 and some to zone 2. I have 5 of them doing very well and they never needed any kind of winter protection and I never even thought about giving them any either (zone 4b QC, Canada). Why is this? The crosses were made between hardy species and/or cultivar from the the start and the breeding was done not to impart hardiness in the first place but to develop other caracteristics such as colors, trailing habits, short plants, diseases resistantce, etc. They probably used less hardy roses in their breeding program to bring in some new genes unvailable otherwise. Hybridizing If you cross two zone 5 plants like two acer palmatum, you'll end up with a bunch of other zone 5 plants. But if you cross a zone 2 plant with a zone 4 plant, you will probably end up with 80% of the plants hardy to zone 3, 10% hardy to zone 4 and 10% hardy to zone 2. Then if you take one of these new zone 3 hardy plant, roses for example and cross it back with a zone 2 rose, you may end up with a 50% zone 3 and 50% zone 2 stock. And if you cross back again one of these new zone 3 rose with a zone 2 rose, you may end up with a 75% zone 2 - 25% zone 3 ratio. These same rules would also apply to maples making crosses between 2 different species, one of them being the japanese maple for the first cross. The difference is here: in the example of roses I took, the desirable plant and the one used in every cross was a zone 2 and the goal was to bring a zone 4 plant to zone 2. With every cross I did I added some zone 2 hardiness to the gene pool. With the japanese maple, we would be working against the odds, the desirable plant and the one that should be used in every cross is a zone 5 plant and that would bring a zone 3 plant to a zone 5 only. And if I added more and more zone 3 maple, I would be loosing more and more of the japanese gene pool. Either way leads you away from the wanted result. And we haven't even said a word about what could be recessive of dominant in these crosses, which is also a very important factor to keep in mind. This can be observed in the new clematis hybrids that are reaching the market these years. Old clematis were hardy in zone 4, but crossing them to warmer growing one has yielded many new very desirable hybrids, but only hardy in zone 5, 6 or even 7. We have gained in beauty but lost in hardiness. In a word I don't think grafting would be successfull in the way you would want it to be. And breeding wouldn't work quite the way you would want either from what I understand from what you said. These are two of the reasons why I said that selection was a much better approach in your case. It is not an easier or shorter one way to do, only a safer one. Hope this helps!...See MoreA group to discuss fruit trees to graft in zones 2 & 3
Comments (26)Hi Greg :D Thank you so much. I havent heard of that kind of Apple yet but am very interested. I would really like to plant some to use as rootstocks down the road. I am really excited about grafting, so far I grafted 12 Apricot trees, fingers crossed I get at least 1 make it hehe I will be grafting some Pear and Apple trees next weekend providing my rootstocks I ordered arrive by then. I met a very generous friend that mailed me scion for 2 kinds of Pear and 2 kinds of Apple, him doing this kind act gave me a chance for more experience grafting... I am so super grateful :D...See MorePink Flowering Tree Zone3b
Comments (2)Yes, you have IDed it correctly. Crab apples vary quite a bit in size, flower color, and fruit depending on cultivar. Malus also includes apples as well as crabs....See Morenatrldsastr
