Advice on some new Japanese Maples needed

Post by Schattenfreude »

Hey folks,

Last fall a large nursery held an auction to get rid of most of their trees/perennials. I was lucky enough to get some new Japanese maples at ridiculously low prices. Originally I'd planned to keep them all in containers, but I'd like your advice as some of them can get quite tall, I've read. All of them came in 3, 5 or 7 gallon containers. Could any of them tolerate 90+ degrees in full sun between 1-4 pm during July & August? Are certain container shapes/material better than others? I'll have to bury the container in the ground during the winter....
  • Koto no ito (4' tall)
    Katsura (5' tall)
    Okushimo (5' tall)
    Kamagata (3' tall)
    Eagle's Claw (3' tall)
    Autumn Full Moon (5' tall)
    Sango kaku (4' tall)
Thanks for your advice.

Kevin in KC

Hi Kevin,
I doubt that they will stand your 90+ full sun, I would plant them in large pots consisting of 60% eracacious compost and 40% grit or pea gravel keep the compost moist BUT not wet and as they are in large pots you can move them around your garden to suit the weather conditions.you can visit my website and see my Japanese maples which I have kept in large pots for years with no problems at all, but we don't get the sun temperatures that you get.

George do you know how cold they can handle to stay in pots during the winther?

Do it depend on where in japan they come from ? The country have several clima zones.

I'm told they can not surwive in pots here... they even are problematic in the garden ect.
:hmm: then the nurseries say the same about cedrus and they are so easy.

My zone is 7. Brittish people do not use zones, right ? Up to minus 17 C :wink:

Hi,
I really couldn't say how they would survive in your cold climate but I do know that in really cold winters here if they are in small pots they need there roots protecting but in the large pots that I use they are quite allright.

George,

There's no way that I could keep the trees in containers above ground during the winter here. I typically sink the plastic container into the ground, but with larger pots made of clay or ceramic, I'm not sure I'd want them in the ground for fear of cracking. Can I remove the root ball from the pot, sink it into the ground over the winter and then repot the tree during the following spring?

By the end of the month, I'll be seeing new leaves like these from last March:
my young Jasemin

Green Cascade

Chioshio Improved

Woods #2

I can't wait to see the new maples unfurl their new leaves, especially Katsura!

Hi Kevin,
I don't see why not it will just be like repotting every year, we do it with our bonsai not every year, but sometimes every two or three years. yes the weather should be warming up soon and we can all look forward to the new growth coming,but it was snowing here yesterday.

Lovely pics now we do not have to wait that long any more :D

My cold winthers :-? Where in UK are you ? You can be in a warmer zone or the same or even colder in UK

I know USDA zones far from perfect, they only shows winther minimum, but they can give an idea :wink:

That's not that far from Denmark

My guess is zone 7b to 8 a or b

Some of my friends drove around in Yorkshire last summer to see if there were as many stone fenches as in the TV trailors The Heartbeat :lol:
Tried to ask about gardens and they just looked at me ... :roll:
