Curling Palmatum leaves...Why?

Mr. Wolfe, the lath cage should be fine if you are sure that it will keep the temperature between 30-40 F throughout the winter.
In the article you mentionned, I was trying to say that I had only one palmatum with two other red maple trees that were mulched in the same box but only the red maples survived.
My motivation to get your tree outside of your apartment is to make sure it starts its dormancy outside before you overwinter it indoors. All temperate trees like maples need a dormant period and with the approach of winter with cooler temperatures it should trigger your tree for this important dormancy period, but should be removed and placed in a cold room well ahead of the dangerous temperatures of the comming winter.

I'd say 3 weeks to a month tops.

I guess we'll see how this thermo-syphon idea works. I have my doubts but hopefully I get lucky. I'm planning on moving out to Vancouver Island next spring, which should be far more maple-friendly.


Must have been a case of wishful reading. Have you had much luck in Zone 4 with palmatum? I'd imagine that St-Hyacinthe on average a little more humid than Calgary, which helps. I was in the area once years ago when I was kid and remember it being fairly windy.


I have feeling that my balconey is going to be too blustery but I'll think of something. Thank you again, M. Devaux.

Since I lost my palmatum from winter killing, I have not tried to bonsai any other japanese maples because I find it too much trouble to overwinter them in a cold room, more so, as they would take more space when they get older. I try to bonsai only native trees, and so far, they do very well with very little winter protection. I also have many species of tropicals and semi-tropicals that spend the winter in my house under fluorescent lights and humidity trays.
St-Hyacinthe may not be more humid than Calgary but certainly very windy during certain periods, but my house is well protected with many tall trees, and this, certainly helps for growing bonsai trees.
Concerning your palmatum, make sure that it stays outside from spring to fall because it will not survive indoor environments for a long time.
