Thruout the winter, nite temperatures in the mudroom stayed consistently about 10° F (5.6° C) above the outdoor temperatures. Daytime temperatures in the mudroom would often get warmer than the outdoors by more than 10° F, especially on clear days with the sun shining thru the south-facing window. The effect has been what I wanted: the trees in the mudroom have had a milder winter than their hardy counterparts outside. And now they are having an earlier spring: as I write, all but the bald cypress have broken dormancy.
Half a dozen of them were due for repotting this year, and I spent some very enjoyable hours this past weekend doing just that. (Outdoors, too! ☺) Here's a picture of the weekend's haul.
|Repotted on March 10 and 11.|
All these trees are still in development, and all were potted on -- i.e., potted into containers a little larger than they had been in before. All the maples are potted in what I call "goulash:" a general blend of bark, Turface, granite grit, and some perlite; proportions are judged by eye, and most of the ingredients are recycled, after first being re-sifted to remove fine particles. The pine is in a more exact mix of scoria (usually sold as "lava,") bark, and Turface, in proportions of 5:3:2.

Me: "There were lots of new white root tips. It was beautiful!"
She (after a half-second pause): "Um, OK."
Me (laughing): "Well, beautiful to a bonsaiist!"
