I looked over the trees on Friday and had a trip to the coast planned for Sat. The buds on the maples looked good and I felt I had some time to repot. Good…I can go to Santa Cruz on Sat. and repot the maples on Sunday. Got up Sunday and decided they would wait until next weekend. Big Mistake! Never put off to tomorrow what you can do with your lazy ass.
Came home from work today after a 74 degree day after the small rain storm on Friday and Sat. The buds on the tridents had jumped right over the swelling stage and bolted right to the green leaves unfurling stage. No time to lose, move the table into the yard, get the buckets of soil already made and wire for the pot this is “go time”.
The tree was already in a state that need repotting for sure. The tree was pushing the root pad up and out of the pot.
The tree was unwired from the pot and the whole root pad was lifted from the pot. It was thick as the pot and dense and fiberous. The entire rim of the pad was removed from the tree. In past years I have taken this even shorter to the trunk but this year the nebari is finally improving to the point that cutting back too short means getting into larger roots and I don’t want to disturb those yet.
This is how short the pad was made this year. At this point it still has a small layer of soil on top and the pad is full thickness, about 1.5 inches.
I then rake the bottom of the pad to dislodge the roots from the bottom. These are allowed to hang down and then are trimmed flush with the hard bottom of the trunk.
Now the old soil is raked off and the roots teased for the new soil. At this point the root pad is about 3/4 inch thick. The tree is oriented for aesthetics and then placed directly on the bottom of the pot with out soil. It is wired firmly…I mean firmly, so that it will not push away from the pot. I want all the energy of the first growth spurt to be against a hard surface to get maximum girth on the roots around the tree and to swell at the soil line. The tree at this point is starting to get a good flare at the soil trunk transition and this is due to planting directly on the pot and firm tie in of the tree.
The tree is tied and I can pick it up by the trunk and the pot does not move. The tree at this point still has no soil in it. Just a tree and pot. The soil for the whole tree is backfilled around the depression around the edge of the pot. The soil in the roots from the previous season are not washed from the root mass. This allows the new roots to fill the new area with roots while the roots next to the trunk can inarch and graft together to help form the nebari.
The tree is now backfilled and watered in and placed back on the bench. It will be full of leaves by Friday.
