Thanks!
Noss, the water gets to the roots by wicking. It's the same theory and system that Bill uses and others using self watering pots. But you must have a good mix to ensure the tree is getting water. The soil in the pot goes all the way down to the bottom in the middle, so as long as there is water in the reservoir, the tree will not dry out. Plain ole MG will work fine but All's mix will not....it's too fast draining. I use UPM, MG and I also make my own mix using Peat Moss, Cow Manure, Mushroom compost, Perlite, and lime (not the white fast acting stuff) in a ratio of 2/1/1/1 and a cup of lime. Soil medium will compact so when you add your mix half way, press the center gently to compact it add your tree and add more mix. Like Bill, I mound the soil about 3 or 4 inches above the rim. In other words, sit the tree high in the pot, add your fertilizer and for prettiness add some pine bark. I shower the tree on top with water then I fill from the bottom. I don't move the tree around once I place it unless I really have to. The pine bark keep squirrels out and the bark keep the soil in whenever it rains heavy. And if the tree gets too much water, it simply comes out the refill side. I like these pots. Just wish they were larger.
