Trusted Tree Trimming & Pruning Services in Redding, CA

Assuming you are planting a new tree, it is best to keep a bare patch of ground around the base of the tree as big as the crown, then deep water the tree. Deep watering is to water for a long period of time, but not too often, allowing the top layer of soil to dry out between watering. This causes the roots of a newly planted tree to grow downwards to get water instead of traveling along the surface.

Not if you avoid putting soil (or any other type of debris) against and above the root collar of the tree. The trunk of the tree is not designed to be underground just like the roots are not designed to be above ground. If you put soil above the root collar the tree will most likely get pests, disease, and/or begin to rot, eventually killing the tree.

Again, not an easy question to answer. I think the best answer to this question is to defer it to the nurseryman. A small, but not all-inclusive, list of things to consider are: elevation, soil conditions, water table, surrounding trees, surrounding structures, power lines, and sunlight. All have a bearing on what type of tree you decide to plant.
