Id like to make a point really quick about all the conversation on "taproot
trees". Unless you are planting a tree from seed, directly into the ground
where the tree is going to grow without being transplanted, you arent going to
get a tree with a taproot. Many trees naturally form taproots, but they are
either broken or purposley removed during the production process. Many nut
trees are known for having taproots, but the walnuts, etc. that you buy in the
nursery have been transplanted usually at least a few times during thier life.
Many growers will purposley use bottomless pots that allow the taproot to grow
out of the soil, dry up, and die. Anyway, dont count on these trees to have a
taproot because most often they will not.
