They contain sufficient vitamins to recover from transplant shock and continue to manufacture them during normal photosynthesis. So Vitamin B 1 does not appear to be the magic bullet. What I am telling you is that information on their usefulness in helping plants recover from transplanting is awfully scanty. As far as we know, using good transplanting technique and plenty of plain old water in the planting hole will be just as effective. If you want to know more about transplanting trees and shrubs, contact your county extension office.
Nursery trees are usually high quality and a good deal, but they are expensive.
Replacing a tree is not only hard work but takes a chunk out of our pocketbooks. To let a young tree be choked out by weeds is a terrible thing, but sometimes controlling those weeds can be worse. Weeds and grass compete with young trees for water and nutrients. If they get tall enough they block sunlight to the tree as well, reducing photosynthesis and weakening tree growth. So we must control the weeds around the tree.
