Some weed control may be necessary, particularly in richer soils. The trees and shrubs you plant will be competing with weeds for soil nutrients, moisture, and fertilizer. You may want to eliminate this problem with herbicides and/or mowing. Maintaining the area that surrounds your seedlings is an important part of survival rates. Like anything else, the more work you are willing to put into it, the better results you will get out of it.
