Tree shelters

Tree shelters, hollow plastic tubes about 3 inches diameter, can speed shoot growth of small seedling trees but some tree species develop weak trunks and small root systems and are unable to hold themselves erect (Kjelgren 1994; Burger et al. 1992). Trees can be enclosed in wire or mesh screening to keep out deer. Some horticulturists slice a 6 to 12-inch-long section of black plastic drain pipe so it can be slipped around the lower trunk. Others use plastic trunk guards which can be spiraled around the trunk and lower branches or other specially designed devices for trunk protection.
