Weed Control in Christmas Trees - E3237
Weeds compete with Christmas trees for nutrients, water, space, and light, and can harbor pests and pathogens. Weeds interfere with tree growth at every stage of production and every time of year. When left unchecked, weeds can reduce the growth of Christmas trees by 50% (Warren et al., 1987).
In this bulletin we will discuss nonchemical and chemical weed control methods, herbicides that are labeled for use in Christmas trees, herbicide-resistant weeds, and the potential negative effects of herbicides on the environment.
