Using Roundup near conifers
Greetings all. Can anyone tell me how resistant young conifers (3-5 feet tall) are to products like Roundup (glyphosate)? I'd like to get rid of weeds and grass around and near the conifers but am uncertain whether Roundup would harm or even kill them. Most are blue spruces, white spruces, concolor firs, Serbian spruces and Eastern white pines.
