Weed Control

Pennsylvania at Greenwood, uses a 27% aromatic hydrocarbon mineral spirits on all conifers and larch. Black alder and yellow poplar beds are planted after several sprays to kill emerging weeds. At emergence, while these seedlings are still young they may be sprayed with only minor losses. This system permits 2 hand weeding per year instead of 4. Weed control with mineral spirits has been so successful that no search has been made for other chemicals.
