Before starting the treatment session, clearing the garden of combustible objects is crucial. The category includes dead branches, leaves, haystacks, etc. A standard weed killer torch works best on weeds at 1-2 inches in height (3-5 centimeters). Chemical methods are more suitable for taller weeds. To protect ornamental and valuable plants, keep the flame level low and work through the weeds at a steady pace. The burning process is complete when weeds turn into a matte color. Another factor is the season. Burning weeds in the dry season may pose dangerous fire hazards. For poisonous plants, users need herbicides or manual weeding methods because burning poisonous plants often cause fatal allergic reactions.
