Definition
A type of weed that lives for many seasons. Perennial weeds are a flowering weed that can produce both by seeds and by the spread of energy-storing vegetative parts, such as roots or tubers. Regeneration by vegetation is a unique characteristic to perennial weeds, meaning even the smallest root or stem can reproduce an entire plant. Proper lawn care when removing perennial weeds includes removing the entire root system or the use of certain herbicides. Another method to avoid perennial weeds is prevention through appropriate yard care.
