Use a plant growth regulator! Mastiff PGR provides desirable growth management while boosting stress and drought tolerance. It is ideal for trees planted too close to houses, sidewalks and power lines or blocking views, anywhere that slower, more condensed growth is desirable. And Pinscher PGR reduces the flowering and fruit or seed production while also enhancing landscape ornamental tree health. A mature Ginko tree that used to produce nearly 100 gallons of seed pods each year requiring extensive cleanup reduced its seed output to less than one quart after being treated annually. Also ideal for messy Crabapples, Walnuts, Sweetgums and more. For more information, click here.
