Weeds are a symptom. A thin, struggling lawn lets them in, and spraying alone never really wins. Blue Tree controls weeds the way that lasts: targeted treatment to knock down what is there, plus a healthy, thick lawn that keeps them from coming back. For 43 years, Blue Tree has cleared and kept lawns across Southeastern Pennsylvania.
Most weed control is just a tank of herbicide on a calendar. Blue Tree treats weeds as part of overall lawn health. We use pre-emergent to stop crabgrass and annual weeds before they sprout, target broadleaf weeds like dandelion and clover where they actually are, and feed the turf so it thickens and crowds weeds out on its own. A turf professional reads the lawn each visit and adjusts. That combination beats spraying year after year and never fixing the cause. Mark Peasley's team has handled weeds across Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties since 1983.

Fertilization Program. A thick, fed lawn is the best weed control there is. Explore fertilization programs.
Aeration and Overseeding. Thicken the turf so weeds have nowhere to start. Explore aeration and overseeding.

Weed control is usually part of a season-long Blue Tree program rather than a one-off spray, with applications running from about $50 to $90 each for a typical lawn and a full season often totaling $400 to $800 or more, as of 2026. Lawn size and weed pressure affect the price. Every program starts with a free assessment and a clear plan.
Because spraying only treats the symptom. Weeds invade thin, stressed turf, so if the lawn never thickens up, new weeds keep moving in. Blue Tree pairs targeted weed control with feeding and density so the lawn itself crowds weeds out. That is why a program beats one-off spraying that never fixes the cause.
Pre-emergent creates a barrier that stops weed seeds, mainly crabgrass, from germinating. The timing is critical: it has to be applied in early spring before the soil warms enough for crabgrass to sprout, usually around forsythia bloom in our region. Blue Tree times it to the season, which is most of the battle against crabgrass.
No, when it is done right. Blue Tree uses selective products that target weeds while leaving turf grass unharmed, applied at label rates by trained professionals. Blanket-spraying the wrong product or rate is what damages lawns, which is exactly why it is worth having a program handled by a turf professional.
Blue Tree applies products per label directions and recommends a short stay-off period after each treatment, usually until the application has dried or as the label specifies. Your turf professional will tell you exactly how long to keep kids and pets off after each visit.
