One-Time Services

Immediate correction for weeds, pests, fungus, or nutrient issues.

The Short Answer

For a one-time fix in Conroe or The Woodlands, TX GrassRX offers single-visit treatments for weeds, fungus, pests, and nutrient issues on St. Augustine lawns, starting around $149. One-time services work for immediate correction, but the best long-term results come from a monthly program that times every treatment to the Texas growing season.
