caterpillar_crossingPlant Health Care and Integrated Pest Management are two approaches pioneered by Baefsky in urban landscapes, resulting in greater health, safer and more beautiful landscapes. Properly matching up plants, light, soil and water avoids pest, disease and weed problems. Monitoring landscapes to detect early cues of problems saves money and plants for property managers & homeowners.  Tweaking maintenance practices halts disease infections and pest infestations that lead to dead and dying landscapes. Ecological design, early intervention and ongoing maintenance monitoring is how we promote safer and healthier landscapes.
