• What exactly is a certified arborist? An arborist is a highly trained, certified professional who specializes in the cultivation, management, and scientific study of individual trees, shrubs, and woody plants. We possess the deep botanical knowledge required to accurately diagnose diseases, recommend precise structural pruning, and implement treatments that preserve plant health safely.
• Why is there a ring of mushrooms growing around the base of my tree trunk? Fruiting bodies (like mushrooms or large, woody conks) growing near the root flare or directly on the bark of the trunk are often a critical, late-stage warning sign of internal wood decay or severe root rot. You should have an arborist assess the tree immediately, as the structural integrity of the heavy trunk may be completely compromised, making it a falling hazard.
• Do you help select which specific trees to plant in my yard? Absolutely! Selecting the "right tree for the right place" is the most crucial step. We evaluate your yard’s specific soil pH, water drainage, and available sunlight, and we recommend gorgeous native species that will flourish in that exact micro-climate without outgrowing the space or threatening your underground plumbing or overhead power lines.
• What is deep-root fertilization and why do I need it? Instead of just sprinkling granular fertilizer on top of the grass (which the lawn aggressively absorbs long before the tree ever gets to it), we use a specialized metal probe to inject a high-pressure liquid blend of essential nutrients and aerating elements directly into the soil, 8 to 12 inches deep. We put the food right where the tree's microscopic feeder roots actively absorb moisture.
