Fertilization and Soil Management
Sampling and analyzing soil in order to make specific recommendations for each tree or shrub on a property.
Healthy plants begin with healthy soils. Fertilization is just the start. Adjusting soil pH and ensuring adequate organic matter is present are also key to healthy soils. For plants in urban and suburban soils, Bartlett Tree Experts can simulate the optimal conditions for growth found in nature. In fact, our patented Root Invigoration process combines all the above into a single treatment to achieve this goal.
Bartlett offers the most intensive soil management programs in the landscape industry. Before fertilization is prescribed, soil samples are taken from the property and analyzed. Bartlett Arborists submit more than 10,000 soil samples from client properties each year, which provides information for developing fertilizers for specific geographic areas.
We offer more than 15 different blends of our own Boost® fertilizers all of which contain slow-release nitrogen that provides this nutrient gradually over the entire growing season. We developed blends specifically for the West Coast based upon the nutrient status that is typical of soils in the individual areas where Bartlett operates. This means that nitrogen is not lost to leaching and runoff, which optimizes availability, while protecting the environment. If soil phosphorus levels are adequate or treatments are applied in sensitive sites such as watersheds, we use phosphate-free Boost products that are specifically formulated to eliminate water pollution from this nutrient.
