Deep root fertilization is a managed fertilization procedure that requires delivering the feed straight to the root-system. Unlike conventional fertilization techniques that distribute feed onto the treeâs area, the deep root fertilization procedure distributes the feed beneath the soilâs surface close to the roots. Commercial landscapers use high powered products for the procedure. However, it is possible to recreate the procedure for house use without without the need for high powered products.
Dig holes that are slim round the tree or drill holes having a power auger. Create the holes across the diameter of the tree, putting the holes. Keep the holes at least 6 to 12-feet in the root of the tree and make the holes about 8 to 12-feet deep. Create an outer circle of holes which are in-line using the treeâs drip line. So it’s readily accessible to refill the holes place the soil apart each hole.
Purchase a slow release, fluid fertilizer for the deep-root fertilization procedure. Select a well balanced liquid feed, including a 10-10-10 mixture, that contains mycorrhiza, as this encourages a robust root system-while decreasing the treeâs susceptibility to soil pollutants. Enough fluid feed to fill each hole that is ready with 1/2 gallon of fertilizer.
Fill each hole with around 1/2 gallon of fluid. Pour the feed into each hole. Until each hole is handled the filling procedure. After the fluid feed absorbs refill each hole with soil.
