Fertilize Appropriately

 

Fertilizers can be hazardous to the environment and your yard. When over-applied, fertilizers aggravate pest problems and make plants grow excessively. Excess fertilizer can run off yards into groundwater creating water quality and ecological problems.

1. Use slow release fertilizers so they don’t leach through our sandy soils quickly. 30% water insoluble nitrogen is desirable, it can be labeled as sulfur coated urea (SCU), ureaform (UF), polymer or resin coated urea.

2. Fertilize with light applications 5- 6 times per year.

3. Use ferrous sulfate (chelated iron) instead of nitrogen to make your lawn green in the summer.
