- Feed your lawn now. A slow release fertilizer like a 19-5-9 ratio is best. It slowly feeds throughout the growing season and does not wash into the ground water.
- If your lawn is a little yellow (chlorotic), use six tablespoons of iron sulfate dissolved in one gallon of water used as a spray. It will green your lawn up fast. Use green sand later, as a long term preventative in late April and again in mid-October.
- Use a water-soluble complete-and-balanced (20-20-20) plant food for the first four waterings of recently planted annuals and perennials.
- To control weeds in bermudagrass, use MSMA after temperatures have risen above 80 degrees F. For adult weed control in St. Augustine, use Wipeout.
- Maintain your roses with a spray program. Use Orthonex every ten to fourteen days throughout the growing season.
