Collapse ▲Lawns are growing like gang busters now that it has finally warmed up. If you haven’t already started fertilizing the lawn for the summer, then now is the time to begin. The lawn is in full swing growing mode and it’s time to give it the building blocks it needs to really grow.
Nitrogen is the main ingredient that plants need to produce green leaves. Since mostly what we want to produce with our lawn is green leaves, nitrogen is the ingredient we need to apply. In most cases, 1 pound of nitrogen per 1,000 square feet of lawn area is what will be required to make that happen.
The soil may be deficient in other nutrients as well. The best way to find out is to take a soil sample and send it to the NCDA&CS Agronomic Services lab and have it tested. Check your favorite garden center to see if they have the boxes and forms needed to take a soil sample for testing.
Many soil samples that I have seen come back over the last couple of years have shown a low potassium level in the soil. Some to the point of needing to add additional potassium in the form of potash as well as a fertilizer with potassium in it. Really, the only way to know is to have the soil tested. If the lawn is looking a little thin or weak, test the soil to see if something extra is needed to reinvigorate the lawn.
If you don’t have an irrigation system, try to time the application of fertilizer so it’s applied a few hours to a day before a good rain event. This will help to permeate the nutrients down into the soil where they can be used by the plants.
