Fertilize irrigated lawns in May _ If you water your fescue or Kentucky bluegrass lawn in summer, plan to fertilize this month. If you don't water, the lawn probably will go into dormancy at some point during the summer and won't need the fertilizer, Ward Upham of K-State says.
It's best to use a slow-release fertilizer this time of year. It's harder to find than quick-release types. Milorganite is one slow-release fertilizer, as are cottonseed meal, alfalfa-based fertilizers, and any other products derived from plants or animals, Upham says. (Bloodmeal is an exception.) These fertilizers are more expensive, because you have to use more of them to get the amount of nitrogen you need.
I'll let Upham explain it: "Apply enough to give the lawn one pound of nitrogen per 1,000 square feet. For example, if the fertilizer is 6 percent nitrogen by weight, you will need to apply almost 17 pounds of fertilizer product per 1,000 square feet. Summer lawn fertilizers that contain at least a portion of the nitrogen as slow-release are fine to use as well. Be sure to follow label directions.
"If cost is prohibitive, you can use the less expensive quick-release (i.e., soluble) sources, but split the application into two doses as follows: Apply enough to give the lawn half a pound of nitrogen per 1,000 square feet in May and again in early June."
Planting calendar _ I'm waiting for the nighttime temperatures to get out of the 40s, which hopefully will be just a couple more nights, to plant these plants that like it a little warmer: tomatoes, eggplant, peppers, basil and other herbs. Seed directly in the ground cucumbers, okra, melons and summer squash including zucchini.
