Sweet spring — This has been a turning-point week, with sustained warmth, sunshine and nighttime temperatures finally out of the 40s. The days have been gorgeous, the evenings pristine. The fragrance of iris floats on the air, and it’s stunning to see combinations such as china-pink roses interposed with white irises, or a stand of yellow irises where no color existed before. The garden fever is definitely picking up with the temperatures, and Herb Day, and Mother’s Day this weekend.
Fescue fertilizer — Cool-season grasses such as fescue and bluegrass can be fertilized in May if you plan to water through the summer. Otherwise, the grass will probably go through some dormancy and won’t need this fertilization, Ward Upham of K-State says. Slow-release nitrogen is the best, which is found most commonly in Milorganite. “Apply enough to give the lawn one pound of nitrogen per 1,000 square feet,” Upham writes in the Horticulture 2016 newsletter. “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.” Apply enough to give the lawn 1/2 pound of nitrogen per 1,000 square feet in May and then in early June, Upham writes.
Plant — Beans, cucumbers, eggplant, melons, peppers, okra, pumpkins (plant closer to July 4 for a Halloween harvest), salsify, sweet corn, tomatoes, squash.
