Lawn Care Calender
March
· Use broadleaf herbicides for perennial and winter annual weeds not controlled in the fall. This can be combined with a Spring fertilizer that has a pre-emergent (before weeds start) herbicide coating that releases with heat and rain.
· Overseed thin spots early if missed last fall.
· Watch for leaf spot and mildew diseases.
· Aerate if thatch is heavy or soil is compacted.
· Use crabgrass preventers by April 15.
· Fertilize as rapid spring growth begins to slow.
· Apply post emergence broadleaf herbicides for summer weeds. If needed, start post emergence control of crabgrass, goose grass or nut sedge near the end of the month.
· Start watering as needed. Water infrequently to a depth of 6 inches. Don’t overwater, as that can promote fungal growth, but water frequently enough to prevent drought stress.
· Fertilize and pre-treat for Bill Bug infestation using a systemic.
· Irrigate two to three times a week as soil absorption allows. Avoid frequent, daily irrigation.
· Search for white grubs in brown areas. Dead turf in those areas easily can be peeled from the surface. If 5 to 10 grubs appear in 1 square foot you need to treat it.
· This is the most important time to fertilize - Use a well-balanced lawn fertilizer
· Late September is the best time for broadleaf herbicides, especially for perennial broadleaf weeds.
· Fertilize moderately after cool days slow leaf growth. Nutrients at this time will encourage root growth and thickening of turf. Soluble nitrogen fertilizers are used more efficiently by turf in late Fall.
