Lawn, Warm Season (Bermudagrass, Zoysia)

One

Section A.

Establishment (bermuda, Zoysia, centipede): For bermuda, apply 25 lbs. of 6-12-12 at seeding, sprigging only, or 19 lbs of 8-8-8 or 15 lbs. of 10-10-10 or 10 lbs. of 15-15-15 per 1000 sq. ft. at seeding or sprigging and again six weeks later. At each application, use 25 percent less fertilizer for Zoysia or 50 percent less fertilizer for centipede fertilization. A slow release (60 day) form of nitrogen may give best results. Select an appropriate maintenance schedule (see section B below) and begin following that schedule the very next spring season after lawn establishment, until you soil test again.

Section B.

Maintenance of Established Lawns (bermuda, Zoysia, centipede): Choose one level of maintenance to follow. The lowest maintenance level will require less frequent mowing but may be more weedy and not always maintain the quality of lawn desired. Your soil P and/or K levels are low to medium. These fertilizer maintenance levels should, over time, build your soil out of the low testing range for P and K. However, if grass clippings are continually removed, K levels may stay in the low or medium testing range. This is normal, but increases the importance of not missing any of the maintenance applications.

I. Highest Level Maintenance of an established lawn (Availability and Proper Use of Irrigation is preferred when using this maintenance level): For bermuda (1) Topdress annually Apr. 15 and and Sept. 1 with 13 lbs of 8-8-8 or 10 lbs. of 10-10-10 or 7 lbs. of 15-15-15 per 1000 sq. ft. (2) Topdress annually June 1 and July 15 with 6.2 lbs of 16-4-8 or 3.5 lbs. of 34-0-0 or 30-3-4 or 28-3-3 or 29-3-4 or 28- 4-6 or other fertilizer material of a similar ratio (very low P and K content) per 1000 sq. ft. If the fertilizer material contains at least 30 percent of a slow release (60 day) form of nitrogen then the June and July applications may be combined and spread as one application in June. For Zoysia, use 25 percent less fertilizer at each application, as indicated above for bermuda. For centipede, fertilize only in Apr. and July using the same materials and rates indicated above for bermuda in those months. Follow this schedule for 2 growing seasons, then soil test again.

II. Medium Level Maintenance of an established lawn: For bermuda (1)Topdress annually Sept. 1 and Apr. 15 and June 1 with 13 lbs of 8-8-8 or 10 lbs. of 10-10-10 or 7 lbs. of 15-15-15 per 1000 sq. ft. At each application, use 25 percent less fertilizer for Zoysia fertilization. For centipede fertilize only in Apr. and July using 25 percent less fertilizer than suggested above for bermuda in Apr. If the fertilizer material contains at least 30 percent of a slow release (60 day) form of nitrogen then the Apr. and June applications may be combined and spread as one application in Apr.  Follow this schedule for 3 growing seasons, then soil test again.

III. Lowest Level Maintenance of an established lawn: For bermuda (1) Topdress annually Apr. 15 and June 1 with 13 lbs of 8-8-8 or 10 lbs. of 10-10-10 or 7 lbs. of 15-15-15 per 1000 sq. ft. A fertilizer containing at least 30 percent of a slow release (60 day) form of nitrogen may give the best results. Use 15 percent less fertilizer for Zoysia and 30 percent less fertilizer for centipede fertilization. Follow this schedule for 4 growing seasons, then soil test again.
