Overview

St. Augustine grass is a warm season perennial lawn grass that is most commonly planted by sheet sod or sod plugs and very rarely by seed. According to Texas A&M University, very few strains of St. Augustine grass are fertile, making vegetative propagation the key means of growing the grass. St. Augustine plugs can be planted during any part of the year, provided that you can keep them and the surrounding soil constantly moist.

Step 1

Prepare a well-tilled planting bed amended with a lawn starter fertilizer rich in phosphorous with guaranteed analysis of 18-24-6 or a similar ratio. Mix the grains into the top 3 to 5 inches of soil using the dose recommended for your acreage of lawn to be plugged.

Step 2

Plant St. Augustine grass plugs that are 2 to 4-inches square in the soil at intervals of 1 to 2-feet. Plant so the roots are completely buried in the soil but the top of the thatch and green blades remain above grade. Firm the soil around the roots of each plug to secure upright in the soil.

Step 3

Water the plugs and surrounding soil until drenched with water to a depth of 5-inches. Keep the plugs and soil constantly very moist until the plugs are well-rooted in the soil and beginning to grow towards one another.

Step 4

Feed your St. Augustine plugs once a month with a nitrogen-rich lawn fertilizer product. Apply according to the product label directions, but do not exceed a rate of 1 lb. of actual nitrogen for every 1,000 square feet of plugged area. Water it well after each application.
