St. Augustine Establishment Guide
St. Augustine CANNOT be grown from seed — no commercially viable seed exists. Three establishment methods: sod (fastest, full coverage day one), plugs (cheapest, 12-inch spacing, fills in 1-2 growing seasons), and sprigs (least common, broadcast and topdress). Best timing: late spring through early summer when soil temps are 70°F+ and the lawn has a full growing season to establish before winter. Sod installation: water 3 times daily for the first 7 days (morning, midday, late afternoon), taper to 2 times daily week 2, once daily week 3, then transition to normal deep-and-infrequent schedule. Do NOT apply pre-emergent for 8-12 months on new sod. For plugs: plant on 12-inch centers, fertilize lightly every 4-6 weeks, keep weeds controlled manually until plugs fill in.
Frequently Asked Questions
What is the best way to establish St. Augustine?
Sod is fastest and most reliable. Lay in spring or early summer for maximum growing season. Plugs work but take 1-2 seasons to fill in at 12-inch spacing. Seed is not an option.
How do I water new St. Augustine sod?
Week 1: water 3 times daily for 15-20 minutes each. Week 2: water twice daily. Week 3: once daily. Week 4+: transition to deep, infrequent watering 2-3 times per week.
Can I apply pre-emergent to new St. Augustine sod?
No. Wait 8-12 months after laying sod before applying any pre-emergent herbicide. New roots need time to establish without chemical interference.
When is the best time to lay St. Augustine sod?
Late spring to early summer when temperatures are consistently warm. This gives the sod the full growing season to root before winter dormancy.
