Ultimate Spring and Summer Care Guide for St. Augustine Grass
Homeowners across Jacksonville’s beaches community trust Rockaway Sustainable Landscaping to show them how to care for St. Augustine grass the right way. This warm-season grass thrives in our coastal climate, yet it rewards owners who follow a simple seasonal plan. To keep your lawn looking its best, we’ve put together a St. Augustine grass care guide, complete with practical lawn care and maintenance steps for a healthy, green yard you can enjoy year-round.
Understanding St. Augustine Grass
St. Augustine grass loves heat, humidity, and the sandy soils found near the coast. Its broad blades create a thick, carpet-like surface that feels soft underfoot. The grass spreads through above-ground runners, filling in bare spots fast. With steady water, sunlight, and feeding, it stays lush across both residential lawns and commercial properties throughout coastal Northeast Florida.
Spring Lawn Care for St. Augustine Grass
Spring sets the stage for a strong growing season. As temperatures climb, your lawn wakes up and needs a few focused tasks to bounce back:
- Fertilize When Warm – Apply a balanced fertilizer once soil temperatures stay above 65 degrees. This feeds new growth and restores color after winter dormancy.
- Weed Control – Use a pre-emergent product early to stop weeds before they sprout. Healthy turf also crowds out unwanted plants naturally.
- Tall Mowing – Begin regular mowing at a height of 3 to 4 inches. Taller blades shade the soil and protect roots.
- Irrigation Checks – Test your sprinkler system for leaks and even coverage. Spring is the ideal time to fix any issues before summer heat arrives.
Summer Care Guide for St. Augustine Grass
Summer brings intense sun and frequent storms to Florida, especially if you’re in coastal spots like Atlantic Beach or Ponte Vedra. Smart lawn maintenance during these months keeps your grass green without wasting water:
- Deep Waterings – Water deeply but less often, ideally in the cooler mornings, giving your lawn about an inch per week. This encourages strong, deep roots for your yard.
- Monitor Pests – Watch for chinch bugs and grubs, which thrive in summer heat. Early action prevents widespread damage.
- Sharp Mower Blades – Keep blades sharp for clean cuts. Torn grass turns brown and invites disease.
- Grasscycling – Leave clippings on the lawn to return nutrients to the soil. This simple habit reduces fertilizer needs and supports a natural ecosystem.
The 3 Rules of St. Augustine Grass Care
A few core habits make the biggest difference for your turf. Master these three rules, and your lawn will stay healthy through every season:
- Mow High and Light – Cut at 3 to 4 inches to protect roots and shade out weeds. Never remove more than one-third of the blade at once.
- Water Wisely – Water early in the morning to limit evaporation and fungus. Deep, infrequent watering beats daily light sprinkling.
- Fertilize on Schedule – Fertilize your lawn during the active growing seasons of early March for steady color. Follow product rates and our other fertilizer tips to avoid overfeeding.
Essential St. Augustine Grass Maintenance Tips
Consistent care keeps your lawn looking its best year-round. These habits work well for homes in Jacksonville and Neptune Beach alike:
- Aerate Yearly – Loosen compacted soil once a year to improve air and water flow. Roots grow stronger with better access to oxygen, so keep an eye out for the signs your soil needs aeration.
- Test the soil – Check soil pH every couple of years to guide your fertilizer choices. Balanced soil supports better nutrient uptake, especially for more coastal homes.
- Manage Shade – Trim nearby branches to let more light reach the grass. St. Augustine grass needs several hours of sun daily, so keep it clear and unobscured for most of the day.
- Repair Bare Spots – Plug or sod thin areas promptly. Quick fixes keep weeds from moving in.
Common Mistakes to Avoid
Even careful homeowners slip up sometimes, especially if they’re busy. Be sure to avoid these common errors to help your lawn stay thick and green:
- Overwatering Your Lawn – Too much water leads to shallow roots and fungus. Stick to a measured weekly amount instead, based on what your plants need.
- Cutting Too Short – Scalping, or cutting the grass too short, can stress the plant and your lawn’s health.
- Skipping Pest Checks – Ignoring early pest signs allows damage to spread. Regular inspections catch problems sooner.
- Wrong Fertilizer Timing – Feeding during dormancy wastes product and money. Be sure to time your applications with the active growth seasons of spring, so you can revive plants after a freeze.
