If you’re wondering what the best thing to put on St. Augustine grass is, the answer is a combination of proper watering, fertilization, and care. This warm-season grass thrives in southern climates but needs a little TLC to stay lush and green. Here’s how to give your lawn the best shot at thriving.
Watering
Watering is crucial for St. Augustine grass. Aim for deep, infrequent watering rather than shallow, frequent sprays. Here’s what you need to know:
Frequency
- Spring: Water 2-3 times a week as the grass wakes up from dormancy.
- Summer: Increase to 2-4 times a week depending on soil type and weather conditions.
- Autumn: Cut back to 1-2 times a week as temperatures drop.
Technique
Water early in the morning to reduce evaporation and prevent fungal diseases. If your grass starts looking bluish or doesn’t bounce back when stepped on, it’s time for a drink!
Fertilization
Fertilizing your St. Augustine grass helps maintain its vibrant color and health. Here are some tips:
Types of Fertilizer
- Weed and Feed: Use a St. Augustine-safe weed and feed fertilizer about two weeks before you expect growth in spring.
- Iron Supplements: If your grass looks pale, an iron supplement can help green it up without promoting excessive growth.
Schedule
- Fertilize in spring, then again about ten weeks later during summer. An autumn blend can be applied as temperatures cool down.
Mowing
Mowing isn’t just about keeping things tidy; it’s essential for your grass’s health too.
Height
Keep your mower set between 2 to 4 inches depending on the variety of St. Augustine you have. Remember the ⅓ Rule: never cut more than one-third of the blade at once.
Clippings
Leave clippings on the lawn as they decompose and return nutrients back into the soil—nature’s way of fertilizing!
Dethatching and Aeration
Over time, thatch can build up, blocking water and nutrients from reaching the roots.
Dethatching
If you notice more than an inch of thatch, it’s time to dethatch! This can be done with a dethatching machine during spring or early summer.
Aeration
Aerate if your lawn sees heavy foot traffic or has compacted soil. This process allows air, water, and nutrients to penetrate deeper into the soil.
