Steps for Broadleaf W**d Control In St. Augustine Lawns
The month of April seems to bring about one common question from homeowners..."How can I eliminate w**ds in my st. augustine lawn?"
Here are 7 simple steps:
1. Maintain proper mowing height
• Mow at about 3–4 inches, which is typically the recommended range for St. Augustine grass.
• Cutting too short weakens the lawn and makes it easier for broadleaf w**ds to take hold.
2. Water correctly
• St. Augustine likes thorough, less frequent watering, typically about one inch per week (depending on rainfall).
• Overwatering can encourage w**d germination; underwatering stresses the turf, giving w**ds a foothold.
3. Fertilize appropriately
• Follow a balanced fertilizer schedule to keep St. Augustine dense and competitive.
• Too little fertilizer stunts grass growth; too much (especially nitrogen) can encourage w**ds and disease.
• Soil tests help identify nutrient deficiencies and guide proper fertilizer application.
4. Hand-pull when w**ds are few
• If only a few w**ds appear, pull or dig them up before they drop seeds.
• Removing w**ds early prevents them from multiplying and protects your lawn’s overall health.
5. Apply pre-emergent herbicide if needed
• A pre-emergent herbicide in early spring can help prevent new w**d seeds from sprouting.
• Look for products labeled as safe for St. Augustine lawns. Always follow instructions carefully.
6. Use the right post-emergent broadleaf herbicide
• When a post-emergent treatment is necessary, choose products specifically labeled for use on St. Augustine.
• Some broadleaf herbicides (e.g., those with 2,4-D) can damage St. Augustine if used incorrectly or at too high a concentration.
• Spot-treat individual w**ds or patches rather than blanket-spraying the entire lawn, unless the label directs otherwise.
7. Maintain lawn health year-round
• Follow best practices consistently—proper mowing, watering, and fertilization—so the turf naturally suppresses w**ds.
• Keep lawn equipment clean to avoid spreading w**d seeds or diseases.
