St. Augustine waters are a precious resource, and it’s important to keep them clean and healthy. One way to do this is to fix stormwater runoff from the shore. Stormwater runoff can carry pollutants into our waterways, harming aquatic life and damaging the environment. By taking steps to fix stormwater runoff, we can help protect our waters and ensure a healthy future for our community. Some of the entities involved in fixing stormwater runoff include local governments, environmental organizations, businesses, and residents.

Coastal Challenges for St. Augustine Grass
Salt Water Tolerance:
Coastal environments present unique challenges for St. Augustine grass due to its sensitivity to salt. Saltwater intrusion can damage the grass’s roots, reducing its ability to absorb water and nutrients. This can lead to stunted growth, yellowing of leaves, and ultimately plant death.
Sandy Soil Conditions:
Coastal areas often have sandy soil, which can also pose challenges for St. Augustine grass. Sandy soils are well-drained but can quickly lose moisture, making it difficult for the grass to establish a strong root system. Additionally, sandy soils are prone to nutrient leaching, which can further hinder grass growth.
Drainage Issues:
Poor drainage is another common problem in coastal areas. Tidal surges and excessive rainfall can waterlog the soil, creating anaerobic conditions that suffocate grass roots. This can lead to the development of disease and other lawn problems.
Environmental Factors Affecting St. Augustine Grass Health on the Coast
Navigating Coastal Challenges
Coastal environments present unique hurdles for St. Augustine grass due to its sensitivity to certain environmental factors.
Tidal Surge
- Impact: Saltwater intrusion can damage grass roots, stunt growth, and burn leaves.
- Prevention and Mitigation: Plant grass varieties tolerant of salt water. Create barriers with sand dunes or bulkheads to deflect surge. Improve drainage to prevent waterlogging.
Drought
- Impact: Extended dry spells can cause stress, wilting, and thinning.
- Prevention and Mitigation: Establish a proper watering schedule. Mulch around the grass to retain moisture. Aerate the soil to improve water penetration.
Erosion
- Impact: Wind and water can erode soil, exposing grass roots and damaging the lawn.
- Prevention and Mitigation: Plant groundcovers or erosion control grasses to stabilize the soil. Use sand fences or erosion mats to protect against wind erosion. Replenish lost soil with a top dressing.
Strategies for Coastal Grass Care
Professional Expertise
- Consult with a professional landscaper who specializes in coastal grass care.
- They can provide personalized guidance based on your specific environmental conditions.
Homeowner Responsibilities
- Watering: Water deeply and infrequently to encourage deep root growth.
- Fertilization: Apply fertilizer as recommended by a soil test to provide essential nutrients.
- Weed Control: Keep weeds under control to prevent competition for water and nutrients.
- Pest and Disease Management: Monitor for pests and diseases and apply appropriate treatments as needed.
Essential Chemical Applications for Coastal St. Augustine Grass
Maintaining a vibrant and healthy St. Augustine lawn in coastal environments requires a comprehensive approach that includes proper fertilization and pest and disease control.
Fertilization
Fertilizers: Fertilizers provide essential nutrients for grass growth and health. Select a balanced fertilizer with a slow-release formula to avoid nutrient burn. Choose fertilizers specifically designed for coastal grasses, which may contain additional nutrients, such as potassium and iron, to enhance salt tolerance.
Frequency: Fertilize St. Augustine grass every 4-6 weeks during the growing season. Adjust fertilization rates based on soil test results.
Fungicides
Types of Fungicides: Fungal diseases are common in coastal environments due to the combination of humidity and salt spray. Use broad-spectrum fungicides to control a wide range of diseases, including brown patch, dollar spot, and gray leaf spot.
Application: Apply fungicides as a preventative measure or at the first sign of disease. Follow the manufacturer’s instructions carefully and use only products labeled for use on St. Augustine grass.
Herbicides
Selective Herbicides: Herbicides can effectively control weeds that compete for nutrients and water. Use selective herbicides that target specific weed species without harming the grass.
Non-Selective Herbicides: Non-selective herbicides kill all vegetation and are used for weed control in areas where complete vegetation removal is desired.
Application: Apply herbicides according to the manufacturer’s instructions. Always wear protective gear and take precautions to avoid chemical exposure.
Maintaining a Thriving Coastal Lawn: Professional Expertise and Homeowner Responsibilities
When it comes to coastal lawn care, professional expertise can guide you towards a lush and verdant landscape. Consulting with certified landscapers is highly recommended, especially in areas where environmental factors pose unique challenges. Their extensive knowledge and experience will ensure your St. Augustine grass thrives despite the coastal elements.
As a homeowner, your responsibilities extend beyond watering and mowing. Educating yourself on proper maintenance practices is crucial to preserving your lawn’s health. This includes:
- Understanding the specific nutritional needs of coastal grasses and adjusting your fertilization schedule accordingly.
- Recognizing and treating common pests and diseases that may affect St. Augustine grass in coastal environments.
- Implementing proactive measures to mitigate the effects of erosion and drainage issues.
By working in tandem with professionals and assuming your own responsibilities, you can create a beautiful and resilient coastal lawn. Avoid costly mistakes and ensure the longevity of your verdant oasis by seeking expert advice and maintaining an informed approach to home lawn care.
