Caring For Your St. Augustine Grass All Year
Simple Yearly Schedule
Spring: March to May
- Mowing: Start mowing your St. Augustinegrass lawn regularly as temperatures rise, following the "one-third rule" to avoid stressing the grass. Set your mower to a height of 3.5 to 4 inches to promote deeper root growth and shade the soil, reducing water evaporation.
- Fertilization: Apply a slow-release, phosphorus-free fertilizer in accordance with GI-BMP guidelines to minimize nutrient runoff and protect water quality. Consider soil testing to determine specific nutrient needs and avoid over-fertilization.
- Weed Control: Implement integrated pest management (IPM) strategies for weed control, including hand-pulling, mulching, and spot-treating with herbicides only as a last resort. Use herbicides labeled safe for St. Augustinegrass and apply them judiciously to minimize environmental impact.
- Irrigation: Practice efficient irrigation techniques such as cycle and soak to prevent runoff and promote deep root penetration. Adjust irrigation schedules based on weather conditions and moisture levels to avoid overwatering and conserve water.
Summer: June to August
- Mowing: Continue mowing your St. Augustinegrass lawn at the recommended height, adjusting frequency as needed to prevent scalping and maintain turf health. Leave grass clippings on the lawn to return nutrients to the soil.
- Fertilization: Apply a slow-release, nitrogen-only fertilizer formulated for summer use, following GI-BMP guidelines to prevent nutrient leaching and runoff. Consider using organic fertilizers to promote soil health and microbial activity.
- Weed Control: Monitor your lawn regularly for weeds and address them promptly using non-chemical methods whenever possible. Hand-pull or use mechanical weeders to remove weeds, and minimize herbicide use to protect pollinators and beneficial insects.
- Irrigation: Adjust irrigation schedules to account for increased evaporation rates and rainfall patterns during the summer months. Water deeply but infrequently, aiming for approximately 1 to 1.5 inches of water per week, and irrigate during early morning hours to minimize water loss to evaporation.
Autumn: September to November
- Mowing: Gradually lower the mower height as temperatures cool, but maintain a sufficient grass height to shade the soil and reduce weed germination. Consider overseeding with perennial ryegrass for a green lawn throughout the winter.
- Fertilization: Apply a potassium-rich, slow-release fertilizer to promote root growth and winter hardiness, following GI-BMP recommendations for nutrient application rates and timing. Avoid fertilizing before heavy rainfall to prevent nutrient runoff.
- Weed Control: Continue weed management practices such as hand-pulling and mulching, and use herbicides sparingly and selectively as a last resort. Focus on preventing weed seed production to minimize future infestations.
- Irrigation: Adjust irrigation schedules to match seasonal rainfall patterns and cooler temperatures, reducing watering frequency as grass growth slows. Monitor soil moisture levels and water only when necessary to promote deep root growth and drought tolerance.
Winter: December to February
- Mowing: Maintain regular mowing as needed to keep the lawn tidy, but avoid mowing when the grass is wet to prevent compaction and disease spread. Consider leaving grass clippings on the lawn to provide organic matter and nutrients.
- Fertilization: Apply a winterizing fertilizer with low nitrogen content to avoid stimulating excessive growth during dormancy. Focus on potassium and micronutrient supplementation to support root health and prepare the lawn for spring growth.
- Weed Control: Continue monitoring for weeds and addressing any emerging issues using non-chemical methods whenever possible. Maintain a healthy lawn through proper cultural practices to minimize weed competition.
- Irrigation: Reduce irrigation frequency during the winter months, watering only as needed to prevent grass from drying out. Water deeply but infrequently, adjusting for seasonal rainfall and temperature fluctuations.
Year-Round Tips
- Disease Prevention: Keep an eye out for signs of common St. Augustinegrass diseases such as brown patch and gray leaf spot. Proper watering, mowing, and fertilization practices can help minimize disease risk.
- Pest Management: Monitor for pests like chinch bugs and sod webworms, which can damage St. Augustinegrass lawns. Treat infestations promptly with insecticides labeled for use on St. Augustinegrass.
- Aeration: Consider aerating your lawn annually, especially if the soil is compacted. Core aeration improves soil drainage and allows air, water, and nutrients to reach the grass roots more effectively.
- Soil Health: Prioritize soil health by incorporating organic matter through mulching, composting, and topdressing to improve soil structure and fertility.
- Water Conservation: Practice water conservation by using rain barrels, installing low-flow irrigation systems, and incorporating drought-tolerant landscaping features to reduce water usage.
- Native Plants: Consider incorporating native plants and grasses into your landscape to enhance biodiversity, attract pollinators, and reduce maintenance requirements.
By following this detailed yearly schedule and integrating GI-BMP practices and Florida-Friendly principles into your lawn care routine, you can cultivate a vibrant and sustainable St. Augustine grass lawn that enhances the beauty of your outdoor space while minimizing environmental impact.
Why should I care?
Unraveling Florida's Weed Diversity
Florida, known for its sunny weather and lush landscapes, offers a unique environment for gardening and landscaping. However, the state's climate can also present challenges for maintaining vibrant outdoor spaces. In recent years, there has been a growing movement towards "Florida Friendly" landscaping techniques – methods that not only enhance the beauty of your surroundings but also promote sustainability and conserve precious natural resources. Understanding Florida's Climate Before diving into Florida Friendly landscaping techniques, it's essential to grasp the distinct climate of the region. Florida experiences hot and humid summers, mild winters, and often heavy rainfall, particularly during the summer months. These conditions can influence plant selection, watering schedules, and overall garden maintenance practices. Key Principles of Florida Friendly Landscaping Water Conservation: Given Florida's frequent rainfall coupled with periods of drought, efficient water usage is paramount. Incorporating drought-tolerant plants, installing rain barrels or cisterns, and utilizing drip irrigation systems can help minimize water waste while keeping landscapes thriving. Native Plants: Choosing native plants adapted to Florida's climate not only ensures they can withstand the weather conditions but also supports local ecosystems. Native plants typically require less water, fertilizer, and pesticides compared to exotic species, making them a sustainable choice for landscaping projects. Soil Health: Healthy soil is the foundation of a flourishing landscape. Testing soil quality and incorporating organic matter such as compost can improve nutrient levels and water retention, reducing the need for synthetic fertilizers and enhancing plant resilience. Right Plant, Right Place: Selecting plants suited to their specific growing conditions – including sunlight exposure, soil type, and moisture levels – is essential for their long-term success. Proper placement can minimize maintenance requirements and promote healthy growth. Wildlife Habitat: Creating habitats for native wildlife enhances biodiversity and contributes to a thriving ecosystem. Incorporating elements such as bird feeders, butterfly gardens, and pollinator-friendly plants not only adds aesthetic appeal but also supports local fauna. Practical Tips for Florida Friendly Landscaping Xeriscaping: Embracing xeriscaping principles – which focus on low-water landscaping – can significantly reduce water consumption while maintaining attractive outdoor spaces. Incorporate drought-tolerant plants, mulch beds to retain moisture, and group plants with similar water needs together. Integrated Pest Management (IPM): Implementing IPM strategies reduces reliance on chemical pesticides by emphasizing preventive measures and natural pest control methods. This approach minimizes environmental impact while effectively managing garden pests. Rainwater Harvesting: Capture rainwater from rooftops and paved surfaces using rain barrels or underground cisterns. This harvested water can then be used for irrigation, reducing reliance on municipal water sources and lowering utility costs. Permeable Surfaces: Utilize permeable paving materials such as gravel, permeable concrete, or porous pavers for driveways, pathways, and patios. These surfaces allow rainwater to infiltrate the soil, reducing runoff and replenishing groundwater supplies. Mulching: Apply organic mulch, such as pine straw or wood chips, around plants to conserve soil moisture, suppress weeds, and improve soil structure. Mulching also helps regulate soil temperature, protecting plant roots from extreme heat or cold.
