Flawless Lawns in South Florida: A Seasonal Guide
Awakening and Preparation
Spring (March – May) Spring is the transition season—the ideal time to prep the ground before the sweltering summer heat arrives.
Mowing Height Adjustment: Start slightly lowering your blade height to remove the excess thatch accumulated over winter. This allows sunlight to reach new shoots. Think of it as a mechanical "deep clean" that helps the plant breathe.
Strategic Fertilization: Apply a slow-release fertilizer once the grass is actively green. In Broward County, we must be careful with local nitrogen regulations to protect our groundwater and aquifers.
Weed Control: This is the time to apply pre-emergent herbicides before weed seeds germinate in the rising heat.
Survival and Moisture Control
Summer (June – August) Summer in Central and South Florida means daily rains and record-breaking temperatures. The goal here is disease control and managing accelerated growth.
Mowing Frequency: The grass grows at an incredible rate. We recommend mowing every 7 days to avoid removing more than one-third of the grass blade at a time, which stresses the plant. By cutting less than 33%, the plant barely notices and continues to grow normally.
Fungus Watch: Excessive overnight moisture can trigger fungi (such as Brown Patch). Ensure your automatic irrigation does not activate if there has already been sufficient rainfall.
Sharp Blades: Wet grass is harder to cut. Keeping your equipment blades sharp is vital to prevent tearing, which invites pests.
Recovery and Strengthening
Autumn (September – November) As the rains taper off and nights turn (slightly) cooler, the lawn needs to recover nutrients lost during the summer washout.
Core Aeration: This is an excellent time to aerate the soil, allowing oxygen, water, and nutrients to reach roots compacted by summer rains.
Reduced Irrigation: Begin spacing out your watering days. The lawn does not need as much water as it did in July, and excessive autumn moisture is a leading cause of insect infestations, such as sod webworms.
Palm Pruning: Take the opportunity to clear out spent or brown fronds before the high-wind season ends.
Preventive Maintenance
Winter (December – February) While we don’t experience extreme freezes in Deerfield Beach, the lawn enters a phase of slow growth (partial dormancy).
Higher Mowing Height: Raise your mower deck. Taller grass provides better insulation for the root system against overnight temperature fluctuations.
Watering on Demand: Only water if you notice signs of stress (grass blades curling or turning a bluish-gray tint). In winter, less is more.
Equipment Maintenance: This is the ideal window to service your mowers and irrigation systems, leaving them ready for the cycle that begins in March.
Consistency: The Secret to Success
In our family business, we always say the best fertilizer is the "owner’s shadow"—or the watchful eye of a professional. A Florida lawn isn't cared for "once a year"; it thrives on small weekly adjustments dictated by the thermometer and the clouds.
