Rainy season lawn care Fort Lauderdale homeowners need is different from the rest of the year, so this guide covers what to adjust from late spring through fall.
Summer in Fort Lauderdale means heat, humidity, and almost-daily afternoon storms. From roughly late May through October, your lawn gets more rain than at any other time of year, and it grows fast. That sounds like a good thing, but too much water and heat can also bring soggy spots, fungus, pests, and stressed grass.
The good news: a few simple habits make a big difference. Here’s how to care for your lawn during the South Florida rainy season.
Know Your Grass Type
Most Fort Lauderdale lawns are St. Augustinegrass, but you’ll also see zoysia, Bahia, and some bermudagrass. Each one handles heat, shade, and water a little differently, so the first step is knowing what you have.
- St. Augustine: Wide, flat blades. Handles heat and some shade well, but is prone to chinch bugs and certain fungal problems.
- Zoysia: Fine to medium blades, dense feel. Likes a lower, more frequent mow.
- Bahia: Tough and drought-tolerant, often seen on larger or lower-maintenance properties.
If you’re not sure, a local lawn care pro can identify it quickly.
Mow Higher, Not Lower
In the summer it’s tempting to cut short so you mow less often. In South Florida, that usually backfires. Taller grass shades its own roots and soil, holds moisture better, and crowds out weeds.
General height guidelines many Florida lawn experts recommend:
- Standard St. Augustine: about 3.5 to 4 inches
- Dwarf St. Augustine varieties: about 2 to 2.5 inches
- Zoysia: about 1 to 2.5 inches, depending on variety
- Bahia: about 3 to 4 inches
A few more mowing tips for the rainy season:
- Follow the one-third rule. Don’t remove more than one-third of the blade at a time. During peak growth that may mean mowing weekly.
- Keep blades sharp. Dull blades tear the grass, leaving ragged tips that brown and invite disease.
- Avoid mowing soaking-wet grass when you can. It clumps, ruts soft soil, and can spread fungal spores.
Rainy Season Lawn Care Fort Lauderdale: Rethink Your Watering Schedule
One of the most common summer mistakes is running the sprinklers on autopilot while it’s raining every afternoon. Overwatering leads to shallow roots, fungus, and wasted water.
Tips for smarter summer irrigation
- Let the rain do the work. If you’ve had a good soaking, skip the scheduled cycle.
- Check your rain sensor. Florida law requires automatic irrigation systems to have a working rain sensor or similar shutoff device. Make sure yours isn’t broken, disconnected, or blocked by plants.
- Water early in the morning when watering is needed, so blades dry during the day.
- Follow local watering rules. Fort Lauderdale and Broward County follow South Florida Water Management District restrictions on which days and times you can irrigate. Check current rules for your address.
Watch Your Drainage
Heavy downpours show you exactly where your yard holds water. Standing water that lingers for more than a day can suffocate grass roots and lead to thin, yellow, or rotting patches.
Things to look for after a storm:
- Puddles that don’t drain within 24 hours
- Downspouts dumping water straight onto the lawn or against the foundation
- Low spots, compacted soil, or areas where water flows toward the house
Small fixes like downspout extensions, regrading low spots, or adding plant beds that handle wet soil can help. For bigger problems, a landscaper can look at your drainage options.
Be Aware of Fungus and Pests
Warm, wet weather creates good conditions for some lawn problems. You don’t need to be an expert, but knowing the early signs helps you act before damage spreads.
Common warning signs
- Fungal problems: Spots or lesions on blades, circular brown or yellow patches, or grass that looks water-soaked. Overwatering, too much nitrogen fertilizer, and mowing wet grass can all make fungus more likely.
- Chinch bugs (St. Augustine): Yellowing or brown patches that often start in sunny, hot areas near driveways or sidewalks, and don’t green up after rain.
- Grubs and other insects: Grass that pulls up easily like a loose carpet, or more birds than usual pecking at the lawn.
Different problems call for different treatments, so it’s worth getting a proper diagnosis before you apply any product. Treating the wrong issue wastes money and can stress the lawn further.
Be Careful With Summer Fertilizer
Many South Florida communities limit fertilizer use during the rainy season. Heavy rain can wash nitrogen and phosphorus into canals and waterways. Before you fertilize in summer, check the current rules for your city and county, and always follow label directions. Slow-release products and careful timing are generally better for both your lawn and local water quality.
Prep Your Yard for Hurricane Season
Hurricane season runs from June 1 through November 30, overlapping with the rainy season. A little lawn and landscape prep goes a long way:
- Keep trees and palms trimmed, and remove dead or weak branches before storms are in the forecast. Our tree trimming service can help.
- Store or secure loose items like planters, furniture, and decorations.
- Keep storm drains and swales near your property clear of clippings and debris.
- After a storm, clear debris off the lawn quickly so the grass underneath doesn’t die off.
When to Call a Pro
If you have patches that won’t recover, recurring drainage issues, or just don’t have time to mow weekly through the summer, professional help can keep your yard on track. And if a section of lawn is too far gone, sod installation may be the fastest way to restore it.
