September Landscape Checklist for Southwest Florida: 7 Things Your Property Needs After a Long, Wet Summer

By September, landscapes across Southwest Florida have been through months of heat, humidity, heavy rain and rapid summer growth. From residential properties in Naples and Bonita Springs to coastal landscapes on Sanibel and Captiva, this is an important time to evaluate what the rainy season has left behind and prepare the property for the months ahead.

For homeowners, HOAs, condominium communities, multifamily properties and commercial properties, September is a good time to look beyond routine mowing and identify issues with turf, plant material, irrigation, drainage and trees before they become larger problems.

Here are seven areas to check around your Southwest Florida landscape this September.

1. Evaluate Turf Health After the Rainy Season

Heavy summer rain and humidity can leave Southwest Florida lawns showing signs of stress, thinning, weeds, nutrient deficiencies or pest and disease activity.

Walk the property and look for areas that are yellowing, thinning, holding excessive moisture or simply aren’t performing like the surrounding turf. The appearance of the lawn can be a symptom of a larger issue, so identifying the cause is more important than simply treating what is visible.

For larger HOA, condominium and commercial properties, September is also a good opportunity to identify recurring problem areas throughout the community and develop a plan for correcting them.

2. Inspect Your Irrigation System

Just because Southwest Florida receives significant summer rainfall doesn’t mean the irrigation system should be ignored.

September is an excellent time for an irrigation wet check. Controllers, rain sensors, valves, sprinkler heads and individual zones should be inspected for proper operation and coverage.

Look for broken or misaligned heads, areas receiving too much or too little water, leaks and irrigation spraying onto sidewalks, buildings or roadways.

As seasonal rainfall patterns begin to change, irrigation schedules should also be adjusted accordingly. A system programmed for one part of the year may not be appropriate for the next.

3. Correct Overgrown Shrubs and Landscape Beds

Summer growing conditions can transform a well-defined landscape quickly.

By September, shrubs may be encroaching on walkways, windows, signage and other plant material. Beds can lose their definition, weeds can establish themselves and individual plants may begin competing for space.

The goal shouldn’t simply be to cut everything back. Proper selective pruning, bed detailing and plant management help restore the intended structure of the landscape while maintaining healthy plant material.

This is especially important around community entrances, residential front elevations, pool areas and commercial properties where the landscape contributes heavily to the property’s overall appearance.

4. Check Trees and Palms While Hurricane Season Is Still Active

September is still hurricane season in Southwest Florida, making tree and palm evaluation particularly important.

Property owners and managers should look for dead or compromised limbs, damaged branches, declining trees and other conditions that may warrant professional evaluation.

Palms should also be pruned correctly. Removing excessive green fronds or performing aggressive “hurricane cuts” can unnecessarily stress the palm.

For larger trees or questionable conditions, an evaluation by an ISA Certified Arborist can help determine whether corrective pruning or additional tree care is appropriate.

5. Look for Drainage and Standing-Water Problems

The rainy season has a way of revealing exactly where a property’s drainage problems are.

Pay attention to areas where water consistently collects after storms, landscape beds that remain saturated, erosion around downspouts or hardscapes and runoff flowing toward buildings, streets or neighboring properties.

Standing water and poor drainage can affect turf and plant health and may indicate that the landscape, grading, drainage or irrigation needs additional attention.

Waterfront and coastal properties in communities such as Sanibel and Captiva require particular attention to how landscape practices interact with surrounding waterways.

6. Inspect Plants for Pest, Disease and Nutritional Issues

Southwest Florida’s warm, humid environment supports beautiful tropical landscapes—but it can also create favorable conditions for insects, disease and other plant-health problems.

Inspect shrubs, ornamentals and turf for unusual discoloration, leaf damage, thinning, spotting or declining growth.

Rather than automatically treating every issue the same way, determine what is actually causing the problem. Responsible landscape management means treating identified problems appropriately instead of applying unnecessary products across the entire property.

September is also a useful time to identify nutritional deficiencies in palms and other landscape material and determine whether corrective treatment should be incorporated into the property’s ongoing plant-health program.

7. Start Planning Fall Landscape Enhancements

September is also the time to look ahead.

If summer exposed plants that aren’t performing well, outdated beds, bare areas or landscaping that has simply outgrown its space, begin planning improvements now.

That could include replacing declining plant material, redesigning an entrance, adding seasonal color, refreshing mulch or bed material, improving irrigation coverage or introducing plant material better suited to the property’s conditions.

Planning ahead allows improvements to be approached as part of an overall landscape strategy rather than as a series of emergency fixes.

A September Walk-Through Can Reveal a Lot

Southwest Florida landscapes change quickly. A property that looked great going into summer can have very different needs after months of rain, heat and aggressive growth.

Whether you’re maintaining a home in Naples or Bonita Springs, a coastal property on Sanibel or Captiva, or managing an HOA, condominium, multifamily community or commercial property, September is an excellent time for a comprehensive landscape assessment.
