In short
- A fertilizer near a seawall calculator checks four of the City of Cape Coral's published rules together: stay 15 ft back from the top of the wall, nothing from June 1 to September 30, nothing during storm alerts, and at least 50% slow-release nitrogen.
- Any failed rule means no. The tool names the first one that applies, so you know what to change.
- May can be added to the ban by the City Manager, so May shows as a call-the-city result.
- A lawn 25 ft back in July fails the summer ban; the same lawn in November passes.
On this page
This fertilizer near a seawall calculator is for Cape Coral canal owners and lawn crews who want a quick yes or no before anything is spread. It turns the rules in our landscaping near a seawall guide into a check, and uses no prices. It is general information, not legal advice.

Example: 25 ft from the wall top, July, 60% slow-release. Illustrative numbers, not a recommendation.
How the check works
- Storm alerts come first.
The city page bars fertilizing during a Flood, Tropical Storm or Hurricane Watch or Warning, wherever the lawn is.
- Then the strip.
No fertilizing within 15 feet of the top of a seawall or any water body. The page allows hand dispersion only where no material reaches the water.
- Then the calendar.
No nitrogen or phosphorus fertilizer June 1 to September 30. The City Manager may extend the ban to include May.
- Then the product.
Fertilizer must contain at least 50% slow-release nitrogen. Leave the box blank if you have not checked the bag.
What each result means

Questions to ask your lawn service
- How do you keep fertilizer 15 ft back from the wall? Get the method in writing.

- What is the slow-release percentage? Ask for the product label.
- Where do clippings go? They must not end up in the water or storm drains.
Next step: wall work, not just the lawn
This tool checks fertilizer rules, not the wall. We are a referral service, not a contractor; we connect visitors with independent local providers. If the soil behind your wall dips or washes out, use the form below to ask independent local contractors for a written quote, and read how to choose a seawall contractor first.

Frequently asked questions
Can I fertilize my lawn next to a Cape Coral seawall?
The City of Cape Coral's fertilizer ordinance page says no fertilizing within 15 feet of the top of a seawall or any water body, with hand dispersion allowed so that no material reaches the water. Farther back, the summer ban, storm alerts and product rules still apply. This tool checks them together; read the city page for the current version.
When is fertilizer banned in Cape Coral?
The city page lists a ban on nitrogen and phosphorus fertilizer from June 1 through September 30, and says the City Manager may extend it to include May. It also bars fertilizing during a Flood, Tropical Storm or Hurricane Watch or Warning.
What counts as a slow-release fertilizer?
The city page says fertilizer must contain at least 50% slow-release nitrogen. The percentage is on the bag's guaranteed analysis or product label; if it is not listed, ask the seller or choose another product.
Where do I measure the 15 feet from?
The city measures from the top of the seawall, not from the water. If your wall has a cap, measure from the cap edge toward the house and round down when unsure.
Does my lawn service have to follow this too?
Ask them in writing how they keep fertilizer back from the strip and where clippings go. Our landscaping guide has questions to put to a lawn crew.
