Conventional
A measured mineral product. It can green a lawn faster. It is also easier to over-apply. The bag rate is the ceiling, not a starting suggestion.

Organic vs. conventional fertilizer for Marion County yards
Organic and conventional are two ways to feed a lawn or a bed. Neither one is a reason to use more than the yard needs. In unincorporated Marion County, keep nitrogen and phosphorus off saturated soil and away from water.
Key takeaways
- Conventional products release nutrients on a shorter schedule. Organic products break down more slowly.
- More is not greener. Extra granules wash off sandy soil and burn the grass.
- In unincorporated Marion County, do not apply nitrogen or phosphorus before seeding or sodding, or in the first 30 days after, and do not apply it on saturated soil.
- This is general information, not a reading of your lot. City of Ocala rules can differ from the county code.
Marion County sand does not hold nutrients the way clay does. A heavy hand shows up twice: a burned lawn, and green water where the extra ran off. The useful choice is the product you will apply at the low rate, on dry ground, and sweep off the walk.
How to tell them apart
Organic
Meals, composted products, and other materials that soil life has to break down. The color comes slower. You can still overdo it, and you still keep it out of the street.
Use this when
| Situation | Conventional | Organic |
|---|---|---|
| A kept lawn on a maintenance route | Yes, at the lowest rate the yard needs, watered in, and not on saturated soil. | Yes, if you want a slower feed, at the lowest rate the yard needs. |
| The soil is soaked after a storm | No. Wait until it drains. | No. The county code says not to apply nitrogen or phosphorus on saturated soil. |
| Before seeding or sodding, or in the first 30 days after | No nitrogen or phosphorus in unincorporated Marion County. | Same rule. The limit is the nutrient, not the brand. |
| Within about 30 feet of a pond, stream, lake, canal, or wetland, or inside the larger setback near a spring or sinkhole | Stay out of the fertilizer-free zone. Ask before you spread. | The setback is about nutrients reaching the water, not about the brand. |
Unincorporated Marion County's land development rules, including fertilizer timing and setbacks from water, are in the county code. Lots inside Ocala should check the city. We do not treat this page as your permit.
What goes wrong if you swap them
Using a conventional rate on an organic bag, or the reverse
The bags are not interchangeable. Read the one in your hand. Sweep granules off concrete back into the grass, not into the drain.
Feeding a tree that needs pruning or removal
Fertilizer does not fix a split trunk or a dead limb over the roof. That is tree work.
What to tell the crew
- Turf type if you know it, and whether you want fertilizer on the lawn, the beds, or both.
- Ponds, sinks, wells, and ditches on the property.
- Whether the sod is new.
- Organic or conventional, if you have a preference. If you do not, say so.
Where this stops
Fertilizer treatment is an add-on to landscape maintenance, not a soil test by itself. Mulch still matters in sand. See when to replace mulch. A kept lawn that gets this treatment is finish mowing, not a field cut.
Add fertilizer to a maintenance visit
Weed treatment and fertilizer treatment can be added to a regular route. Tell us the grass and whether the yard touches a pond, a sink, or a ditch.
