How to Apply Lawn Seed & Fertilizer Together


Establishing or overseeding a lawn and laying down an application of fertilizer are two steps that can easily be combined to save both time and effort. Use a walking drop spreader with the appropriate measurements of seed and lawn starter fertilizer for the acreage to be covered mixed in the hopper and applied over the prepared soil. The key is to use a gentler lawn starter fertilizer to prevent any burn to the grass seed and shoots as they com up through the soil. After watering you'll have a seeded and fed lawn ready to sprout green shoots in a few days to a few weeks.

Step 1

Calculate the amount of grass seed for your acreage and the recommended disbursal setting for the hopper by consulting the label on your grass seed bag.

Step 2

Determine the amount of lawn starter fertilizer needed by using the square footage of the area to be seeded and consulting the package label.

Step 3

Mix half of the amount of grass seed and half the amount of lawn starter fertilizer in the drop spreader hopper and use a dowel or stick to mix evenly.

Step 4

Walk the perimeter of the area with the drop spreader engaged and then walk the interior of the prepared soil area in neat, slightly overlapping rows.

Step 5

Water in the fertilizer and seed with a hose sprayer attachment set on mist or light rain. Soak the soil slowly without disturbing the seed and fertilizer or making divots in the soil. Keep the soil evenly moist with daily or twice daily watering through the germination phase.
