Product Overview
Jonathan Green Top Dress™ Seedling Cover and Growth Accelerator is a 100% recycled paper mulch. It covers and protects new grass seedlings, prevents washouts and erosion of the seedbed, and conceals the seed from birds. Good seed-to-soil contact and consistent moisture are required to get new turfgrass seedlings off to a proper start. Jonathan Green Top-Dress™ helps hold newly planted grass seed in place while keeping the seedbed moist. Top-Dress replaces the need for straw mulch, eliminating messy cleanup. Top-Dress contains starter fertilizer (1-0-0) to promote deep rooting.

Once the new grass plants are rooted, the mulch biodegrades and disappears into the soil so there is no need for removal. Mow the new lawn when the turfgrass grows three inches tall. Germination time depends on the seed mixture planted.

Don’t Forget These Essentials

  • 100% recycled paper (cellulose fiber), corn fiber, green dye, and grass seed starter fertilizer (1% controlled release nitrogen)

  • 1-0-0

  • Spread Top Dress™ Seedling Cover & Growth Accelerator after applying grass seed to the prepared area.

     

    For cool-season lawns, the best time to apply grass seed is in fall (between mid-August to mid-October), or in spring (between mid-March to mid-May). For grass seed to germinate, soil temperatures must be at least 55°F. Best root growth occurs between 55° and 70°. If soil temperatures are at or above 75°, seedling root establishment will not occur.
  • Yes, the mulch degrades into the soil once the new grass plants are rooted.

  • Place it in a cool dry place, off of the ground, out of direct sunlight, and keep it away from moisture. Keep bags (especially that have already been opened) containing unused product in a locked storage area inaccessible to children and pets. Do not store near feed or foodstuffs.

     

    To prevent cross-contamination, do not store near open containers of fertilizer, seed or other pesticides. Under these conditions, fertilizer will last at least two years.

  • Always read and follow the product label before use.

How to Apply

Seed

Spread grass seed over the planting area. Refer to the back of the grass seed bag for how to apply.

Apply

Protect

Wear gloves to spread Top Dress™ by hand or use a lawn spreader set to the largest opening.

Rake

Rake the Top Dress™ mulch evenly over the seeded area. Some soil and grass seed should be visible through the mulch.

Apply

Apply Top Dress™ only on lawns and gardens and sweep any product that lands on the sidewalk or driveway back onto the lawn.

Maintain

Water

Water the area after applying seed and Top Dress™ but do not overwater. Keep the top 1 inch of soil moist by watering daily for the first 14 days or until new grass growth appears. Then reduce watering to twice a week. Top Dress™ mulch will absorb the water and expand to cover the grass seed. Do not remove Top Dress™, it will biodegrade naturally.

Mow

Mow the new grass once it is 3 inches tall. Never scalp the grass by removing more than half the grass blade while mowing. This stresses the grass which results in thinning and bare spots.
