Product Overview
The Jonathan Green Grass Seed & Fertilizer Bundle for Alkaline Soil is perfect for seeding lawns with alkaline soil. It combines an all-natural soil amendment, quick-germinating grass seed, and nutrient-enriched starter fertilizer to help you grow the lawn of your dreams.

This lawn care bundle includes Mag-I-Cal® Plus for Lawns in Alkaline & Hard Soil, which loosens hard & compacted soils and lowers high soil pH all in one, convenient product. When soil is compacted, air, water, and nutrients cannot travel down to the lawn’s root system. This can prevent new grass seedlings from germinating and growing properly. Mag-I-Cal® Plus breaks up hard soils and releases any essential nutrients that may have been trapped within the soil by adjusting the pH.

The Grass Seed & Fertilizer Bundle for Alkaline Soil also includes our most popular grass seed mixture, Black Beauty® Ultra, great for quickly filling bare spots in thinning lawns and fast-establishment for newly seeded lawns. It contains an expert mixture of three turfgrass varieties: tall fescues, Kentucky bluegrass, and perennial ryegrass. Black Beauty® Ultra Grass Seed grows naturally dark green turf with a waxy protective coating on the leaf, similar to the skin of an apple. With quick germination in just 7 - 14 days, you’ll grow grass that boasts a gorgeous green hue, withstands the elements, and lasts for years to come!

In addition to our quick-germinating grass seed, we include Veri-Green Starter Lawn Fertilizer for Seeding and Sodding to give new grass seedlings a boost of nutrition for successful germination. It contains a phosphorus-rich formula to help new grass seedlings develop deep, dense roots, which helps your lawn endure harsh cold winters and long, hot summers. Use Veri-Green Starter Lawn Fertilizer for Seeding and Sodding the same day you seed to jumpstart grass development.

How to Apply

Prepare

Mow

To ensure the seed reaches the soil, mow the lawn on the lowest setting and bag the clippings.

Rake

Use a metal rake to remove debris, rocks, and thatch that has built up. Rake vigorously to create grooves in the top layer of soil. Fill in any holes and level the ground with additional topsoil if necessary.

Apply

Set

To evenly distribute lawn care products, use a spreader suitable for your specific lawn size. Set the spreader according to the recommended setting on the packaging or use our Spreader Settings Tool above. Make sure to update the setting with each product you apply.

Amend

Optimal soil pH for cool-season lawns is 6.2 to 7.0. Fill your spreader with Mag-I-Cal® Plus. Start by spreading the product around the lawn’s perimeter to establish a turning area. Then, make back-and-forth passes within the outlined area, ensuring overlap for complete coverage. Sweep any excess granules off of hard surfaces and back onto the lawn.

Seed

Carefully read and follow all instructions on the product labels prior to application. Before spreading, calculate the amount of seed needed for the square footage of your lawn.

  • For new lawns:
    Start by filling the spreader with half of the grass seed. Apply the seed around the perimeter of the lawn to establish a turning area. Make straight passes back and forth across the length of the lawn in one direction (north to south) and then the remaining seed in a perpendicular direction (east to west) within the outlined area. Overlap slightly between passes and close the hopper when turning. Walk at a steady pace for even distribution. ​​This crisscross pattern ensures even coverage and helps prevent bare spots in new lawns.
  • For overseeding:
    Begin by spreading the seed along the perimeter of your lawn. Make straight passes back and forth across the length of the lawn in a mowing pattern until the entire area is covered. Overlap slightly between passes and close the hopper when turning. Walk at a steady pace for even distribution.
Rake

After seeding, gently rake the soil with a metal rake to incorporate the grass seed into the top quarter-inch of soil. This will improve seed-to-soil contact and promote germination.

Fertilize

Maximize seedling growth and root development by applying starter fertilizer along with the seed. Fill your spreader on a hard surface to avoid fertilizer burn. Start by applying fertilizer around the lawn’s perimeter to establish a turning area. Then, make back-and-forth passes within the outlined area, ensuring overlap for complete coverage. Sweep any excess granules off of hard surfaces and back onto the lawn.

Water

Immediately after applying, thoroughly water the area but not to the point of run-off or puddles.

Maintain

Water

Keep the soil consistently moist by watering lightly several times a day, or as needed, to prevent drying out. Avoid excessive watering that may cause pooling or runoff. Continue watering daily for a few weeks until the grass plants reach a height of 2 – 2.5 inches. As the grass seed germinates, gradually reduce the frequency of watering while increasing the amount applied to encourage deeper root growth.

Mow

Begin mowing when the new grass has reached a height of 3 – 4 inches. Make sure the mower has sharp blades. Be careful not to scalp the lawn, low mowing will stress the root system and encourage the growth of weeds.
