Over-Seeding Existing Lawns

Mar 22nd, 2023


Keep your lawn density up! *By over-seeding your existing lawn.

One proven way to get your lawn density back into shape is by over-seeding your lawn with matching JB Signature Premium lawn seed

Over-seeding helps thicken your lawn and helps keep weeds from taking hold.

This is especially important in the spring and the fall and will help keep your lawn healthy year-around.

When to seed: 

Cool season grasses germinate and grow best when the soil temperatures are between 50 and 65 degrees F. These temperatures usually occur when the daytime air temperatures are between 60 and 75 degrees.


Preparation: Mow your lawn as short as possible before seeding. You want the best ‘seed to soil’ contact that you can get. 

Carefully rake out all loose vegetation to expose the soil as needed. 

Apply- JB Signature Starter Fertilizer*Avoid using a weed & feed fertilizer when over-seeding your lawn.

Over-seeding: Using a spreader, spread seed evenly over the prepared area at the rate of 4-5 lbs. per 1000 sq. feet 

*Use JB TurfMend in thin areas and/or bare spots in the lawn for better results. 

Water: It is important to keep a seeded area moist at all times, as the seed establishes, without over-watering.

Fertilize: Use a JB Signature Starter Fertilizer in establishing the over-seeded area. Once well rooted and established- fertilize with JB Signature Maintenance Fertilizer in your normal pattern, typically 3 to 5 times per year depending on site and lawn type.

Keep it green, dense and healthy and enjoy your beautiful JB lawn this year!
