Grass plugs are individual turf plants grown in trays. They are small clumps of grass that can be used to repair damaged areas of lawns, fill in patches of bare soil, trial a new grass type, or even start a new lawn. Grass plugs are relatively inexpensive and easy to plant, and they grow quickly enough that you won’t have to wait long before they look good in your lawn. Here are some benefits of using grass plugs:

  • Grass plugs establish faster and require less water than seed.
  • Plugs are a more affordable option compared to sod, making them a cost-effective choice.
  • Cobalt St. Augustine Grass Plugs are easy to establish and easy to maintain.
  • They provide a natural solution for repairing a damaged lawn, particularly in small areas.
  • You can use plugs for fun and creative DIY projects.
  • They are effective for repairing or filling in damaged spots.
  • You can test different grass varieties before committing to a full sod order.

Our 72-count plug trays can cover up to 72 square feet when spaced 6–18 inches apart on center. For quicker ground cover, plant each plug closer together. Each plug is 1.25 inches long x 1.25 inches wide x 2 inches tall.”

To install grass plugs, follow these steps:

  1. Collect a soil sample and make any required soil amendments to create a conducive environment for plugs to grow.
  2. Prepare the soil by removing any weeds or debris. Mow existing lawn close to the ground. Rake the soil smooth and level.
  3. Water the soil thoroughly.
  4. Dig up or use an auger bit to drill holes for the plugs, spacing each hole 6–18 inches apart.
  5. Fertilize the holes before planting the grass plugs with a fertilizer that has a lot of phosphorus like Lawnifi Grow, the first bottle of the New Lawn Starter Box. Use Soil Moist Granules to reduce plant stress and watering.
  6. Press the plugs into the soil firmly, and use additional soil to fill the holes, ensuring the plugs are securely positioned and upright in the ground. The grass blades should be level with the ground.
  7. Keep the soil moist 6–8 inches deep every day until the plugs are established for the first 10–20 days after installation. This may require 2–4 waterings per day. Once new runners start to appear, decrease watering to twice a week.
  8. Ensure firm root establishment before mowing; gently tug a section to check. Mow only when the grass is dry to avoid soil compression and root issues. Set your mower at the highest level initially to prevent a vacuum effect; lower it gradually for future mowings.

Review update

Updating my previous review:
It’s now January 19,2024. My plugs have survived the drought and extreme heat of 2023. Now after days of below freezing temps as low as 16 degrees I’m checking on my sample plug areas of my lawn. It’s nothing short of dramatic!! The following photos are from the most exposed part of my lawn. Look at the difference in the grass blades of the Cobalt plug grass blades vs. my existing St Augustine. The Cobalt grass blades are still green and full vs. the other St. Augustine that shows considerable freeze damage. Zoom in on the center of the photos and then pan around the edges and you will realize the dramatic differances. Congratulations to Texas A&M and Sod Solutions for bringing this new hybrid variety of St Augustine to the market!

Great grass plugs

I'm about to place my fifth order for plugs, after parts of my yard were heavily damaged by fungus and this summer's drought. Of the almost three hundred plugs received, only two plugs were not viable. I've had a 100% success rate in my sunny front and back yards, with the plugs thriving and spreading. I've had about a 30% success rate in the heavily shaded yard between our house and a neighbor's (I think because I use too much fertilizer, as replacement plugs are doing much better).

Too early to tell but looks promising

Plugs arrived quickly in good condition. Since we are in the middle of a drought I divided my sheet of plugs into only four sections to create a larger area of sod, planting them in four quadrants of my yard as a test. They are already establishing and starting to send out runners. I will watch the test areas thru the fall, winter and early spring. If the Colbalt preforms as promised I plan to plug more of my yard in the spring Keeping my fingers crossed. It already appears to be taking on a richer green color and seems to be more compact and more dense than St. Augustine variety that I currently have. It does seem to be more corse to the touch. I’ll back off of the watering in a few weeks and see how it does. Many of my neighbors are watching the progress and hoping for good results.

Cobalt St. Augustine

Awesome packing! It showed up with very little yellowing and looked like artificial turf it was so green. Looking forward to seeing it take off and fill in my dead spots where I planted.
