Kentucky bluegrass is one of the most beautiful grass varieties and is used in many upscale commercial properties. Kentucky bluegrass' thick, lush look and feel add elegance to any lawn. One challenge with Kentucky bluegrass is properly fertilizing it throughout the year. While many other grasses only need fertilization once or twice a year, Kentucky bluegrass performs best when fertilized three times a year. To achieve a healthy Kentucky bluegrass lawn, use the right kind of fertilizer in adequate proportions.
Things You'll Need
- Fertilizer spreader
Choose a Kentucky bluegrass fertilizer that is high in nitrogen. Nitrogen is the first number on a bag of fertilizer, with phosphorous being the second number and potassium the third.
Spread 5 pounds of fertilizer over 1,000 square feet of new Kentucky bluegrass (established for one year or less) with a hand or push spreader. Spread 1 to 2 pounds of fertilizer over 1,000 square feet of Kentucky bluegrass that has been established for more than one year.
Lightly water the fertilizer into the Kentucky bluegrass with a sprinkler. This helps the fertilizer soak into the soil and allows it to penetrate the roots of the grass.
Keep people and pets off the Kentucky bluegrass for at least 24 hours after fertilization. This allows the fertilizer to properly dissolve into the roots.
Tips & Warnings
- Fertilize Kentucky bluegrass at least three times a year, with the first application being in September, the second in November and the third in May.
- Cover any bare spots in the Kentucky bluegrass with straw after applying the fertilizer to prevent it from washing away.
- Do not fertilize on a very windy day or if a heavy rain is expected within 24 hours.
- Make only one pass over your Kentucky bluegrass lawn with each fertilization. Too much fertilizer can burn the grass.
- Keep the fertilizer out of your flower beds, as it can promote the growth of grass and weeds.
- Wear gloves and protective glasses or goggles when applying fertilizer to prevent it from getting on your hands and face.
