              How To Choose The Best Fertilizer For Kentucky Bluegrass?

              Choosing the best fertilizer for Kentucky bluegrass depends on several factors. You need to consider the soil conditions, climate, and lawn care activities.

              Test Your Soil’s pH

              Kentucky bluegrass prefers a soil pH of 6.0-7.0, so it is important to test your soil’s pH before applying any fertilizer.

              If your soil has a higher pH, you may need to use an acidic fertilizer or lime to bring the pH down before fertilizing.

              Consider The Climate In Your Area

              Climate is also another important factor.

              In general, cool-season grasses like Kentucky bluegrass require more nitrogen in the spring and fall to grow, while warm-season grasses require more nitrogen in the summer.

              Type Of Lawn Care Activities

              What’s the type of lawn care activities you are performing?

              If you are overseeding in the fall, then you should use a fertilizer that’s low in phosphorus and high in nitrogen. A big plus if it also contains a pre-emergence weed control. This will give the new grass seedlings a boost of nutrients and help prevent weeds from taking over. To make sure you have a healthy lawn, consider some weed and feed for fall overseeding.

              On the other hand, if you are only mowing and performing general maintenance, then a balanced fertilizer like 10-10-10 can be used.

              Remember to always test your soil's pH before applying any fertilizer, and adjust the ratios according to the weather and time of year.
