Garden departments such as ours, and most garden centers in our area have been promoting “Winterizer” for lawns through the Fall months. Many customers ask, “What is a lawn winterizer? Is it important for my lawn?” A lawn winterizer is a type of fertilizer blend that generally has a moderate amount of nitrogen, little to no phosphorus, and is relatively high in potassium. This would mean that the N-P-K (the numbers) on the front of the winterizer bag might look like, 12-0-15, or something similar.
A lawn winterizer is made to give the lawn a nice green color without stimulating growth. Most importantly, this fertilizer promotes healthy root development and builds disease resistance in the grass. Many people in the green industry consider the lawn winterizer to be the most important lawn fertilization of the year. A lawn receiving this fertilizer will be denser, greener, healthier, and able to withstand harsh winter weather with little damage. Lawns without this treatment will not manage winter conditions nearly as well.
Winterizer can be applied in conjunction with your annual fall lime treatment on the lawn. Applying each treatment the same day is generally not a problem. Lawn winterizer and pelletized lime can be applied from October through mid-December, as long as the grass is not frozen (frosty).
Stop in and pick a bag or two of our Winterizer lawn fertilizer if you haven’t applied this important treatment yet. We carry the Fertilome and Bonide brands of premium lawn Winterizer. Pelleted lime is still available too should you need it. Your lawn will thank you for the winterizer by looking green, dense, and healthy coming out of winter dormancy next spring!
