If you didn’t fertilize last fall, take a deep breath, and relax. Resist the urge to double up in the spring. Adding more than the recommended amount in spring is not only wasteful but can also damage your lawn. Instead, spread 32-0-4 grass fertilizer after the first mowing, then again four to six weeks later. The numbers stand for 32% of Nitrogen, 0% Phosphorus and 4% Potassium.
Organic lawn food, such as corn-gluten meal or a mix of feather, bone and blood meals, works more slowly than synthetic fertilizers, so the lawn will take an extra week to green up.
Lastly, mark your calendar or set a reminder on your phone to feed this coming fall.
