The Best Fertilizer for Grass- Lawn Fertilizer Buying Guide
Fertilizer is important for your lawn. Your lawn will receive many nutrients it needs from the soil, but your lawn needs extra nutrients to be healthy. In addition, fertilizing helps your grass gain color, recover from the stress of foot traffic, and prevent weeds and diseases. The staff at The Earthworm has tested a variety of different products, and picked the four best fertilizers.
What Season Should You Fertilize?
For cool-season grasses like Bluegrass, Fescue, and Ryegrass, it is recommended that at the very least you fertilize once in the spring and once in the fall. An application during May with a high rate of nitrogen will give your lawn the jump-start it needs to become green and lush. An application of fertilizer with a high rate of nitrogen and potassium in the fall will prepare your lawn for winter, and help it recover faster in following spring. For warm-season grasses like Bermuda, Buffalo, and Zoysia, a late spring application several months before the first frost is beneficial.
What Time of Day Should You Fertilize?
If you are fertilizing with a fertilizer that has a high percentage of nitrogen, the time of day that you fertilize does matter. If you fertilize when there is a heavy dew on the ground, the fertilizer could stick to the grass blades instead of making their way down to the soil. When granular fertilize sticks to the grass blades it could burn up the leaves of the grass and cause dead spots. Before you fertilize, make sure your lawn is dry as possible.
What Does N-P-K mean?
N stands for Nitrogen. Nitrogen is found in most fertilizers, and usually gives the most results of any other nutrient. Nitrogen helps plants grow faster and more efficiently. Nitrogen also help develop leaves and helps lawns “green up.”
It is important to note, that over-applying nitrogen to your lawn can be problematic. Excess nitrogen can cause burn marks in your grass so it is important to calibrate your spreader, and spread the fertilizer evenly across your lawn.
When you see a fertilizer N-P-K ratio that is 25-0-4 it means that it contains 25% Nitrogen, 0% Phosphorus, and 4% Potassium. You may be confused when you see that the nutrients only make up 29% (25% + 4%) of the fertilizer. The rest of the fertilizer is primarily “filler material” that will be of no benefit to the lawn. Sometimes fertilizer contain Iron which is an essential nutrient for grass. If there is a low amount of iron in the soil, grass will have trouble growing and maintaining a vibrant green color.
