If you live in southern areas where lawns feature warm-season grasses, fertilize turf in late spring or early summer, just before grass kicks into high gear. Make a second application in late summer. If your warm-season lawn goes dormant in winter, don't fertilize after the first of September.
Your soil test will determine which fertilizer is best for you. Bring your soil as close to neutral as possible to get the most benefit from the fertilizer you use. A pH range between 6.0 and 7.0 is accepted as being the best for growing quality grass.
Besides, if you fertilize in fall, the lawn doesn't need another application until later in the spring, anyway. Even though cool-season grasses stay green, avoid fertilizing during the heat of midsummer. Growth naturally slows down in very hot weather, and applying fertilizer at that time can actually weaken the lawn.
If your lawn's soil pH is too low or too high, the fertilizer you use may not work very well. Soils with a low pH, like 5.5 or 6.0, will require applications of lime to "sweeten" the soil. Soil pH values above 7.5 will require soil sulfur or a fertilizer containing sulfur to bring the pH down.
Knowing when to fertilize your lawn can be challenging. The natural growth cycle of the lawn dictates the best time to fertilize.
Before fertilizing,try to make sure your lawn does not have an excess buildup of thatch that can suspend the fertilizer in the grass leaves and inhibiting it from reaching the soil. Suspended fertilizer can also burn the grass leafs.
The best time to fertilize your lawn is in the spring, when the soil temperature reaches 55 degrees Fahrenheit. You'll know when the soil warms up to 55 because the lilacs begin to blossom and the grass starts growing. For most parts of the country, that means the first feeding should take place by about mid-April.
How to Fertilize Properly: Adjust the setting on the spreader. Pour in half the bag of fertilizer and walk back and forth over your entire lawn.
Fertilizing your lawn can help you get the lush, green grass you desire. To properly fertilize your lawn it's important to prepare the ground, pick out the right fertilizer, and use a method that will give your lawn the best chance to grow in stronger and healthier.
Fertilize your lawn as soon as the dormant grass is at least 50 percent green again. Use quick-release weed and feed fertilizer to eliminate unsightly weeds without harming your grass. Avoid using weed and feed if you plan to reseed your lawn in the same season.
