It's best to wait a few weeks after fertilizing before seeding, to allow the fertilizer to fully penetrate the soil and avoid the risk of burning the new grass. ' 1. This starter feed is suitable for spring or fall application and will help to establish new grass seed and encourage strong root systems.
Your best bet is to fertilize your newly seeded or overseeded lawn with Scotts® Turf Builder® Starter® Food for New Grass directly after seeding. Then, you need to wait 6 to 8 weeks before fertilizing again.
The best time to apply fertilizer to your vegetable garden is before planting each growing season. This allows the nutrients in the fertilizer to be readily available to the young plants as they grow.
Fertilizing Your New Grass
Apply starter fertilizer only once you've lightly raked your soil and before you sow your grass seed. Once your grass has seeded, the next round should be a regular fertilizer application – this round should only occur four to eight weeks after the first, starter application.
Seed in the spring or summer. Fertilize in late spring or early summer and late summer or early fall.
Answer: Yes, you can apply a winterizer fertilizer such as Scotts Turf Builder WinterGuard Fall Lawn Food at or around the same time as overseeding since there is no herbicide. This formulation is designed for established turf, but the boost of nutrients would only help the new seeding.
Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, 6 to 8 weeks after the summer feeding.
Fertilizing in the fall helps plants be hardier when the temperatures drop. We also recommend applying fertilizer in the late fall, toward the end of October or early November. This application will catalyze one last frenzy of root growth and really give your plants some staying power through the cold months.
A complete fertilizer with a high ratio of both nitrogen and potassium is essential for enhanced rooting, cold hardiness, disease resistance, and wear tolerance. An ideal fall fertilizer blend has a nitrogen to phosphorus to potassium (N:P:K) ratio of 24-4-12 with isobutylidene diurea (IBDU).
We recommend waiting 24 hours after fertilizing to water your lawn, which will give the fertilizer time to settle. After the 24 hours are up, it's important to give it a good soak—not just a quick spritz with your hose—to activate the fertilizer and help the critical nutrients absorb into the soil.
You should fertilize your lawn a day or so after a light rain or using a sprinkler. This prevents the application from being washed away. The moisture gets your soil damp and ready to receive nutrients. Do not apply fertilizer before or after heavy rains.
If done too early you could be inviting damage from the winter weather, such as snow mold. The best time to fertilize can depend on the climate, but typically September and October are usually the best months to apply fall fertilizer.
Fertilize your lawn in early fall and again 6 to 8 weeks later with Scotts® Turf Builder® WinterGuard® Fall Weed & Feed. Not only will it help build strong, deep grass roots for a thicker, better lawn come spring, but it also provides nutrients to help repair damage from summer heat, drought, and activity.
Can I put too much fertilizer on my lawn? There is the idea of “too much of a good thing,” and that definitely applies when it comes to fertilizing your lawn! Applying too much fertilizer to your lawn will cause the nitrogen and salt levels in the soil to increase rapidly, which can damage or even kill the grass.
Use a slow-release nitrogen fertilizer, such as Milorganite, when overseeding. Mixing Milorganite with the seed not only makes nutrients available to the grass when it needs it, it also makes it easier to see where the tiny seeds have been broadcast. This counts as the fall fertilization.
If fast results are desired, lightly water the product in after application; however, watering-in is not required.
Treat weeds and feed your lawn with Scotts® Turf Builder® WinterGuard® Fall Weed & Feed3 in the fall for a better lawn next spring. This weed killer plus lawn fertilizer controls over 50 listed lawn weeds, including clover, dandelion, plantain, morningglory, chicory, eveningprimrose, and purslane.
While this fall lawn fertilizer dose is important, an application at the end of October or early November is essential. At that time, apply a fertilizer with a formula of 13-25-12. The push of phosphorus will stimulate root growth through November and even into early December.
“Once spring arrives, your lawn will quickly tap into these nutrients for a beautiful burst of green. In fact, a lawn fed twice in the fall will stay green longer into winter and be the first to green up in the spring.”
Don't fertilize during a drought.
Most fertilizers need a thorough watering or two to soak into the soil, and allowing the fertilizer to sit on top of the lawn without watering it in could burn the grass. You may want to delay the application until wet weather arrives.
Early morning is the best time of day to fertilize your lawn. Fresh morning dew provides just enough moisture for your grass to absorb the fertilizer.
In fact, it's good! Water helps fertilizer fully absorb into the soil. Mild rain after you fertilize is nothing to worry about. But a downpour, or several days of consistent rain, can be a problem.
Nitrogen, phosphorus, and potassium take time to absorb into your soil. Doing anything too drastic on your lawn, such as cutting your grass, will disrupt this process. We always suggest to our clients that they wait 24 to 48 hours before mowing their lawn after fertilization.
Rain After Fertilizer -- Granular Applications
Granular fertilizer and insecticide applications need to be watered in. This activates the product. Slow-release granular fertilizer is not easily washed away and doesn't dissolve quickly in water. So rain after fertilizer is actually a good thing.
For warm-season grasses, any temperature below 65-75°F, depending on grass variety, is too cold to apply fertilizer and give it a chance to fortify your lawn before it goes dormant. For cool-season grasses, you'll want to apply winter fertilizer a couple of weeks before temperatures consistently fall below 60°F.
