New Lawn Seeding

According to many garden experts, it is always good to use fertilizer before planting grass seeds when you are growing for the first time.

As we have already mentioned, testing the soil pH level is important to know soil conditions.

You may have to use extra fertilizers if the garden soil has a poor condition. After all, it must have the right amount of phosphorus, potassium, and nitrogen.

Established, Cool-Season Grasses

When you live in a heavy cold area, you should choose cool-season grasses such as ryegrass, Kentucky bluegrass, tall fescue, etc.

These types of grass seeds are good enough to provide good quality food. When re-seeding the existing lawn, make sure to aerate the soil properly.

During the winter, grassroots may become weaker. That’s why you can use a high level of nitrogen fertilizer to strengthen their roots.

Make sure to apply the fertilizer in the early fall so that grass can develop strong roots before the winter season.

Established, Warm-Season Grasses

If you are living in a high-temperature zone, you should plant Warm-Season Grasses, such as centipede grass, Bermuda grass, Centipede grass, Bahiagrass, etc. They have higher toleration to heat withstand extensive heat.

For warm-season grasses, you can first apply fertilizer and then plant grass seeds. Do it during the spring season. This ensures optimal growth and will make the grass super greenish.

Grass Seed or Fertilizer First?

Grass Seed or Fertilizer First?

It requires a proper plan and preparation before planting grass seeds on a lawn. You can’t just randomly throw seeds on it.

You can use a broadcast fertilizer to spread both grass seeds and fertilizer at a time. However, there may be some situations in which it is not suitable.

And you must be careful while following this approach. Evenly mixing the fertilizer and grass seeds is necessary.

Otherwise, you won’t achieve a perfect result in all areas of the lawn. Consider planting grass seeds during the early fall. Plant accordingly based on it.

Since most grass seeds face a hard time during the winter season, you have to give the new grass enough to develop strong roots. Otherwise, frost may kill weak grasses.

Is It ok To Plant Grass Seed Immediately After Spreading Weed and Feed Fertilizer?

It is a good rule of thumb to avoid planting grass seeds immediately after using fertilizer. Since most weed and feed fertilizers have herbicides, they may stop or slow down the natural germination process of grass seeds.

You should only apply this type of fertilizer after the grass has become properly grown-up. Generally, you may have to wait until you mow the grass 3-to 4 times. It may take around 6-8 weeks before applying this type of fertilizer on your established lawn.

Can I Overseed After Fertilizing?

No, you can not be overseed after fertilizing. You should need to wait a minimum of one month before overseeding the new lawn. It is necessary to give the newly developed grass enough scope to collect water and nutrition from the soil.
