How to Keep Grass Seed from Washing Away?
If you’ve ever planted grass seed, you know that one of the biggest and most frustrating challenges is keeping it where you put it. Even with the best preparation, planting technique, and high-quality seed, there’s always a risk that the seed will be washed away by rain or simply blown away by the wind.
When you’re seeding a new lawn, it’s important to keep the seed from washing away. Grass seed can wash away on slopes, and in other areas where irrigation water runs off easily, such as hard-packed soil.
But there are ways to anchor your grass seed in place so it has a chance to germinate properly. Here are 10 tips for keeping your grass seed from washing away:
10 Ways To Stop Grass Seed From Washing Away
The first step in keeping your grass seed from washing away is preparing the soil. Loosen up the top layer of soil with a hand rake or tiller so that the roots have an easier time growing.
Make sure to work in fertilizer or manure before planting the grass seeds if you want them to grow well — if you fertilize too soon, birds might eat all of it before the seeds get planted! Next, plant your grass seeds using a spreader. Water them for about 30 minutes a few times per day until they start to sprout.
There are many ways to keep grass seed from washing away. Let’s take a look at some of them…
1. Sheet Mulch
The most effective or best way is to use a lightweight sheet mulch. The sheet mulch will hold the seeds in place and protect them from the elements. Also, it will help to hold moisture in the soil, so you do not have to water your newly planted seeds as often. This is the best way for you to get the grass seed down, and it does not wash away when it rains.
2. Control Blankets
To prevent seeds from washing away, you can use erosion control blankets or straw mulch. The blankets are made of biodegradable materials that will break down over time and feed the soil. Straw mulch is heavier than grass seed and stays in place better.
3. Protecting the Seed
The problem with grass seed is that it’s light and dry and can easily get washed away by rain or wind. One of the best ways to keep it in place is by covering it up with a bit of soil. You don’t need much—just enough to cover the seed with a thin layer of soil. Covering the seed with mulch or hay also works well.
4. Applying Compost
Another way to protect your grass seed from the elements is to apply a bit of compost. Not only does compost help trap moisture, but it also attracts beneficial microorganisms that aid in faster germination and better nutrient absorption.
5. Seed Treatment
Seed treatments are specially formulated for protection against wash-away and other common grass seeding problems. Seed treatments come in different forms—pellets, powders, sprays, etc.—and are designed for easy application on new and existing lawns.
One of the best ways to keep your grass seed from washing away is to use a product called Soil Moist. This substance is made from a natural polymer that absorbs water and then releases it slowly over time. It keeps your new grass hydrated even if it doesn’t rain for several days after planting.
6. Use a Soil Amendment
Amend soil with organic matter before planting grass. This increases water retention, which helps keep seeds from drying out and washing away. Mix a thin layer of peat moss into the top layer of soil with a rake or shovel. The addition of compost is another way to enrich the soil for planting grass.
7. Mulch Grass Seed
Covering seeds with mulch can help prevent them from washing away. Non-living mulches include plastic sheeting and straw or hay (as long as it hasn’t been treated with herbicide). Living mulches include plants that grow close to the ground, such as clover or alfalfa. Plant living mulches after seeding.
8. Use a Mechanical Aerator
Aerating your lawn pulls plugs of soil out of the ground, loosening soil and creating space for water, fertilizer, and nutrients to reach the roots. It’s also one of the best ways to reduce soil compaction and improve drainage.
9. Use a Power Rake
If your lawn is filled with thatch and dead grass, you’re going to want to use a power rake before seeding. Power raking exposes bare patches in your yard that’ll be ideal for new seeds while removing dead material that would otherwise compete with new seedlings.
10. Consider Using Grass Sod or Hydroseed
Grass sod or hydroseed could be an alternative offering better results than traditional seeding methods. Grass sod is a convenient option that can be installed without much hassle. Hydroseed is another convenient alternative offering similar benefits to sod at a lower price point.
In summary, you prepared the soil, chose the best grass seed for your lawn, and spread it at the proper rate. The next day, heavy rainfalls and all that hard work disappear down the drain. What happened to your grass seed?
Grass seed is small and light. If you don’t keep it in place, water or wind can easily wash or blow it away.
Prepare your soil before you plant your grass seeds. A well-prepared surface helps ensure that the seeds are planted at the optimal depth for good germination. It also gives them better traction in the soil so they don’t wash away as easily during watering or rain showers.
Rake thoroughly after planting your grass seeds. A thorough raking helps make sure that the seeds are covered with just enough soil so they stay put when you water them (but not so much that they have difficulty germinating). Raking also helps loosen up any clumps of dirt, creating a more even layer of soil over the seeds.
Use a starter fertilizer. Fertilizer provides nutrients that help new grass grow strong and healthy until it’s able to thrive on its own.
