Kid and pet safe:

Since kids and pets will roam on the grassy lawn, you must pick a safe mulch. And if you use something not suitable for pets and kids, make sure they stay away from the mulch or don’t consume it.

Is mulch good for grass seed?

Grass seeds need proper moisture and temperature for germination. When you keep them uncovered, these grass seeds may dry off and fail to sprout due to the lack of humidity. Thus, mulch helps them to maintain the necessary humidity level and temperature for proper germination.

Many formulas, these days, contain both mulch and fertilizer at the same time. These mulches lock the moisture and feed the grass seedlings with the essential nutrient for an even green lawn. For the best result, you need to spread the mulch in an even layer without putting too much on the spot to help the grass seeds grow and sprout better.

Will grass seed grow in leaf mulch?

Yes, grass seed will grow in leaf mulch. At first glance, it won’t look pretty. But within a couple of days, the leafy mulch will perish in the grass blades and offer a natural mulch for the grass seeds to cover it and preserve the required moisture and temperature.

What’s more, mulched leaves are an effective method to battle the lawn weeds that soak the nutrient to dry up the grass seeds. Nonetheless, use a lawnmower and mulching blade to cut the leaves into smaller ones to transform them into a natural mulching resource. It will cover the grass seed to boosts its sprout.

Should you put straw over grass seed?

The mulched straw for grass seed will reduce the evaporation rate of water from the seeded ground. It will, thus, help to preserve the required moisture level in the grass seed. You should leave the straw mulch over the grass until the seeds sprout. Once they grow big enough for mowing, they won’t need any extra mulch covering anymore.

Besides, the straw will prevent the grass seeds from getting washed away during rainy days due to heavy rainfall. Therefore, mulch straw doubles its benefit as a moisture retainer and keeps the seeds from running away with rain.

How much straw to put on new grass?

Although covering grass seeds with straw is an excellent way to retain moisture in the ground, putting too much straw on new grass can be harmful. It shouldn’t cover more than ¼” depth of the growing grass seeds. Thus, you have to spread the straw lightly over the seeds.

Taking this into count, you will roughly need 1-bale of straw to cover 1000 square feet of seeded lawn for light coverage. One bale of straw is available from $40 t0 $75 mostly. So, you need to invest it to over the new grass with straw safely.
