As an expert in lawn care, I strongly advise against putting straw over newly planted Bermuda grass seed. While some people may suggest using straw as a protective covering for the seed, it can actually do more harm than good in most cases.
One of the main reasons to avoid using straw is that it can create a barrier between the seed and the soil, hindering germination. Bermuda grass seed needs direct contact with the soil to absorb moisture and nutrients, and the straw can prevent this essential connection. Additionally, straw can also prevent sunlight from reaching the seed, which is another crucial factor for germination.
Furthermore, straw can create an ideal environment for weed growth. While it may seem counterintuitive, straw can contain weed seeds that will germinate and compete with your Bermuda grass seed for nutrients and space. This can lead to a weaker and less dense lawn in the long run.
If erosion is a concern in your area, it is better to use a weed-free mulch instead of straw. A mulch layer of less than 50 percent coverage can help protect the soil from erosion while still allowing sunlight and moisture to reach the seed. This way, you can strike a balance between erosion prevention and ensuring optimal conditions for Bermuda grass seed germination.
In my personal experience, I have seen cases where homeowners used straw over Bermuda grass seed, only to find that the seed did not germinate well and the lawn had patchy areas with minimal grass growth. On the other hand, when a mulch or erosion control mat was used instead, the results were much better, with a healthier and more even lawn.
To summarize, it is best to avoid using straw as a covering for Bermuda grass seed. Instead, opt for a weed-free mulch if erosion control is necessary. This will provide the right conditions for germination and help establish a healthy Bermuda grass lawn in the long run.
