Can You Put Weed and Feed on New Grass Seed?
Starting a new lawn from seed can be a rewarding experience, but it also requires careful attention to ensure its healthy growth. One common question that arises is whether you can apply weed and feed products to newly sown grass seed.
The answer is: It's generally not recommended to use weed and feed on new grass seed.
Here's why:
Why Is Weed and Feed Not Recommended for New Grass Seed?
- Potential for Damage: Weed and feed products contain herbicides that are designed to kill weeds. While they can be beneficial in established lawns, applying them to new grass seed can damage the delicate seedlings and hinder their growth. The young roots are especially vulnerable to the herbicides, potentially leading to stunted growth or even death.
- Competition for Nutrients: Weed and feed products often contain fertilizers. While fertilizers can be beneficial for established lawns, they can also create competition for nutrients between the new grass seedlings and the weeds they are trying to control. This competition can further hinder the growth of the young grass.
- Unnecessary Stress: Newly established lawns are already under stress from the establishment process. Applying weed and feed products can add to this stress, potentially making them more vulnerable to disease and pests.
When Can You Apply Weed and Feed?
It's best to wait until your new grass has established itself before applying weed and feed products. Here are some general guidelines:
- Wait at least 6 weeks: Allow the grass to grow and root firmly before applying weed and feed. This will ensure that the grass is strong enough to withstand the effects of the herbicides and fertilizers.
- Mow Regularly: Before applying weed and feed, make sure you are mowing your lawn regularly, allowing the grass to reach a height of 2-3 inches.
- Water Deeply: Water your lawn deeply and thoroughly after applying weed and feed to help the herbicides and fertilizers penetrate the soil and reach the roots of the grass.
Alternatives to Weed and Feed for New Lawns
There are several alternatives to weed and feed that you can use to control weeds and fertilize your new lawn without causing damage.
- Pre-Emergent Herbicides: These herbicides can be applied before weeds germinate, preventing them from growing in the first place.
- Selective Herbicides: These herbicides target specific types of weeds without harming the grass.
- Organic Fertilizers: Organic fertilizers, such as compost, manure, and fish emulsion, provide nutrients to the soil without the risk of damaging your new grass.
Tips for Establishing a Healthy Lawn
Here are some additional tips for establishing a healthy lawn:
- Choose the Right Grass Seed: Select a grass seed mixture that is appropriate for your climate and soil type.
- Properly Prepare the Soil: Test your soil and amend it if necessary to provide the right nutrients and drainage.
- Sow Seed at the Right Depth: Don't sow the seed too deeply or too shallowly. Follow the instructions on the seed packet.
- Water Regularly: Water your new lawn regularly and deeply, especially during the establishment phase.
- Mow Regularly: Mow your lawn regularly at the correct height to encourage healthy growth.
Conclusion
While weed and feed products can be beneficial in established lawns, it's generally not recommended to use them on new grass seed. Applying weed and feed to new grass seed can damage the young seedlings and hinder their growth. Instead, focus on establishing a healthy lawn by using alternative weed control methods and organic fertilizers. By following these tips, you can help your new grass thrive and enjoy a lush, green lawn for years to come.
