Starting a new lawn or patching up bare spots can be a rewarding project, but it requires careful planning and execution. One crucial factor to consider is the potential impact of lawn care products on newly sown grass seed. Will Scotts Weed & Feed harm your delicate seedlings?
Understanding Scotts Weed & Feed
Scotts Weed & Feed is a popular product designed to control weeds and fertilize your lawn simultaneously. It typically contains a combination of herbicides and fertilizer, offering a convenient solution for lawn maintenance. However, the presence of herbicides raises concerns about their potential to damage newly germinated grass seed.
The Risks to Grass Seed
Many herbicides, including some found in Scotts Weed & Feed, can be harmful to young grass seedlings. These chemicals can interfere with the germination process, stunt growth, or even kill the seedlings altogether. The risk is particularly high when applying the product too soon after seeding.
## Will Scotts Weed & Feed Kill Grass Seed?
It’s a common concern for homeowners: you’ve just sown new grass seed, eager to see a lush, green lawn, and now you’re wondering if applying Scotts Weed & Feed will sabotage your efforts.
The short answer is: it depends.
Scotts Weed & Feed products contain both fertilizer and herbicides. While the fertilizer is beneficial for your new grass, the herbicides can be harmful to young grass seedlings.
Understanding Scotts Weed & Feed
Scotts Weed & Feed products are designed to control weeds while simultaneously fertilizing your lawn. They typically contain:
* **Herbicides:** These chemicals target specific weeds, preventing their growth.
* **Fertilizer:** This provides essential nutrients to help your existing grass thrive.
The type and concentration of herbicides vary depending on the specific Scotts Weed & Feed product. Some products are formulated to be safer for newly seeded lawns, while others are more potent and should be avoided.
The Risks of Using Weed & Feed on New Seed
Applying weed & feed to freshly seeded lawns poses several risks:
* **Seedling Damage:** Herbicides can damage or kill young grass seedlings, preventing them from establishing roots and growing.
* **Uneven Growth:** If some seeds survive while others are killed, you may end up with an uneven lawn with patches of bare soil.
* **Delayed Germination:** Herbicides can interfere with the germination process, delaying the emergence of your new grass.
When It’s Safe to Use Weed & Feed on New Seed
Some Scotts Weed & Feed products are labeled as safe for use on newly seeded lawns. These products typically contain:
* **Pre-emergent Herbicides:** These herbicides prevent weed seeds from germinating, protecting your new seedlings.
* **Slow-Release Fertilizer:** This type of fertilizer releases nutrients gradually, minimizing the risk of burning young grass.
Always carefully read the product label before applying any Scotts Weed & Feed product to your lawn.
Alternatives to Weed & Feed for New Seed
If you’re concerned about using herbicides on your new grass, consider these alternatives:
* **Hand-Weeding:** This is the most environmentally friendly option, but it can be time-consuming.
* **Organic Weed Control:** There are several organic herbicides available that are less harmful to grass seedlings.
* **Pre-Emergent Herbicides:** Apply a pre-emergent herbicide before seeding to prevent weed seeds from germinating.
By understanding the risks and benefits of using Scotts Weed & Feed on new seed, you can make an informed decision that will help your lawn thrive.
In conclusion, using Scotts Turf Builder Weed & Feed on newly sown grass seed is generally not recommended. We discussed the potential harm that the fertilizer and herbicides in these products can have on delicate seedlings. The high nitrogen content can cause rapid top growth, potentially overwhelming the developing root system, while the herbicides can directly kill the young grass plants.
It’s crucial to allow grass seed to establish a strong root system before applying any weed and feed products. Waiting until the grass is at least 3 inches tall and well-rooted minimizes the risk of damage. For new lawns, consider using a starter fertilizer specifically designed for seed germination and early growth. This will provide the necessary nutrients without harming the developing seedlings. Remember, patience is key when establishing a new lawn.
Frequently Asked Questions about Scotts Weed & Feed and Grass Seed
Will Scotts Weed & Feed kill newly sown grass seed?
Yes, Scotts Weed & Feed can potentially kill newly sown grass seed. The product contains herbicides that are designed to kill existing weeds, but these same chemicals can also harm young, delicate grass seedlings. It’s crucial to wait until your grass seed has germinated and established itself before applying any weed & feed products.
How long should I wait to apply Scotts Weed & Feed after seeding?
It’s generally recommended to wait at least 6-8 weeks after seeding before applying Scotts Weed & Feed. This gives the grass seed ample time to germinate, establish roots, and develop enough to withstand the herbicides in the product.
Are there any Scotts Weed & Feed products safe for newly seeded lawns?
Scotts does offer some Weed & Feed products specifically formulated for use on new lawns. Look for products labeled as “new lawn” or “starter fertilizer.” These products typically contain lower concentrations of herbicides and are designed to be gentler on young grass.
Can I spot treat weeds in a new lawn without harming the grass seed?
Spot treating weeds in a new lawn can be risky. It’s best to avoid using any herbicides, even spot treatments, until your grass is well-established. Consider using manual methods like hand-pulling or using a hoe to remove weeds from your new lawn.
What’s the best way to prevent weeds in a new lawn?
Preventing weeds in a new lawn starts with proper preparation. Ensure your soil is free of existing weeds before seeding. Use a pre-emergent herbicide before seeding to prevent weed seeds from germinating. Finally, maintain a healthy, dense lawn by watering regularly, fertilizing appropriately, and mowing at the correct height.
