How long after putting weed and feed on lawn can you seed?

You should wait at least 4-6 weeks after applying weed and feed to your lawn before seeding.

Here's why:

* Weed and feed contains herbicides: These chemicals can harm or kill newly germinated grass seeds.

* Time for the herbicide to break down: It takes time for the herbicide to break down in the soil and lose its effectiveness.

* Soil conditions: Weed and feed can sometimes alter the soil's pH and nutrient levels, making it less ideal for new seed germination.

Important:

* Read the label: Always check the specific instructions on your weed and feed product. Some products may have different waiting periods.

* Test the soil: If you're unsure, you can test the soil for herbicide residue before seeding.

It's best to err on the side of caution and wait the full 6 weeks to ensure the best chance of successful seed germination.
