You should
wait at least 2 weeks after applying 2,4-D before planting grass seed.
Here's why:
* 2,4-D is a herbicide: It kills broadleaf weeds by disrupting their growth processes.
* Grass seed needs a healthy environment: If 2,4-D residue is still present in the soil, it can harm the delicate young grass seedlings, inhibiting their growth and potentially killing them.
Here are some additional considerations:
* Soil temperature: Ensure the soil temperature is suitable for germination before planting.
* Type of 2,4-D: Some formulations of 2,4-D might break down faster than others. Check the product label for specific instructions.
* Other herbicides: If you used other herbicides in combination with 2,4-D, follow the longest recommended waiting period.
It's always best to err on the side of caution and wait longer than necessary. This will give the 2,4-D ample time to break down and ensure the best chance of successful grass seed germination.
