After spraying your lawn with a broadleaf weed control, you should wait to mow for 24 to 48 hours.
Why Wait to Mow After Spraying?
Waiting is crucial to allow the herbicide to work effectively on the weeds. Based on expert recommendations:
- Herbicide Translocation: Broadleaf weed control products need time to move from where they landed on the leaf surface throughout the plant's vascular system. This process, known as translocation, takes at least 24 hours.
- Effectiveness: If you mow too soon (before the 24-48 hour window), you risk cutting off the leaves where the herbicide was absorbed before it has fully translocated down into the roots and other parts of the plant.
- Full Absorption: Allowing the full 24 to 48 hours ensures the herbicide has enough time to be absorbed and distributed within the weed, leading to a more effective kill.
Cutting the grass prematurely essentially removes the treatment before it can complete its job within the weed, potentially requiring reapplication or resulting in poor weed control.
Key Takeaway:
| Action | Recommended Waiting Time After Spraying |
|---|---|
| Mowing the lawn | 24 to 48 hours |
By following this guideline, you maximize the effectiveness of the broadleaf weed control and promote a healthier, weed-free lawn.
