It is important to choose the right time to apply weedkiller to achieve the best results.
Check the weather forecast
Choose a calm, dry day to apply your Roundup.
Don’t apply when it’s windy
Drift may damage plants that you don’t want to kill
Don’t apply when it’s raining.
If you have treated the weeds with Roundup Ready to Use products, and it rains within 30 minutes of application, repeat treatment may be necessary. If you have used Roundup Concentrate products, and it rains within 2 hours, repeat treatment may be necessary.
Don’t apply in very cold conditions
Don’t apply in very hot conditions
Don’t apply to drought-stressed plants or weeds
Ensure that you apply Roundup to the leaves
It is important to ensure that you spray the entire leaf, but try to avoid run off.
The best time to apply is when the leaves are green and growing, typically in the spring and summer.
