  1. Early Growth Stage: Spray weed killer when weeds are in their early growth stage. They are more susceptible to the herbicides (weed killer) at this stage.

  2. Ideal Weather: Ideally you want a calm day NO wind, and NO RAIN, (if it rains the herbicide (weed killer) won't work!

  3. Temperature Range: Spray in cool weather if you want to get techinical about it 60°F - to about 80°F would be ideal for optimal absorption for the herbicide. This isn't a big deal.

  4. Weed Growth Stage: Usually you can get pre-emergence (weeds in soil) and post-emergence (weeds you can see) herbicides. So when you have thick weeds get a post-emergence herbicide, if you need help look up a herbicide dealer. (not cannabis!)

  5. READ INSTRUCTIONS: Always read and follow the instructions on the weed killer product label for proper timing and application guidelines and saftey! keep away from children!
