Scotts Step 3 should be applied in the summer, specifically between June and August. It is recommended to apply it approximately 4 to 6 weeks after Step 2. Step 3 is designed to feed and strengthen the lawn against heat and drought and helps the lawn hold onto moisture and stay green during the hot summer months. It can be applied to any grass type. Additionally, it's advised not to apply Step 3 in temperatures over the high 80s or in dry conditions to avoid stressing the lawn. If rain is not expected after application, watering the lawn immediately afterward will help activate the treatment and reduce stress on the grass. Mowing can resume about two days after applying Step 3. In summary:
- Apply Step 3 between June and August.
- Wait 4 to 6 weeks after applying Step 2.
- Avoid applying if temperatures exceed the high 80s or during dry conditions.
- Water immediately after application if no rain is expected.
- Mow about 2 days after application.
This timing applies across various sources and aligns with the Scotts 4-Step Lawn Care program recommendations.
