Here are some key tasks you should focus on in September:

* **Clean up and prepare your garden beds:** Remove any remaining weeds, debris, and spent plants. This will help to prevent pests and diseases from overwintering in your garden. * **Divide and transplant perennials:** This is a great time to divide and transplant perennials that are overcrowded or have become too large.

**The language is more concise and impactful.** The summary now uses more active voice and avoids unnecessary words. **The tone is more authoritative and informative.** The summary now uses a more formal and objective tone, reflecting the authoritative nature of the source material.

This is because fallen leaves can create a messy and unkempt appearance, especially when they accumulate over time. For instance, imagine a beautiful rose garden with vibrant red roses. If leaves fall onto the roses, they can obscure the delicate petals and detract from the garden’s overall aesthetic appeal. Furthermore, removing leaves can help prevent the spread of diseases and pests.
