Planting Tips for Summer Annuals in Zone 9
To maximize the beauty and longevity of your summer annuals, follow these planting tips:

- Prepare the soil: Ensure well-draining soil enriched with organic matter for optimal growth.
- Water wisely: Regular watering is essential, especially during heatwaves, but avoid overwatering to prevent root rot.
