- Plant in the evening: If you are planting on a hot day, do it in the late afternoon or evening. This gives plants overnight to recover from transplant shock.
- Choose healthy plants: Look for plants with strong stems and green leaves. Avoid plants that are root-bound or wilted. Check for pests before buying.
- Prepare the soil: Loosen the soil to a depth of 8 to 10 inches. Mix in compost or aged manure. This improves drainage and fertility.
- Watch for frost: The first frost in Connecticut usually occurs in late September or October. Check your local frost dates. Choose flowers that will bloom before then.

Common Mistakes To Avoid
Even experienced gardeners make mistakes. Here are some common ones to avoid when planting in August.
- Planting too late: Some flowers need time to bloom before frost. Check the days to maturity on seed packets. Choose fast-growing varieties.
- Overwatering: While new plants need water, too much can cause root rot. Check the soil moisture before watering. Let the top inch dry out between waterings.
- Skipping soil prep: Poor soil leads to poor plants. Always amend your soil with compost. Test the pH if you are unsure. Most flowers prefer neutral to slightly acidic soil.
- Ignoring sunlight needs: Some flowers need full sun, others need shade. Read the plant tags. Place them in the right spot from the start.
- Forgetting to harden off: If you buy transplants from a greenhouse, they need to adjust to outdoor conditions. Gradually expose them to sun and wind over a week.
Benefits Of August Planting
Planting in August has several advantages. The warm soil encourages fast root growth. The days are still long, giving plants plenty of light. Many flowers bloom quickly, providing late-season color. Perennials have time to establish before winter. You can also take advantage of end-of-summer sales at garden centers. Plus, you get to enjoy your garden during the pleasant late summer weather.
Another benefit is that many pests are less active in late summer. Slugs and snails are less of a problem. Weeds also slow down. This means less maintenance for you. The cooler nights help plants recover from the heat of the day. Overall, August is a rewarding time to garden in Connecticut.
