Overwintering Dahlias: A Dartana Plants Guide

As autumn fades and winter approaches, your dahlias need a little extra care to ensure they bloom beautifully next year. Here’s how to protect these stunning tubers from frost and keep them healthy for the next growing season.

Why Overwinter Dahlias?

Dahlias are tender perennials, which means they can’t survive harsh winter conditions outdoors. Proper overwintering ensures:

• Healthy tubers for replanting in spring.
• Stronger growth and vibrant blooms next season.

Step-by-Step Guide

1. Lift the Tubers

• Wait until the first frost blackens the foliage.
• Cut back stems to about 15 cm (6 inches).
• Carefully dig around the plant and lift the tubers without damaging them.

2. Clean and Dry

• Shake off excess soil.
• Rinse gently if needed, then allow tubers to dry in a cool, airy spot for a few days.

3. Wrap and Store

• Wrap each tuber in newspaper or bubble wrap for insulation.
• Place them in a cardboard box or breathable container.
• Store in a frost-free location like a garage or shed (ideal temperature: 4–10°C).
