How to plant star dahlia tubers

Planting star dahlia tubers is straightforward, and with the right care, they’ll reward you with a stunning display throughout the summer. Follow these steps to ensure your dahlias thrive:

Choose the right location: Star dahlias love full sun, so pick a sunny spot in your garden that receives at least 6 hours of direct sunlight each day. They prefer well-drained soil to prevent tuber rot, so avoid areas that get waterlogged.

Prepare the soil: Before planting, dig the soil to loosen it and improve drainage. If your soil is heavy, mix in compost or grit to create a well-draining environment for the tubers.

Plant the tubers: Dig a hole about 10-15 cm (4-6 inches) deep. Place the tuber horizontally with the growing eye facing upwards. Cover the tuber with soil, ensuring it’s buried well but not too deep. Space the tubers about 30-45 cm (12-18 inches) apart to give each plant room to grow.

Water carefully: After planting, water the area thoroughly to help the soil settle. Once the plants start growing, water regularly, but avoid overwatering as dahlias don’t like sitting in soggy soil.

Support if necessary: As star dahlias can grow tall, you may want to add a stake or support when planting to prevent the stems from bending or breaking as they grow.

By following these simple steps, your star dahlias will thrive, providing a vibrant display of their unique star-shaped blooms from mid-summer through to autumn.
