Buying dahlias at Garden Select: the ideal choice for colour in the garden and a perfect Christmas gift

Dahlias are popular summer bloomers that add colour to any garden for months. Garden Select offers decorative dahlias and large-flowered varieties that bloom from July to October. Dahlia tubers are planted in spring, but the best time to buy them is around Christmas. In December, the full range is in stock, and a dahlia tuber makes a unique Christmas gift for any garden enthusiast.

Buying, overwintering and safely storing dahlia tubers for the new season

Dahlia tubers are available from late December and can be stored cool and dry until March. This is the period when many customers plan their gardens, making the purchase of dahlia tubers during the holidays ideal. During overwintering, it is important that the tuber remains frost-free, as dahlias are sensitive to low temperatures. Spent flowers and buds from the previous season are removed so the plant can save energy for the next growth period. Slugs can sometimes cause damage in spring, so check young shoots as soon as the dahlias begin to sprout.

The tubers are planted from early March. The soil must be loose and rich so the tubers can root well. After planting, new buds quickly appear and later develop into large flowers in summer. Once July arrives, the flowering period begins and continues until the first frost.

Planting and caring for dahlias from March until flowering in July

Dahlia tubers are placed in a shallow planting hole and covered with three to five centimetres of soil. The planting hole should be spacious so the tubers can spread well. A planting distance of thirty to sixty centimetres gives each plant enough room. During growth, spent flowers are removed regularly to stimulate new buds and prolong flowering. This makes the dahlia one of the most rewarding border plants.

Dahlias thrive in full sun and create striking colour accents in summer. They are also excellent as cut flowers and last long in a vase. A tuber can be reused for many years when it is dug up in winter and stored frost-free.
