Dahlia Deco Border Red are large, look-at me bright red flowers with a darker red centre. Dahlia ‘Deco Border Red’ combines well with perennials and other dahlia varieties. The flowers are real eye-catchers in the border. Dahlia tubers can be planted in the spring. Dahlia ‘Cambridge’ is sensitive to frost, so be careful with late night frost. Dig a spacious planting hole, loosen the soil and fill the planting hole with good potting soil. Carefully place the tubers in the planting hole and cover with 3-5 cm of soil. The planting distance of the tubers is 30-60 cm. Water the tubers immediately after planting. dahlias bloom most profusely in full sun. Store the tubers in a frost-free place after flowering and you will enjoy them for years to come.
