At Addenbrooke we have our ‘Dahlia Farm’ which has flourished over the last two years, yielding an amazing crop of cut flowers. From this we have been able to recognize the beauty of all the Dahlia varieties and wonder at the beauty and magic of nature.
All these Dahlia tubers from Aorangi we have selected are varieties we also grow here at Addenbrooke or will be growing; they are all stunning!
Dahlias are very easy to grow and provide a rewarding display with very little effort. Plant the tubers with the main growing tips just below the surface of the soil. Firm the soil around the tubers, being careful not to damage them.
Prepare your garden beds well. Dahlias prefer well-drained, acidic loam but will grow relatively well in any soil as long as it isn’t too wet. Dig down approximately 20-30cm and amend the soil by adding compost to increase the porosity and nutrient density as dahlias are heavy feeders. Lay the tuber sprout-side up 7-8cm deep in a trench and cover it over with the prepared soil. Dahlias need to be kept weed-free. Mulch around the plants to prevent weeds and conserve moisture. Pinch back the terminal bud or the primary growing tip when the plant is about 40cm tall to enforce good branching and structure and increase budding. Provide plenty of water to your plants. Water plants deeply once or twice per week. Big dahlias will need a support structure such as mesh which is what we use or corral them in with twine to keep the heavy blooms from bending to the ground.
Fertilize monthly with water-soluble fertilizer - we use Seasol a few times during the growing season.
