How do you grow Dahlia Yams?
Posted by Suttons Staff on 16 July 2013 12:45 pm
Dahlia seeds are sown from February to April in a propagator on a windowsill or in the greenhouse at a temperature of 15-20º C (60-68ºF) covering the seed with5mm (¼″) of compost. Once the seedlings are large enough to handle transfer them into 9cm (3½″) pots.

Once the danger of frost has passed plant out in a sunny position spacing them 35cm (14″) apart. Keep the plants well watered in dry spells and feed the plants regularly with a balanced liquid fertilizer. To get the very best tubers the flower buds should be removed as they appear, to direct the plants energies into root production.

The dahlia tubers are ready to harvest when the foliage has been blackened by a slight frost. Cut of the top growth leaving only about 10cm (4") of stem attached to the tubers and carefully fork them out of the ground. They should be lifted before any severe frost has occurred.The tubers can be stored , in boxes covered with just damp compost, in a dry frost free shed or greenhouse.
