Cactus dahlias such as Dahlia Black Touch are spiky (hence the name) and provide ideal colour for any garden. An easy to grow group of plants that provide an abundance of colour through out the summer.
Dahlias are best started off indoors from January to March as they are sensitive to frosts. Plant in a mix of multi-purpose compost, sand and grit as this will provide drainage for the tuber. Protect young shoots from snails and slugs and when the fear of frosts has passed the tuber can be re-planted outside or the container positioned outdoors.
Plant outside from Late March on wards, when the signs of frost have passed the dahlia tuber can be planted outside. Plant tubers into well prepared soils in late March to April. Cultivate to a depth of 20cms to allow good root development. Plant tubers in fertile soils with 5cms of soil above the top of the tuber. Protect early growth from slugs and snails and remove dead heads during the flowering season to get the best from them. Regularly feed during the growing season with foods such as are well rotted manures, tomato feed and bone meal for continued flowering.
