Dahlia Striped Vulkan

Dahlia Striped Vulkan is a speckled cactus dahlia, bursting with summer colours, it flowers all through the season, from July to October.

Plant 10 – 15cm deep to give the tuber a good foundation. Dahlia Striped Vulkan will reach a mature height of around 100cm and a spread of up to 50cm.

Plant dahlia tubers in pots from mid spring and place into a frost free warm and sunny environment such as a cold frame, green house or window ledge to get an early start. However, they can be planted straight into the ground from April once the frosts have passed. When planting, make sure dahlia tubers have adequate drainage, plant with the eyes (buds) facing upwards. Place in soil rich in organic matter such as compost or aged manure at a depth of around six inches. Water lightly and consistently so the soil remains moist but not soggy. Be mindful to remove any dead flower heads regularly to encourage re-blooming. Fertilize every other week with a high quality fertilizer to ensure strong growth.

Dahlias are not frost hardy and will need to be lifted again in November. The young leaves are vulnerable to slugs but as the plant gets older they tend to leave them alone.
