Dahlias
Part 2: Dividing
We have now finished planting the last of our dahlias, but it's not too late to demonstrate how to divide a large tuberous root by splitting it to create more plants. The tuber has been stored over winter and our first task is to examine it for any signs of rot, slugs and mice damage. Once the affected parts are removed, we have to decide on the best way of splitting the root and separating its potato-like individual tubers.
Sometimes a large root presents clearly visible division points; it's then possible to divide the tubers by easing them gently apart. In other cases we would use a sharp knife, making sure that each of the newly separated tubers is showing shooting points, called 'eyes'.
OUR ADVICE:
- Store dahlia tubers in dry, cool and well-ventilated places.
- Make sure that each of the newly separated tubers has 'eyes'.

The Land Gardeners
Award-winning garden designers and cut flower growers on a mission to save our soil.
Garden designers, flower growers and compost creators, Henrietta Courtauld and Bridget Elworthy joined forces to found The Land Gardeners in 2012. United by their passion for organically grown plants and a shared interest in soil health, they began by growing and selling cut flowers to esteemed florists, and worked on restoring historic gardens to their former glory. Most recently, they launched Climate Compost - a project born from years of inquisitive research into soil biology with the aim of creating a microbially rich compost that produces nutrient dense crops, while also supporting and boosting the local ecosystem. With an unwavering commitment to improving the health of our land and its biodiversity, The Land Gardeners’ approach is one of sensitivity, unparalleled expertise and, above all, a loving respect for the natural world and its preservation.
