A stunning selection of Cactus Dahlias - all mixed up in the same bag.
Cactus Dahlia’s are well valued for their large spiky florets. Flowering up to 120 cm tall they 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.
Some taller varieties may need staking and an occasional spray with a fungicide is beneficial to control powdery mildew. To prolong the flowering, pluck off old flowers. This encourages further flowering. Cut back spent foliage to ground level each Autumn.
