The Dahlia Cactus “Cheerio” is a tuberous perennial known for its striking, deep pink cactus-style blooms that reach up to 15cm across. Thriving in full sun and well-draining soil, it grows up to 1m tall and flowers heavily from mid-summer through autumn. [1, 2, 3, 4, 5]
Planting & Care
- Planting: Plant tubers 8cm deep and 15–40cm apart. Ensure the “eye” or central stem points upward.
- Watering & Feeding: Water deeply every 3–4 days (about 10 minutes) and feed every two weeks with a high-quality bulb fertilizer to promote larger blooms.
- Pruning: Pinch back young shoots to encourage bushy growth and remove side buds to get larger flowers. [1, 2, 3, 4]
Winter Dormancy
Dahlias are not frost-hardy. After the blooming season, cut stems back to 5cm, carefully lift the tubers from the soil, and store them in a dry, cool, frost-free place over winter until it is time to replant in the spring.
