The ‘Forrestal’ Cactus Dahlia is a semi-cactus variety known for its brilliant, bright red, oblong petals . It produces large blooms (around 15 cm) on sturdy stems that reach up to 100 cm high, making it an excellent statement flower for summer landscapes and cut floral arrangements. [1, 2]
Key Growing Requirements:
- Planting: Dahlias grow from tubers. Plant in a sunny, well-draining spot after the last frost.
- Depth & Spacing: Place tubers 5 cm to 10 cm deep with the “eyes” pointing upwards, spaced approximately 45 cm apart.
- Sunlight: They require full sun to thrive but can tolerate light shade during the intense midday heat.
- Water & Feeding: Keep the soil moist but not waterlogged. Fertilize monthly during the summer growing season. [1, 2, 3, 4]
