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]
