How to Grow Agapanthus (African Lily) and Care
1. Ideal Place to Grow Agapanthus
• Sunlight: Full sun (6-8 hours daily). In warm climates, they prefer partial shade.
• Soil: Fertile, moist and well-drained. Note: Agapanthus africanus prefers acidic soils.
• Pots: Choose pots that are wider than deep, as the rhizomes need lateral space more than depth.
• Season: Spring, after frost, with soil temperatures ≥ 10 °C.
• Depth: Plant the rhizomes 5 cm deep and leave 30-45 cm between each one.
• Technique: Place the pointed ends upwards, cover with soil and water.
• Protection: In cold climates, add mulch around them to protect from the cold.
3. Aftercare
Watering
• During growth: Regular watering to maintain moisture.
• Established plants:
o Summer: 2-3 times per week.
o Winter: Once every two weeks.
Fertilization
• Fertilize in spring and two months later.
• Avoid high nitrogen fertilizers; use balanced formulas such as 10-10-10 or 5-5-5, or rich in phosphorus.
• Stop fertilizing in late summer.
Pruning
• Remove wilted flowers to encourage new shoots and avoid wasting energy on seeds.
• Leave the leaves after flowering so the bulb stores energy through photosynthesis.
4. Common Problems
• Lack of flowering:
o Excessive shade.
o Cold climate.
o Lack of protection during winter.
5. Winter Care
• In areas with temperatures above 0 °C: Rhizomes may remain in the soil.
• In cold areas:
o Dig up rhizomes before the first frost and pot them up indoors.
o Keep pots in a bright spot with temperatures of 12-15°C.
o Minimal watering: Keep the soil barely moist.
This schedule will help you care for and enjoy your agapanthus, ensuring they bloom year after year.
