Grower Tips

Planting: In USDA zones 8–10, plant tubers in fall for early spring blooms. In colder zones (3–7), fall planting is only recommended with frost protection—otherwise, store tubers in a cool, dry place and plant in late winter or early spring. Soak tubers in room-temperature water for 1 to 3 hours before planting. Plant claw-side down, 2 to 3 inches deep.
Spacing: Space 4 to 6 inches apart. For dense displays, aim for 50–75 tubers per square meter.
Light: Full sun is essential—at least 6 hours daily. Choose a sheltered spot with good air circulation.
Soil: Fertile, well-drained soil with a pH of 6.0–7.0. Amend with compost or leaf mold to improve structure.
Watering: Water after planting and keep soil lightly moist during active growth. Avoid soggy conditions—ranunculus tubers are prone to rot.
Temperature & Protection: Hardy to about 25°F (–4°C). In zones 8–10, mulch after planting to buffer against cold snaps. In zones 7 and below, use frost cloths or grow in containers that can be moved indoors.
Fertilization: Feed every 2–3 weeks with a high-potash fertilizer once growth begins. Liquid seaweed is a great organic option.
Pruning: Deadhead regularly to encourage more blooms. After flowering, allow foliage to die back naturally.
Pest & Disease: Watch for aphids, slugs, and powdery mildew. Good airflow and hand-picking pests help prevent issues.
