How and When to Plant Ranunculus
Plant ranunculus corms in Zones 8–11 in October or November so that they bloom during the following spring in warm states. In Zone 7 and colder, plant pre-sprouted ranunculus corms in early spring, a week or two before the last frost date. In either case, plant the corms 2 inches deep in well-draining soil. Expect the ranunculus to stop blooming when temperatures reach 80°F.
Ranunculus corms can be purchased at local garden centers or online. When and how you plant the flowers depends on where you are located. These flowers do not enjoy intense heat and are better planted in cool areas. The plants bloom approximately 90 days after the corms are planted.
Prepare indoor container-grown ranunculus in the fall. Soak the corms for four to six hours before planting them in a pot. Use loam-based compost with 20 percent horticultural grit and a slow-release fertilizer added to help with drainage and plant health. Space the soaked corms with claws facing downward about 4 inches apart, and cover with 2 inches of compost or soil. Place the pots near a bright grow light with sufficient airflow to prevent the growth of gray mold. When leaves start to grow—and after the last frost—the plants can be transplanted.
Ranunculus Care Tips
Light
Hardy perennial ranunculus should be planted in full sun or partial shade. If they are planted in full shade, they will not flower.
Soil and Water
If you’re eager to add ranunculus blooms to your garden, supply them with moist, well-draining soil that won’t dry out but isn’t waterlogged. Water established plants in the morning once a week. Stop watering when the plant becomes dormant in the fall and stops producing flowers.
Temperature and Humidity
The plants thrive best when grown in mild temperatures in spring, summer and into the start of autumn. Ranunculus plants can't handle freezing temperatures. Gardeners in colder zones can dig up the corms and store them in a cool, dry place for the following year. Grow ranunculus in average humidity. High humidity increases the chances of fungal infections.
Fertilizer
When border-planted ranunculus start to grow, the plants appreciate regular feedings with a balanced fertilizer, following the product instructions, or bone meal. Plants that grow in meadows or along ponds and streams do not need feeding.
Pruning
No pruning is needed, but remove any damaged or diseased foliage, sterilizing your shears before cutting the plant. Deadhead ranunculus blooms to encourage additional blooms.
Potting and Repotting
Ranunculus plants grow well in containers as long as the container offers excellent drainage. Choose a container large enough for several corms spaced 3–4 inches apart and fill it to within 4 inches of the top with well-draining potting soil. Soak the corms for three to four hours and place them in the container with their claws facing downward. Cover with an additional 2 inches of potting soil. Water the container and place it in a location with a temperature of about 60°F. No light is necessary until foliage appears.
Repotting isn't necessary for ranunculus plants grown as annuals. However, those grown in containers as perennials will spread and eventually outgrow their containers. In that case, repot in a larger container using fresh potting medium, or divide the plants and repot.
