Spring Planting Ranunculus bulbs

Why should you choose ranunculus bulbs?

Ranunculus bulbs are a top choice for gardeners looking to add colour and elegance to their outdoor spaces. These bulbs produce stunning, rose-like blooms in a wide range of vibrant colours, from bold reds and yellows to soft pastels, making them perfect for creating striking displays in borders, beds, or containers. 

One of the standout features of ranunculus is its versatility. They thrive in both garden borders and containers, offering flexibility in where you plant them. Additionally, ranunculus are ideal for cutting, making them a popular choice for those who enjoy bringing fresh flowers indoors. Their long vase life means you can enjoy their beauty for days after cutting.

Despite their delicate appearance, ranunculus bulbs are relatively easy to grow, and with just a bit of extra care—like soaking the claw-like corms before planting—you can greatly improve their performance. With their stunning blooms, long flowering season, and ability to produce excellent cut flowers, ranunculus is a wonderful addition to any garden, providing plenty of beauty from late spring to early summer.

How to plant ranunculus bulbs

Planting ranunculus bulbs is simple and rewarding, giving you beautiful, rose-like blooms. Follow these steps to ensure your ranunculus thrives:

Pre-soak the corms: Ranunculus corms, which resemble small claws, benefit from soaking before planting. Soak them in room-temperature water for 3-4 hours to help them absorb moisture and sprout faster.

Choose the right location: Ranunculus prefer a sunny spot with well-drained soil. If you're planting in garden beds, ensure the soil drains well to avoid rot. In containers, use a good-quality, well-draining potting mix.

Plant at the right depth: Plant the corms with the claws facing downwards, about 5 cm (2 inches) deep. Space them 10-15 cm (4-6 inches) apart to give each plant room to grow.

Water carefully: After planting, water thoroughly to help the soil settle around the corms. Ranunculus prefer consistent moisture but be careful not to overwater, especially before the shoots appear.

Fertilise for stronger growth: Once the shoots emerge, feeding with a balanced, slow-release fertiliser will encourage healthy growth and abundant blooms.

Support if needed: Ranunculus can grow between 30-45 cm (12-18 inches). If they are in a windy location or the stems seem weak, consider adding small stakes for support.

With these simple steps, your ranunculus will reward you with stunning, long-lasting flowers perfect for cutting or brightening up your garden.

FAQs 

When is the best time to plant ranunculus bulbs?

Ranunculus bulbs are best planted in autumn, but they have to be protected from winter frosts. If planting in spring, aim for 4-6 weeks before the last frost, as ranunculus thrive in cooler temperatures but are sensitive to freezing.

How deep should I plant ranunculus bulbs?

Plant ranunculus bulbs approximately 5 cm (2 inches) deep with the claw-like corms facing down. Make sure to space them 10-15 cm (4-6 inches) apart to allow for growth and proper air circulation.

Can ranunculus grow in containers?

Yes, ranunculus thrives in containers. Choose a well-draining pot and use a high-quality, loamy potting mix. Ensure the container is placed in full sunlight for at least 6 hours a day, as ranunculus prefers sunny locations.

How often should I water ranunculus?

Water ranunculus regularly but avoid waterlogging the soil. Keep the soil moist during the growing season, but reduce watering as the flowers begin to fade and the foliage dies back. Too much water can cause the corms to rot.

How do I prepare ranunculus bulbs before planting?

Ranunculus corms should be soaked in room-temperature water for 3-4 hours before planting to help them "wake up" and start the sprouting process. Pre-soaking the corms speeds up root development and enhances their growth.
