How and when to plant ranunculus bulbs
Ranunculus, also known as Persian buttercup, is a highly decorative garden flower valued for its lush, layered petals and vibrant colours. It is an excellent choice for flower beds, containers or as a cut flower. To achieve a stunning display, ranunculus bulbs (also called corms or claws) should be planted correctly and at the right time.
When to plant ranunculus bulbs
The best time to plant ranunculus bulbs is in spring, during March–April, once the risk of frost has passed. In areas with mild winters, they can also be planted in autumn, September–October, for an earlier flowering. It is important to wait until the soil has warmed before planting.
Where to plant ranunculus bulbs
Ranunculus prefers sunny spots, receiving at least six hours of direct sunlight per day. The soil should be loose, well-drained and rich in organic matter. Avoid waterlogged areas, as bulbs are prone to rot. They are suitable both for flower beds and for large pots on terraces or balconies.
Step-by-step planting guide
- Soak the bulbs (known as "claws") in lukewarm water for a few hours before planting.
- Dig holes 5–7 cm deep.
- Place the bulbs with the claws pointing downwards and the rounded side facing up.
- Leave 10–15 cm spacing between bulbs.
- Cover with soil and water lightly.
Care after planting
Water regularly, but avoid excess moisture. Apply a mulch layer to maintain soil moisture and protect bulbs from sudden temperature changes. Remove faded flowers to encourage continuous blooming. In regions with cold winters, lift the bulbs after flowering and store them in a cool, dry place until the next planting season.
Summary
Ranunculus bulbs are best planted in spring or autumn, in sunny positions with well-drained soil. With proper planting and simple care, this elegant flower will reward you with a romantic, colourful display that enhances both gardens and containers.
