When to plant
Plant ranunculus in autumn in mild climates with frost-free winters. In cooler regions, start them indoors in late winter and transplant outside in early spring once the danger of hard frost has passed.
Where to plant
Choose a sunny position with well-draining soil. Ranunculus love full sun and do best in open areas where light promotes compact growth and abundant flowering. Avoid soggy spots or heavy clay unless amended for better drainage.
Preparing the soil
Loosen the soil to about 20 cm deep and enrich with compost or well-rotted organic matter. If your soil tends to hold water, improve drainage by adding coarse sand or grit. Raised beds or containers with drainage holes are also excellent options.
Preparing the tubers
Soak the claw-like tubers in lukewarm water for 3–4 hours before planting. This helps rehydrate them and speeds up sprouting. The tubers will plump up slightly as they absorb moisture.
Planting the tubers
Plant each tuber claws-down, about 5 cm deep, spacing them 10–15 cm apart. For full, lush displays, cluster 3–5 tubers together in one spot or container. Cover lightly and water gently.
After planting
Water once after planting to settle the soil, then wait until green shoots appear before watering regularly. Keep the soil lightly moist—overwatering at this stage may cause rot.
During growth
As foliage fills out and buds appear, feed with a balanced liquid fertilizer every two weeks. Remove spent blooms to encourage continuous flowering. In containers, ensure good airflow and avoid crowded planting to reduce the risk of mildew.
After blooming
Once flowering ends and leaves start to yellow, stop watering and allow the plant to dry down completely. In cooler climates, lift and store the tubers in a cool, dry place. In frost-free regions, tubers may be left in place and will often multiply for even better displays the following year.
Extra tips
Ranunculus makes a wonderful cut flower — harvest when buds are just showing color but not fully open. Combine with tulips, anemones, or muscari for a romantic spring border. Keep slugs and snails at bay, as young shoots are tender and attractive to pests.
