Ranunculus corms can be grown as annuals and discarded after flowering, or lifted, stored and replanted in autumn. Lift corms when the foliage turns yellow.
To lift ranunculus corms, first cut the foliage off at ground level. Use a garden fork to lift corms from the soil, taking care not to damage them. Spread the corms on a wire rack in a cool, dry place for 10-14 days to dry them. Then store the corms in a net bag or in just-damp vermiculite until it is time to replant them in autumn.
Good airflow is important.
Common Problems: Aphids, Downy mildew, Powdery mildew, Rotten corms, Slugs and snails
Flowers in: Late winter, Early Spring days Vase Life: 10 to 12 days
If trying to save corms - after flowering let plants naturally die down, trying to keep them as dry as possible. Once their foliage has yellowed & faded fully they're ready to lift up. Once lifted trim the stalks back to the base of the plants and let fully dry out and store in a warm dry place until autumn. Corms can be replanted from about April to May. Soak corms in room temperature water for 3-4 hours before planting, stir every 30 mins to add oxygen to the air. Pre-sprout in a bed of soil or plant straight out.
