The best time to plant ranunculus according to experts
Whether you’re aiming for a dazzling summer display or a bright pop of colour in early spring, it’s well worth researching the best time to plant ranunculus for the specific flower bed you’re dreaming of.

Where to buy ranunculus bulbs:
With that in mind, then, experts generally advise that the best time to plant ranunculus is in March if you want them to bloom in the summertime.
‘For a summery sweep of ranunculus, you’ll want to plant them in early spring (March to April) once the risk of hard frost has passed,’ says Christopher O’Donoghue, one of the co-directors at Gardens Revived.
Christopher goes on to note that, for spring flowering, you will want to ‘plant the tubers in autumn (September to November) if you have a greenhouse or cold frame to protect them from frost.’
‘You can plant them outdoors in some areas if you cover them with horticultural fleece or mulch to protect from frost,’ he adds.
‘In wetter regions, though, you may need to lift the tubers in autumn and store them dry over winter, then replant in spring.’
