Cut Flower Grower's Tip

Italian Ranunculus performs best when planted during the cooler months, allowing plants to establish strong root systems before flowering in late winter and spring. Plant deep. Don't be afraid to cover some of forming leaves to ensure the Ranunculus corm that is forming is well under the soil. Check them as they grow to ensure the soil hasn't dislodged exposing the corm. I find birds can often pull them out for fun. Fertilise regularly throughout the season
