When is the time to start ranunculus in the greenhouse and can they be transplanted to the outside garden in Colorado, and if so what is the correct procedure for this? |
Ranunculus can be planted outdoors 1-2 weeks after your last frost. In your region, plan on transplanting them outdoors about the second week of May. Ranunculus needs 2-3 weeks of prechilling prior to planting. Begin now by sealing in a plastic bag and placing in the refrigerator for 2-3 weeks. Then plant in trays or flats of moistened growing medium. Seeds need to be barely covered with growing medium; roots should be planted 2" deep. Keep your plants in the greenhouse until the soil warms up outdoors, then transplant to a sunny site with well draining soil. |
