Depth and Spacing: Plant the corms 5-8” apart and 2” deep with the claw side down. Alternatively, you may sprout the corms before planting them into the garden or into containers. In this case, fill a seed tray with about 1" of damp growing mix. Position pre-soaked corms (see below) closely together on top of the mix and cover with another 1" of moist growing mix. Keep tray in a dark place for 10 days at 50-60°F. When white roots are visible, the corms are ready to plant. Planting Tips: When ranunculus corms are dormant, they are very hard and dry. You can help them sprout by soaking the corms in room temperature water immediately before planting. Soak them for 3-4 hours (no longer!). To prevent the soaking water from becoming stagnant, run a trickle of water from the faucet into the bowl.
