How to Plant Ranunculus Indoors


Ranunculus--also called buttercup--blooms generally in the spring and early summer. Often, many people refer to their underground root structures as bulbs; however they are actually tubers.While ranunculi are normally planted outdoors, they make excellent indoor plants. You can plant several ranunculi together in one pot if desired.

Step 1

Soak ranunculi tubers overnight prior to planting to hasten root formation. Do this at room temperature.

Step 2

Fill your planting container with a high quality potting soil. You can use any size container that is at least 6 to 8 inches deep and has holes for good water drainage. The pot's diameter can vary, but it should be at least 4 inches wide, a size that will hold one plant.

Step 3

Use your hands to plant ranunculi tubers so that the claw-like end is facing down. The top should be 2 inches beneath soil's surface. Space multiple ranunculi about 4 inches apart from one another.

Step 4

Water well and pat the soil firmly down to get rid of any air pockets. Place the container in a sunny area of your home. A south facing window is best.
