How to Grow Ranunculus Flowers


Ranunculus bulbs produce up to two-dozen flowers each during the cool weather of spring and early summer. The flowers come in shades of red, pink, orange, yellow and white, and resemble cabbage roses. The bulbs are somewhat tender and cannot survive winter weather north of Zone 7. Plant in early spring and dig them up before winter in these areas.

Step 1

Plant ranunculus bulbs in the correct season. Plant during early spring in Zone 7 or further north, and in late fall in areas south of Zone 7.

Step 2

Pick a site in full sun where the soil is well-drained. Do not plant in areas where water puddles remain after rainfall.

Step 3

Dig a hole about 3 inches deep. Add a teaspoon of powdered bulb food to the bottom of the hole. Mix it into the soil.

Step 4

Plant the ranunculus bulbs with their pointed ends facing down. Plant the bulbs 2 to 4 inches apart, depending on their size. Smaller bulbs can be planted closer together than larger bulbs. Cover with soil and gently firm it down.

Step 5

Water well. The bulbs will begin to grow in 15 to 20 days.

Step 6

Mulch the area with 2 to 3 inches of hay, shredded bark or buckwheat hulls.

Step 7

After the flowers finish blooming, cut the flower stems to ground level but not the leaves.

Step 8

In Zone 7 or further north, dig up the bulbs in fall after the leaves die down. Store in mesh bags in a cool, dry place until early spring. In areas south of Zone 7, leave the bulbs in the ground year round.
