How to Grow Ranunculus From Seeds


Ranunculus is a hardy perennial flower that comes in a large variety of sizes and shapes. The flowers of the ranunculus are shaped like cups or double cups. Some varieties of ranunculus bloom in the spring, some in the summer and some species bloom in the late winter. The flowers range in color from white to pastel pink and yellow to bright red, yellow and orange. Many gardeners grow this plant from transplanted tubers, but it is also possible to grow them from seed.

Step 1

Choose an area that gets full sunlight and has good drainage. If the area frequently sits in standing water after a rain, choose another area. Ranunculus seeds should be planted after the last freeze of winter or spring is over.

Step 2

Break up the surface of the soil with a trowel or garden claw. If you are planting over a large area, rent a garden tiller to break up the soil. Add some peat moss or potting soil to the soil to give it better aeration and drainage.

Step 3

Plant the ranunculus seeds 2 to 3 inches deep. Water the area lightly after planting the seeds. Use a trickle from a garden hose or a gentle plant waterer that will not force the seeds too far beneath the surface of the soil.

Step 4

Thin out the weak ranunculus seedlings to allow the stronger ones to get larger. This will take away the competition for nutrients and give the stronger plants a better chance to survive. The plants that remain should be 4 to 6 inches apart.

Step 5

Water the ranunculus regularly to keep the soil slightly moist.

Step 6

Fertilize the soil with an organic fertilizer when the ranunculus plant starts to flower and again once the flowering has ended. A small amount of peat moss or other fertilizer can be mixed into the surrounding soil. Keep the fertilizer away from the leaves or the fertilizer can cause leaf burn.
