What Are Ranunculus Bulbs

When And Where To Plant Ranunculus Bulbs

The best time to plant ranunculus bulb depends on your climate and growing zone. Ranunculus are not very cold-hardy, so they need to be protected from freezing temperatures. If you live in a warm area (zones 8-11), you can plant them in the fall, and they will bloom in the spring. If you live in a cooler area (zones 3-7), you can plant them in the spring, after the last frost, and they will bloom in the summer.

How To Plant Ranunculus Bulbs

Before planting ranunculus flower bulbs, you must soak them in water for a few hours or overnight. This will help them hydrate and sprout faster. Then, it would be best to prepare the soil or potting mix by loosening it and adding some organic matter, such as compost or manure. This will improve the fertility and texture of the soil and help the plants grow better.

To plant a ranunculus flower, dig a hole about 2 inches deep and 4 inches wide, and place the corm in it with the pointy end facing up. Cover it with soil, and press it lightly. Space the corms about 6 to 12 inches apart, depending on the size and variety of the flowers. Water them well after planting, and keep the soil moist but not soggy.

How To Care For Ranunculus Flowers

Ranunculus flowers are not very demanding, but they do need some basic care to thrive. Here are some tips to keep them healthy and happy:

  • Water them regularly, especially during dry spells, but avoid overwatering or flooding them. The soil should be moist but not wet, and never let it dry out completely.
  • Fertilize them monthly using a balanced liquid fertilizer, such as 10-10-10. Follow the instructions on the label, and apply it to the soil around the plants, not on the leaves or flowers.
  • Mulch them with organic material, such as straw, bark, or leaves, to conserve moisture, suppress weeds, and protect the corms from cold or heat. Apply a 2 to 3-inch layer of mulch around the plants, but do not put it too close to the stems or crowns, as this can cause rotting or fungal diseases.
  • Deadhead them regularly by removing the faded or spent flowers. This will encourage more blooming and prevent the plants from setting seeds, which can reduce their vigour and performance.
  • Prune them lightly by removing damaged, diseased, or leggy stems. This will improve the appearance and health of the plants and promote new growth and flowering.

Leave Them In The Ground

If you live in a mild area (zones 8-11), you can leave the ranunculus corms in the ground, and they will come back the next year. However, you need to make sure the soil is well-drained, and cover the plants with a thick layer of mulch, such as straw or leaves, to insulate them from the cold.

You can also add some evergreen branches or burlap over the mulch for extra protection. In the spring, remove the mulch and the cover, and water and fertilize the plants as usual.

Dig Them Up And Store Them

If you live in a cold area (zones 3-7), you need to dig up the ranunculus corms and store them in a cool, dry, and dark place, such as a basement, garage, or shed. To do this, wait until the foliage dies back naturally, and cut it off at the base.

Then, carefully lift the corms with a fork or spade, and shake off any excess soil. Let them dry for a few days in a well-ventilated area, and then store them in paper bags, cardboard boxes, or mesh bags, filled with peat moss, sawdust, or vermiculite.

Check them occasionally, and discard any that are rotten, shriveled or moldy. In the spring, replant them as described above after the last frost.
