in the house

Ranunculus is suitable as a houseplant for a short time. The colorful plants do well in a bright, not too sunny place. The cooler the location, the longer the shelf life. A house entrance that is not too warm or the stairwell is ideal. In the heated living room, the buttercup is a floral decoration comparable to a bouquet of flowers that blooms for a maximum of 1 week at temperatures above 20 °C.

What is the best way to plant my ranunculus?

planting material

Ranunculus are mainly planted as seasonal flowering plants in spring. In combination with forget-me-nots, daffodils, daisies, primroses and much more, colorful window boxes and containers can be designed. Even in groups on the bed or grave, the classics bring color quickly and easily after the winter. It is best if you plant the buttercup from the culture pot in a larger container or in the ground. By repotting, you give the flowering plant a larger root volume and reduce the watering effort. However, repotting is not absolutely necessary. Use good quality potting soil for repotting and add a layer of expanded clay to the container for better drainage.


Another option for planting Ranunculus is by tubers. Like dahlias and gladioli, these hard storage organs can be placed outdoors from May. It is important that the soil is deeply loosened and free of weeds. When planting, make sure the toes are pointing down with their tips. If planted early, the young plants may be damaged by late frost. The young foliage in particular is sensitive to frost.

Our gardening tip: before planting, soak the tubers in a bucket of water for 24 hours to allow them to swell.

What is the best way to care for my ranunculus?

In addition to the constant water supply, Ranunculus only requires regular cleaning of the withered flowers. With the right care, new buds are formed and no seed formation takes place. Fertilization is not necessary when using high-quality potting soil. The duration of flowering essentially depends on the temperature and the amount of sunlight. After flowering, further cultivation is usually unsuccessful.

How do I water and fertilize my ranunculus?

Ranunculus are extremely easy-care plants, but regular watering is essential. How often you have to water depends largely on the location and the radiation. The so -called demand- oriented watering means the even moisture in the soil. When watering, make sure that the water does not get over the flower and that the soil dries up a little before the next watering.

The nutrient content in the pot when you buy it is sufficient for the plant and therefore fertilization is not absolutely necessary. If necessary, liquid fertilization can be carried out with high-quality garden fertilizer. It is important that the root ball is well moist to avoid root damage.

Ranunculus bulbs are supplied with flower bulb power when planted and continue to grow well without additional fertilizer. On light sandy soils, additional fertilization with organic fertilizer can be carried out after sprouting.

Our gardening tip: Above all, protect the young shoots from snails.

pests and diseases

With proper ranunculus care, disease rarely occurs. As with other plants, pests can infest the garden and specimens in pots. The most common is aphid infestation, but this does not play a major role and usually only represents a visual impairment. If the infestation is severe, the affected leaf or plant can be removed.

Wetness is usually the problem in winter and the tubers rot. In principle, the flowers tolerate temperatures down to 0°C without damage. With proper overwintering, the Ranunculaceae are perennial.

How do I overwinter the tubers correctly?

The right place for storing the storage organs is light, dry and at temperatures around 5°C. Unheated basements or frost-free garages are ideal for winter storage. In October, dig up the storage organs and place them in buckets filled with sand at the wintering site until spring. Watering is not necessary during this time.
