Ranunculus plant - cultivation and care of A-Z: plant

The ranunculus was once as popular in Europe as the tulip. Unfortunately, that changed towards the end of the 19th century. People lost some interest in the beautiful summer flower. Other flower species were now more popular. For a long time, the ranunculus was therefore almost forgotten. Fortunately, that has long since changed again. For many years, this fascinating plant has become increasingly popular again. The reasons for this renaissance are obvious: Ranunculus score with a fascinating flowerage and are also easy to care for.

Origin, growth and flowering

The original home of Ranunculus asiaticus, the Latin name of the ranunculus, is the Orient. From Turkey, this fascinating plant came to Western Europe in the 16th century. It is a typical bulbous plant and belongs botanically to the family of the Hahnenfußgewächse. This also means that the ranunculus is poisonous. The protoanemonin it contains makes it completely inedible to humans and animals. They are known as so-called early summer blooms, which develop their full color between May and July. Depending on the variety, ranunculus are between 20 and 40 centimeters high and about 20 centimeters wide. They bloom in a great variety of colors. The color spectrum, which serve constant new breeding, knows since then hardly borders. The most common colors are yellow, orange, pink, red and white.

Location and ground

Ranunculus like the sun, but no direct sunlight. This is especially true in the summer for the brutal midday sun, which definitely does not do the plants good. Ideal is an absonniger or partially shaded location.
Tip: By combining with so-called accompanying plants such as the goose cress, the sun protection or shade can be produced.
The site should also be reasonably secure. Whipping winds do not tolerate the ranunculus as well as heavy downpours. In general, the topic of water: The ranunculus likes it moist, but does not tolerate moisture. Above all, waterlogging must therefore be avoided. She would quickly kill the plant. In a loamy soil in the garden should therefore be created a drainage in the ground. Incidentally, this is also recommended if Ranunculus are cultivated in plant pots. A humus-rich substrate, which was mixed with sand or some gravel, has proven itself as a soil.

Sowing or planting

In retailers you get Ranunkeln either as a seed or as flower bulbs. Which method one chooses is ultimately a matter of personal taste. Sowing works just as well as planting. Sowing of the seeds takes place in the autumn - and not directly to the outside. Rather, a cultivation in the flowerpot is required to protect the young plantlets from the winter cold can. The procedure is as follows:
  • Seeds gently into a nutrient-rich substrate
  • Water well, but avoid waterlogging
  • Place the planter in a warm and bright place
  • If necessary, cover with a transparent plastic wrap to achieve a greenhouse effect

After germination, the plants form small, elongated tubers, which remain in the vessel until they are planted outdoors. If the ranunculus continues to grow in a plant pot, it should definitely be repotted in the spring. However, if it is planted directly in the garden, it is crucial that the weather conditions are right. Ground frosts are the early death for the ranunculus. The months of March and April have proven to be ideal planting times in spring. Planting is best done as follows:
  • First place the tubers in a water bath for three to four hours
  • Water well the soil for the tubers
  • Even then put the tubers about five centimeters deep into the soil and cover with soil
  • then pour well again, but avoid waterlogging
  • keep the floor always moist afterwards


As already mentioned, ranunculus are extremely easy to care for. If the location and soil conditions are right, then you hardly have any work with the plants. The only important thing is that the soil is kept permanently moist. If the ranunculus is outdoors and does not rain, it must be cast. This applies both to varieties planted directly in the garden and to those planted in the plant pot. It also means, of course, that the humidity of the earth must be checked regularly. An excess of moisture can cause the leaves of the plant to turn yellow or even rot the tubers.
On the other hand, too little water quickly causes the plant to dry up or it does not even bloom. During the flowering period from April to July must be fertilized necessarily.The plants need in this phase a lot of nutrients that are usually no longer contained in the soil. Fertilization can be done in two different ways:
  • through the direct administration of compost
  • by commercially available flower fertilizer in the irrigation water
Especially with varieties that have very large or spreading flowers, a regular fertilization is essential, otherwise the ranunculus would starve in the truest sense of the word.


The usual plant cut is actually not necessary with ranunculus. The above-ground, ie visible parts of the plants are dying anyway in autumn or in winter, which is why the growth can not be influenced by a cut. By certain cuts, however, you can extend the flowering time, in part significantly. The following should be noted:
  • Flowers that begin to wither, be sure to cut to encourage the plant to form new buds
  • Remove dead leaves immediately to ensure better growth and protect against fungal attack
  • apply a thinning cut on very close together Ranunculus to create more space
The cut should always be done with a well-functioning secateurs or with a sharp knife. It is always important to be as careful as possible in order to avoid major injuries to the plant.

Diseases and pests

Ranunculus - Ranuculus asiaticus

Ranunculus have two enemies - mildew and snails. If the mildew on a plant occurs, it should be removed immediately to prevent the spread of the infection to other plants. You may be able to try to treat an infected plant with fungicides. Snails in turn can be kept relatively easily with a worm fence or with slug pellets from the Ranunkel.
Tip: If the ranunculus has aphids, it is best to combat it with nettle stock.


Those who do not want to buy seeds or tubers regularly, can take advantage of a special feature of the Ranunculus. During the year she trains so-called mother tubers, namely small breeding tubers. These can then be planted directly next spring as an offshoot again. Alternatively, large tubers can be easily split in late autumn and then replanted separately in spring. Thus, in the best case, a doubling of the number of plants can be achieved. And finally, there is still the opportunity to win seeds from the flowers. These must, however, be withered and well matured.


Ranunculus are not hardy plants. During the winter months, they must therefore be specially protected. There are basically two options. Either leave the tubers in the ground, but cover them well with compost, brushwood and fir green, or dig them out and then store them dry and frost-free at temperatures of six to eight degrees Celsius. The latter should definitely be used with all Ranunkeln that grow in a planter. Next spring, the tubers can then easily be replanted.
