Rhipsalis cacti are rare succulents, the shoots of which are mostly hanging. This is why amateur gardeners like cacti to cultivate them as an ampelous plant. About 40 species are known that, with proper care, not only develop the leaves or braid-like interwoven shoots, which are unusual for cacti, but also bloom splendidly in spring. Berry-like, smooth fruits develop from the countless small white, cream-colored or pink flowers. They are often kept as indoor plants, but also feel good in the garden in summer. Like all cacti, they are easy to care for and can live for many years.

maintenance

Rhipsalis cacti do not hibernate and can therefore be kept indoors all year round. Anyone who allows them to stay in the fresh air in summer will be rewarded with a richer flowering. Since these cacti are not hardy, they have to be taken indoors when the temperature drops, in the heated winter garden or in the greenhouse. The most important care instructions are presented below:

  • sunny to partially shaded location
  • protect from blazing midday sun
  • place outdoors protected from rain and wind
  • only watering if the soil is well dried
  • no calcareous tap water
  • rainwater is ideal
  • Avoid waterlogging at all costs
  • Do not let the plant balls dry out completely
  • Evaporation tanks ensure high humidity
  • In winter, additional water-filled bowls on the heater
  • give cactus fertilizer every 14 days
  • only fertilize up to the opening of the bud
  • regularly check for pests
  • water less in winter
  • do not repot during the winter

The ideal substrate for Rhipsalis cacti is a mixture of 2/3 peat and 1/3 sharp sand. This is cheaper than buying special cactus soil, but supports growth and flowering just as well. Since this type of cactus has only a few and very small roots, repotting is rarely necessary. If the planter is still completely rooted, the best time to repot is spring.

Diseases and pests

Like most cacti, the Rhipsalis are not immune to diseases and pests. Often the infestation with mealybugs or mealybugs can be observed, which shows itself through fine, woolly webs on the leaves and shoots. The tiny lice suck out the sap and weaken the cactus. At the same time, they release a poison into the shoots or leaves, which causes a yellow discoloration and ultimately causes the rhipsalis to die. As a first measure, the infected plant should be quarantined so that the mealybugs do not spread any further. Pesticides that are produced from the extract of the neem tree have proven to be successful in combating them. In addition, experienced hobby gardeners report good experiences with the lacewing larvae, which are available in specialist shops.

Rhipsalis vermehren

These cacti are preferably propagated from cuttings, which are cut from the mother plant in spring or summer. The severed shoots are 8 cm to 15 cm long. After cutting, they are stored in a dry and cool place for a few days until they are about 4 cm deep in a suitable cactus substrate or a peat-sand mixture.

The cultivation vessel is placed in a light to partially shaded location that is not exposed to blazing sunlight. The optimal temperature for this phase of reproduction is between 20 ° and 25 ° degrees Celsius. Since the cuttings need a high level of humidity, a plastic sheet is placed over the container and fastened with a rubber band.

In order to avoid the formation of mold, the film is ventilated for a few minutes every day. On this occasion it is checked whether the substrate is slightly damp. Under no circumstances should waterlogging occur here, so the seed pot should not stand on a saucer in which the irrigation water can collect.

As soon as the first young shoots appear, air holes are first cut in the film before it is completely removed a few days later. In this way, the young Rhipsalis gradually get used to the room climate.

Incidentally, an old aquarium is perfect for growing cactus cuttings. This is covered with a layer of gravel so that waterlogging cannot occur. A room temperature of 18 ° Celsius is then sufficient to ensure that the aquarium is around 22 ° Celsius and that there are ideal climatic conditions for the young plants.

Rhipsalis – the cacti with many faces

There is hardly a cactus genus that presents itself in such diverse forms as the Rhipsalis. German hobby gardeners refer to them as coral cactus, rush cactus, whip cactus or rod cactus. The around 40 species of Rhipsalis appear once as leaf cactus, then again with meter-long, thin shoots or triangular branches. In any case, the hobby gardener is spoiled for choice when it comes to cultivating Rhipsalis in his home or in the garden.

The pompous overhanging growing species are the ideal ampelous plants, whereas the species with the lush, short branches do very well in the flower pot. As multifaceted as their growth forms are; The Rhipsalis cacti all have one thing in common: They are very easy to care for, as long as they are given a suitable location. They are not hardy; But they like to spend the summer in the fresh air and thank you for it with a particularly opulent flower. Those who know how to dose the dose of water correctly will enjoy the mostly exotic-looking cacti for many years. Garden enthusiasts who cannot get enough of them can easily propagate Rhipsalis with the help of cuttings.
