Aasblume, Stapelia grandiflora - care

The Content Of The Article:

The most beautiful name has the Aasblume now not and unfortunately this is also an accurate description of the smell of flowering. What she lacks in fragrance makes the Stapelia grandiflora but with exotic beauty. Care must be taken to ensure that it can develop fully and be preserved.
The carrion flower or Stapelia grandiflora, as the South African plant is also called, is particularly charming by its flowering. Even if it does not bloom, the succulent plant with the unusual leaves is an eye-catcher. However, to ensure that it grows properly and starts to flower, the carrion flower needs the right care. But with the right guidance, these are so easy that even beginners and all plant fans can handle it well without a green thumb.
The carrion flower is native to South Africa and grows in sunny places in its country of origin. The location in the living room or on the balcony must therefore also be very bright. The only exception to this is in midsummer. At very high temperatures Stapelia grandiflora should be protected from strong, blazing midday sun. At the window seat, a dark curtain or a roller blind is enough, in the open, the south side should simply be avoided. Protection against wind is not necessary, but heavy rainfall can lead to the breaking off of plant parts. A light canopy or a hanging over the carrion flower plant are therefore advisable.
The carrion flower needs a loose, well-drained substrate. Suitable soil for Stapelia grandiflora is commercially available plant or potting soil, which is mixed for loosening with coconut fibers and sand or gravel. If fresh substrate is selected, no further fertilization is necessary. For earth that is recycled, a preparation should be done with appropriate means.
to water
When water is the Aasblume frugal. Fresh and even hard tap water is good for them, but rainwater or stale tap water are still the better choice. Casting takes place only when the uppermost layer of the substrate has dried. Of course, this is faster in the summer or when the heating air is dry than at lower temperatures or a Stapelia grandiflora that is in the bathroom. For larger carrion flowers in small pots, checking the moisture in the substrate with the thumb sample is difficult. In contrast, a small amount of substrate can be removed by inserting a straw into the ground and pulling it out slightly at an angle. If the substrate shakes out easily, or if it is not found in the stalk, it will be time to water it. If, on the other hand, it sticks to the plastic or if it shows signs of moisture, the casting can still wait. Tip: Instead of pouring from above, the carrion flower is better tolerated when placed in a full water bucket or bowl. After about half an hour, the substrate has become soaked and the Stapelia grandiflora can leave the water bath.
If the carrion flower stands outdoors and is kept in a cool winter, it can be fertilized from May to September. If the Stapelia grandiflora is cultivated in the room all year round, fertilization can start in February and continue until October or even November.
In any case, suitable Kali-stressed fertilizers, which can be added directly to the irrigation water. A weak dosage of every four weeks is enough. Tip: With an annual repot into fresh substrate, can be dispensed with an additional fertilization usually completely.
The Aasblume does not need a shape cut. However, it may happen that it grows unfavorably out of the pot and is no longer stable due to overhanging parts. Then it is possible to shorten it accordingly. However, this must be done very carefully. On the one hand, the interfaces must not be crushed, on the other hand, they are extremely susceptible to stalk rot. Contact with water should therefore be avoided at all costs.
The Stapelia grandiflora only flowers when it gets enough light. It therefore requires a window seat or a sunny location outdoors. If they can not be offered during the summer, the use of plant lamps is a good alternative. With these it is even possible not to admire the flower until late summer. But beware! Although the flowers look pretty, they spread an unpleasant carrion smell - hence the name of the carrion flower. This smell attracts flies magically and helps the plant in fertilization. However, the insects can also lay their eggs on the plant. If you want to avoid this, you should carry out regular checks.
The carrion flower can be multiplied both by seeds and by offshoots. However, the seeds are bound to a fertilized flower, which makes this propagation unsafe game of patience.It is therefore easier and faster to cut off offshoots carefully and place them in substrate. The respective interfaces must again be kept dry until they have completely closed.
For overwintering, the Aasblume have two options. On the one hand, it can still be bright but slightly cooler - but the temperature should not fall below 15┬░ C. With this attitude, it requires less water and also the fertilizer can be completely adjusted until the next spring. However, if the Stapelia grandiflora stands by a window in summer anyway, it can remain there in winter. The watering can usually be reduced a bit, fertilization should be avoided from November to February.
When repotting the carrion flower, there are no special considerations. Only caution must be exercised so that no plant parts break off.
Typical diseases and pests
The carrion flower is not susceptible to pests. On the other hand, it can suffer more frequently from fungal infections. The best prevention is to dip the plant without moisturizing the leaves. In addition, of course, casting quantity and frequency must be adjusted. If the Stapelia grandiflora is too moist, it can cause the roots and leaves to rot. Here then only help the repot and the use of a fungicide.

  • Scale insects
A louse attack can be recognized by sticky spots on the leaves. These insects are about 5 mm in size and sit on both the leaf top and leaf undersides and on the trunk. The females have a white to brown, round or oblong shield under which the eggs are sitting.
Scale insects multiply explosively. Their fight is tedious and difficult. In addition to scraping with alcohol can be used to combat an oily spray spray or a systemic means in the form of sticks for insertion into the soil or granules. These methods are not unproblematic. In any case, the plant must be isolated to prevent the spread of scale insects on other plants.
  • mealybugs
Mealybugs can be recognized by white webs on the leaves, reminiscent of balls of wool. The fight is similar to that of scale insects.
Frequently asked questions
  • Why does not the carrion flower bloom? - The Stapelia grandiflora may take several years to flower for the first time. But they will stay off if the succulent plant is not bright enough. A change of location or the use of a plant lamp usually help.
  • Why do black spots form on the carrion flower? - If the leaves show dark discolorations or even clearly delineated, black spots, this is an indication of a fungal attack. To save the carrion flower, it must be treated with a fungicide and repotted.
care errors
  • If the carrion flower is too dark, it does not produce any flowers.
  • If the carrion flower is watered too hard, it gets black spots on the trunk. This is a fungal attack that the plant can easily enter.
  • If the location of the carrion flower is too cool, this can also lead to fungal infestation. In both cases, the plant must be treated with a fungicide.
  • If the carrion flower is too warm in winter, it will not bloom in the next summer.
  • If the humidity is too high, mildew can occur. This must be treated with a fungicide.
Worth knowing about the carrion flower soon
The carrion flower (stapelia), also called Ordensstern, comes from South Africa and owes its German name to the smell of flowers, which smell of carrion. These flowers are appreciated for their attractive appearance. They are star-shaped, brownish, purple or yellow and grow individually on short stalks. They are between 5 cm (e.g. Stapelia variegata) and 35 cm (Stapelia gigantea) big.
  • The carrion flower needs a bright location with direct sunlight throughout the year.
  • It needs a well drained soil. Therefore, it is best planted in a mixture of potting soil and sand or gravel and peat.
  • Since carrion flowers grow very fast they need to be repotted more often.
  • This should happen as soon as the trunk reaches the pot edge, if possible in spring.
  • If necessary, you can also transplant in the summer or early autumn. Then you can give some cactus fertilizer.
to water
When casting, a little care is needed: If the soil is too humid, rotten the shoots, the soil is too dry, shrivel the shoots and eventually die. During the summer, you can place the carrion flower in a bowl of water and wait until the top layer of soil becomes damp. Then take out the plant. This is repeated as soon as the uppermost layer of earth has dried. In winter, put it in water only once every two weeks and remove it again before the top layer of soil is damp.


From spring to autumn, the carrion flower should be fertilized every four weeks with high-potassimum fertilizer or cactus fertilizer.
Hibernate & Cut
  • The temperature of the site should not fall permanently below 10┬░ C in winter.
  • Aasblumen need not be cut, unless you want to remove rotten parts.
Aasblumen can be propagated by seeds or cuttings: The seeds germinate at temperatures around 22┬░ C after approximately one week. Cuttings are cut out of side shoots in summer. Often, however, you can also pull out a side shoot with the roots. Break off the roots, cut the break point clean with a knife and let the interface dry out for four to five days. Then you put him in earth.
  • Once the cut has been cut from the mother plant, the interface must be protected from water for four to five weeks.
  • Penetrate water at this time, the plant rots and dies.
  • In winter you should check the carrion flower regularly for fungal infestation and if necessary treat it with a fungicide.
Popular species
