Sch├Ânmalve, Zimmerahorn, Abutilon megapotamicum - care

The Content Of The Article:


The beautiful mallow Abutilon megapotamicum is a semi-climbing and semi-shrubby species, also known as the maple and velvetleaf. The upright shrubs form overhanging shoots. The special feature of this plant are its flowers. From a fire-red, balloon-like calyx protrude bright yellow flower crowns with brown stamp. When cultivated in a tub, for example on a balcony or terrace, this beautiful mallow can reach growth heights of up to 150 cm. The hibernation should be done frost-free in any case.

Location and ground

Common to all species is the claim to a warm and sunny to partially shaded location without direct sun. Optimal are a few hours of sun in the morning and in the evening. In a sunny window seat must be provided for sufficient shade. From mid / end of May to the autumn she can go outside. Outside, it should be located on a wind and rain sheltered place and protected from the blazing midday sun. The tender shoots of the Sch├Ânmalve are relatively sensitive and could be damaged unprotected. This plant thrives best at temperatures between 19 and 21 degrees, in winter correspondingly cooler. The substrate should have a pH between 6.0 and 6.8. It can be a compost-based potting soil that is permeable and has the highest possible humus content. Not to mention a drainage layer to protect against waterlogging.
Tip: If the fair mallow leaves lose, this can be due to strong temperature fluctuations, too dark and drafty location but also to a change of location.

Pouring and fertilizing

From spring to autumn should be poured abundantly and regularly, without causing waterlogging. The substrate should always be evenly moist and the root ball should never completely dry out, then the Sch├Ânmalve would react with leaf shedding. Before each casting, the top substrate layer is allowed to dry slightly. Excess water in the saucer or planter is to be removed regularly. Fertilization should also be regular, from April to August / September once every 2 weeks. For this u. a. commercially available liquid fertilizers, flowering fertilizers or fertilizer sticks for flowering plants.


  • The Sch├Ânmalve tends over the years to balding and a sparrigen growth.
  • Therefore, a regular pruning is recommended.
  • This can be done in early spring or directly after flowering.
  • The Sch├Ânmalve also tolerates a stronger pruning, up to half or to the old wood.
  • In addition, cut out unsightly or annoying as well as withered shoots.
  • If the correct cutting time was missed, it can be blended in the fall.
  • In this case, cut before entering the winter quarters.
Tip: So that the plants remain compact and do not corrode, young plants can be thinned out several times a year.

Sch├Ânmalven are basically not hardy and need a frost-free hibernation in a bright room at temperatures between 10 and 12 degrees. Above 15 degrees, the room temperature should not rise. In winter, water is poured more sparingly, the cooler the wintering the less watering. The bale should not completely dry out even in winter. Fertilizer is now completely dispensed with. Before putting the plants outside again in the spring, they should be hardened to prevent burns from the sun. It is best to put them for the first 1-2 weeks in a partially shaded place. After these 2 weeks the beautiful mallow can then be put to its final place.
Tip: Strong temperature fluctuations should be avoided, they can lead to leaf and flower shedding.


  • If the pot is heavily rooted, repot Abutilon megapotamicum.
  • The best time for this is in March.
  • First, remove the plant from the pot and remove the old soil.
  • Also cut off dead root parts.
  • The new planter should only be slightly larger than the old one.
  • Drain holes and drainage layer indispensable, so that excess water can drain.
  • Immediately after planting shorten the Sch├Ânmalve by about one third.
  • This results in a better branching.
Tip: After repotting, the plant should not be exposed to direct sunlight for the first 2-3 weeks. Older specimens should possibly be repotted annually.


The simplest and most effective form of propagation is over head cuttings. These are cut in spring, they should be about 8-12 c long. The bottom leaves are removed and large ones shortened if necessary to keep the evaporation as low as possible. Then you put one or more cuttings in growing substrate, moisten this and covers the first 3-4 weeks a translucent film over it. The soil temperature should be around 22 degrees.In order to prevent rot and mold, the film has to be removed from time to time and the whole thing ventilated. Place the culture container in a warm and bright but not sunny place. For rooting Abutilon megapotamicum requires ambient temperatures of 19-22 degrees. After rooting, which is recognizable by a new shoot, the young plantlets can be planted in the garden.
Tip: A suitable Anzuchtsubtrat can be z. B. from sand and peat bog in equal parts also produce themselves.

When sowing, the seeds should only be lightly covered with soil, because they are light germs. It is best to use a room greenhouse. Place seeds in seed soil, squeeze lightly and moisten substrate. Until germination, it should always be slightly moist and never dry out. To avoid mold or rot, remove the cover here and there more often. Under optimal conditions, the seeds germinate within 2-3 weeks.
Tip: If you use seeds from your own harvest, it may happen that the new plants have different properties than the mother plants. This is the case when the mother plants are hybrids.

Possible pests

White fly
Infestation often occurs when the room air is too dry. It shows itself by the fact that the leaves turn yellow, dry up and fall off and of course on small white flies on the plant. The number of adult animals can be reduced with yellow boards or yellow sticks. For the control of the larvae, systemically acting preparations from specialist retailers are available. Among the natural predators include slipper and Umzwespen, which can be purchased in N├╝tzlingsversand. Preventive should be paid to optimal site conditions and care.
Aphids attack mainly young shoots and flower buds. Stunted shoot tips and crippled flowers may indicate an attack, as well as sticky honeydew on the leaves. If there is an infestation, you can shower off the plant thoroughly, not forgetting the undersides of the leaves. Before that you put the whole pot in a plastic bag that you close at the top so that no lice can fall onto the substrate. In case of a strong infestation chemical agents from the specialized trade help. To dispense with chemistry, you can also use natural predators such. Lacewings, gall bladder or ladybug.
spider mites
A spider mite is shown on fine white webs, especially in the leaf axils. In contrast, spraying helps with plant sown or suitable Niem├Âlprodukten. Here, too, beneficial insects such as lacewings, raub bugs, gall midges, parasitic wasps or ladybugs can be used.
Tip: Regardless of which pests the plants are infested, they should in principle be immediately isolated from healthy plants to prevent infection or spread.
ConclusionThe hanging Sch├Ânmalve can grow under lush conditions and become relatively large under optimal conditions. The attractive flowers make the plant an eye-catcher throughout the summer. The care is quite modest, only frequent relocation, too dark locations and stronger temperature fluctuations should be avoided.
