Allamanda: Home Care, Transplanting And Propagation, Species

The plant Allamanda is part of the Cuthrus family. It consists of about 15 different species that are represented by evergreen shrubs and vines. In nature they can be found on the territory of America in tropical areas.

In room culture the allamanda is found rather rarely, because it is distinguished by the demanding care, namely: to temperature, lighting and humidity levels. Also, the bush needs mandatory systematic pruning.

If you grow it in a pot, then it also needs a reliable support. It is also recommended that the allamanda be transplanted regularly once a year.

Brief description of cultivation

Allamanda: home care, transplanting and propagation, species

  1. Flowering. It is observed in May-September. However, the indoor allamanda blooms only in conditions as close to natural as possible.

  2. Brightness. Needs plenty of bright light.
  3. Temperature. In winter 15 to 17 degrees and in summer 20 to 25 degrees.
  4. Pouring.

    Throughout the spring and summer period, water abundantly. With the onset of autumn, reduce watering gradually, and during the winter months only when the surface of the substrate has dried approximately 30-40 mm in depth.

  5. Air humidity. It must be increased. For this purpose the bush is systematically moistened from a sprayer, and it can also be placed on a tray filled with wet pebbles or expanded clay.

  6. Fertilizer. Fertilization is carried out only during active growth with a frequency of 1 time in 20 days, for this purpose use organics and complex minerals. The dormant bush is not fed.
  7. Dormant period. Starts in deep autumn and ends in early spring.

  8. Repotting. It is carried out in the springtime. While the Allamanda is young, it is transplanted systematically once a year, and older specimens only if necessary (on average once every 2 or 3 years).
  9. Support. The bush needs a support.

    It is placed in the pot at the time of transplanting. For this you can choose a ladder or an arch.

  10. Mud. Peat, sand, humus, leaf and sod soil (1:1:5:2:1).
  11. Trimming.

    At the very end of the period of intensive growth, all shoots should be shortened by ½ part. And throughout the growing season, systematically cut out all weak stems.

  12. Propagation. Practically by single stem cuttings and by seed.
  13. Pests.

    Whiteflies, spider mites, nematodes and aphids.

  14. Diseases. Root and stem rot.
  15. Properties. The sap of the plant contains poison!

Home care of the allamander

Specialists advise, choose a bright place with lots of bright light for the allamander.

A southern window sill is best for it, and it should be taken into account that the bush responds well to not very much direct sunlight. This evergreen plant grows well in winter gardens as well as in greenhouses.

Temperature regime

In spring and summer the plant should be kept warm, the optimal temperature at this time is 20 to 23 degrees. From late November to late February, the bush should be in a cooler place (15 to 17 degrees), and watering should be reduced. Protect it from draughts, as they can cause it considerable damage.


In summer, the flower should be watered regularly and abundantly. Never allow the root ball to become too dry or stagnant. In winter moisten the substrate in the pot only when the top layer is dry.

Air Humidity

Since the plant needs high air humidity, it should be moistened regularly with a sprinkler during the active growth period. During the flowering period, while moistening the shrub, take care not to get any moisture droplets on the surface of the flowers, as this can negatively affect their ornamentation.

Also increase the humidity by placing wet pebbles or claydite in a deep tray and putting a pot with the plant on top of it.


Feed your indoor allamanda only during the growing season, once every 3 weeks. Both mineral complexes and organics are used. As for the concentration, it should be the same as indicated on the package by the manufacturer.


For a more lush flowering in deep fall, the bush is trimmed.

The stems are shortened by ½ the length, with the cut above the leaf node. During the active growth of the bush, weakened stems are cut out in a timely manner. Since the shoots of this plant are difficult to call powerful, they need support.

Transplanting Allamanda

Transplanting is done at the end of flowering in the spring months. Young shrubs grow very quickly, so they have to be transplanted regularly once a year.

As they get older, the frequency of transplants is reduced to one every 2 or 3 years, and they are only done when really needed.

There are 2 types of potting soil mixture suitable for growing Allamanda:

  • sod, leaf and mulch soil, peat (1:2:1:2) and also a small amount of sand;
  • leaf and sod soil, mulch, peat and sand (2:1:5:1:1).
  • Poisonousness of allamanda

    Remember that the sap of allamanda contains a strong poison. Because of this, be sure to wash your hands well with soap and water when you are finished working with the flower. For example, the sap of the plant can get on your hands during the propagation or transplanting procedure.

    Propagation methods

    Growing from seed

    A soil mixture of sand and peat (1:1) that must be moistened beforehand is used for sowing the seeds. Seeds are covered with a film on top and taken to a warm (23 to 24 degrees) place. Regularly arrange them airing, and if necessary, moisten the substrate with a sprayer. The first shoots should appear on the surface of the substrate 3-6 weeks after sowing.


    First of all, prepare cuttings.

    To do this, cut off the almost woody stems and divide them into sections of about ten centimeters in length. For rooting, they are planted in moistened sand. In order for rooting to occur quickly, the lower part of the cuttings is treated with a product that stimulates root growth, as well as provide bottom heating. The cuttings need systematic spraying as well as warmth (23 to 24 degrees).

    After complete rooting, the cuttings are transplanted into separate containers, using a substrate consisting of turf and humus soil and also sand, which are taken in equal parts.

    After 1-1.5 months, the plants are given the same care as an adult shrub.

    Possible problems

    Allamanda: home care, transplanting and propagation, species

    Allamanda rot

    Allamanda plants sometimes have a blackening of the stem base and then rotting on it. This is caused by stagnant moisture in the soil mixture or by overgrowth during planting. This can also lead to the development of black feet on the young plants.

    Allamanda leaves turn yellow

    Lack of nutrients or poor light leads to slower growth, shorter stems, fewer flowers and possibly yellow leaf blades.

    Allamanda leaves turn brown and curl

    The leaf plates turn brown and are also curled by exposure to cold air or a draft. Excessive moisture can also be the culprit. Reduce watering and monitor the room temperature.


    Allamanda is most often settled by pests such as: nematodes, spider mite, whitefly and aphids.
