Lagerstr├Âmien, Lagerstroemia indica - Plant & Care

The Content Of The Article:

Camp tribes come from the Mediterranean and decorate many gardens or parks there. It thrives especially well in warm areas. Their flowers unfold from August to October. There is the Lagerstroemia indica in the colors pink, red, purple and white. It is 50 cm to about 2 m high.
For the Lagerstr├Âmie to develop its full beauty, it needs the right care. In summer, it should preferably be in a place facing south, which is also protected from the wind. When the growth of the plant starts, it needs suitable fertilizer and regular water. Apart from that, the care of Lagerstr├Âmie is rather uncomplicated. Nevertheless, it is important to avoid both waterlogging and complete dehydration of the earth. To preserve the beauty of the plant, it should be wintered before the frost.
Substrate & soil
Substrate and soil, in which the Lagerstr├Âmie feels comfortable, should be adapted to the needs of the plant. It thrives very well in normal garden soil or in potting soil. These should have a lime-free, slightly acidic pH or be neutral. Calcareous or alkaline soil is not suitable for the plant. As a substrate can also coarse sand, which is mixed with deposited compost and garden soil, serve.
The plant is fertilized normally, preferably at regular intervals of four weeks. It can be used conventional liquid fertilizer. However, the amount of fertilizer should in any case not exceed the recommendations of the manufacturer, as otherwise the dreaded "burns" may occur.
To cut
The Lagerstr├Âmie should be regularly lighted. It can be pruned in the spring when the first shoots show. Even in the fall, it may be cut back significantly around. A strong pruning is also possible and poses no problem for the plant. In addition, it can be put on a stick. Thereafter, however, it may be that the flower does not start again until the year after next. In addition, it is possible to cut off the thinnest shoots above the ground between December and January, but only at the time when all the leaves have fallen off. Thicker shoots are left longer and not quite as severely cut. If it is a high trunk, we recommend a radical cut, which should take back the entire crown.
Increase the Lagerstr├Âmie is straightforward, the cuttings of the plant rooted usually easily. Sowing of seeds should be done in summer. With appropriate maturity, however, it may also be possible in spring or late autumn. Only cuttings that have leaves but no flowers are propagated. They are cut off and then placed in a breeding box, which is heated. If the temperature of the soil is constant at 25┬░ C, it comes within a few weeks to a sufficient development of new roots. Once these are strong enough, they can be repotted. Their care then takes place in the same way as that of the mother plant.
Since the Lagerstroemia indica, like all species of the Mediterranean, are not hardy, it is important to protect them from the first frost. As a rule, only older plants with mature wood can withstand temperatures of up to -10┬░ C for a short time only. For example, the camp river grows on the island of Mainau as a bush, which is equipped with good winter protection. In addition, it blooms only after sunny and warm summer months. For hibernation, the plant is housed in the unheated cellar. Even in a garage feels good during the winter months. The temperatures are ideally at +5┬░ C. The camp stream loves a dark location during hibernation as it throws leaves. During this time, the plant should be poured only moderately. However, it must never dry out or be fertilized.
The Lagerstr├Âmie should be relocated as soon as possible to a light and warm location. The month of February is well suited for this. When she stands at a southern window in the full sun, she feels most comfortable. If she drives out the first leaves, she may be fertilized again and poured a little more. On cloudy, darker days, the leaves are hardened. Incidentally, this also succeeds if it is dwarfed for a few days, otherwise their leaves could burn. The room where the camp stream winters should also be aired regularly, but only on frost-free days.
Lagerstroemia indica should rarely be repotted, if possible. Especially not before the bloom subsides. The right time for this is in the spring, before the first shoots show up. As a rule, that...

  • Young plants may be repotted every two years
  • older camp streams are only repotted every four years
to water
In general, the Lagerstr├Âmie should be watered regularly, but it must not be drowned. On the other hand, it must not dry out. Tip: So that the bearing flow does not get too much water, it should always be poured only when the top layer of the earth has dried through. This is especially good with the thumb sample. Water that has overflowed should be removed immediately.
In summer, the camp stream needs a sunny spot in a southerly position, both in the garden and on the balcony or the terrace. After the buds form in June to July, they also tolerate a place outdoors. When the plant starts to grow, it is fertilized regularly every fourteen days. The casting should now be adapted to their needs. The care is not complicated, because the Lagerstr├Âmie must be poured only twice a week.
Diseases / pests
The Lagerstr├Âmie often suffers from aphids, of which it is attacked. In addition, powdery mildew or gray mold is one of the diseases that can affect them. If the Lagerstroemia indica sheds its leaves, a strong pruning is usually required, because only then all diseased parts of the plant are removed. Powdery mildew occurs when the leaves of the camp stream were too wet for a long time. However, an open and draughty outdoor location creates a perfect starting point to prevent powdery mildew. If the plant is protected by a glass, it can not come to infestation, since the leaves are not sprayed when pouring.
Frequently asked questions
  • Why does not Lagerstr├Âmie flourish? - If the pruning of the plant has taken place radically, it may be possible that the flowers stop for one year and reappear only the year after next. However, this is perfectly normal and no cause for concern.
  • Is the need for light particularly high during the hibernation? - No, because the Lagerstr├Âmie does not have leaves from the autumn months, so that the light requirement is not very high. It can therefore be placed in a rather dark location for wintering.
  • What can be done to protect the plant from mildew? - An airy place with a light breeze, reliably prevents powdery mildew. There, the leaves dry faster after rainfall.
Worth knowing about bearing currents soon
From the belonging to the family of the Weiderichgew├Ąchse Lagerstroemia there are now numerous breeds, some are hybrids. The best-known Lagerstroemia species include:
  • Lagerstroemia indica
Lagerstroemia indica is especially characterized by its frost hardiness down to -18┬░ C. However, it may happen that the shoot tips freeze, so that after the winter, a strong pruning is necessary. The white, pink, red or violet appearing flower spikes up to 45 cm long. With the outdoor stand, a Lagerstroemia indica grows to a tree that grows more than 3 m tall.
  • Lagerstroemia speciosa
This species is native to the tropical wetlands of India, southern China and the Philippines. It is often referred to as a queen flower. It tolerates no frost, but stands out with its particularly lush flowering of other Lagerstroemia species.
  • Lagerstroemia fauriei
This species is characterized by a high resistance to mildew. In addition, Lagerstroemia fauriei also tolerates somewhat severe frost, making it particularly suitable for year-round outdoor culture.
  • Lagerstroemia floribunda
Not winter-proof is the Thai-origin variety Lagerstroemia floribunda with pink flowers. The leaves are decorated with showy bright mid-ribs and the inflorescences have particularly many branches.
  • Watering is best done on all Lagerstroemia species whenever the soil is slightly dry.
  • Over the summer, fertilizers provide the plants with the vital nutrients every 3-4 weeks.
  • Spider mites can settle on pests on the plants. They are recognizable by their fine webs.
Tip: vigorous showering and the subsequent treatment with appropriate spraying in compliance with the manufacturer's recommendation brings as a countermeasure certainly the best success.
To cut
  • If the non-winter-proof Lagerstroemia species are brought into the house in autumn, the first pruning can already be done.
  • Ideally, Lagerstroemia plants are cut in spring. Since the flowers sit on 1-year-old shoots, the pruning may be strong.
  • On this occasion, the shrub should also be lighted regularly so that the flower spikes have more space for their development.
  • The winter-proof Lagerstroemia species can stay outdoors during the winter.
  • A protection from the cold in the form of mulched leaves and piled up branches prevents the worst frost.
  • Non-frost resistant plants need a wintering place with an average temperature of 10┬░ C.
  • Since all Lagerstroemia species shed their leaves anyway, brightness in the wintering quarter is not absolutely necessary.
  • The casting should be throttled so that the root ball constantly remains only slightly moist.
