The Content Of The Article:
The piston thread is a houseplant, which has narrow to oval, long leaves with a white, silver or light green stained drawing. The height of this plant usually remains below one meter and is about 30 to 100 cm.
In late summer or autumn, the bulbous thread forms a yellow or white flower, which encloses a white bulb. When the flower has flowered, orange, yellow or red berries form. All parts of this plant are toxic to both humans and animals due to saponins and hydrogen cyanide in the sap. If the plant is touched, it can cause inflammation and redness on the skin. When ingested, it can cause swelling and burning on the lips, throat and tongue. But also inflamed oral mucosa, internal bleeding and arrhythmia can be the result of poisoning.
Location of the piston thread
The piston thread should be placed in a bright, warm location with high humidity. Ideally, this is more than 50%. It is important to ensure that the plant does not get draft. The houseplant should never be exposed to direct sunlight as it will not tolerate it. Some species, especially the monochrome, need less light and can be accommodated in a more shady place. The temperature must never fall below 18° C even in winter.
In summer, the houseplant likes a temperature of about 20 to 25° C. To prevent the piston thread on the sill from becoming too cold, cork pads can be placed underneath. The bathroom is particularly suitable as a location, as there is usually a higher humidity. Furthermore, it makes sense to spray the leaves regularly with water and to put the plant on a filled with gravel and water container. This ensures a higher humidity. This also works great with a commercial humidifier.
Care of the piston thread
In summer, the piston thread should be regularly poured with lukewarm, lime-poor water. In winter, the plant requires significantly less water and should therefore be poured only moderately. A cut of the crop is not necessary. The quite undemanding house plants can be planted in normal potting soil. To loosen up some perlite can be added to the soil. A mixture of peat and compost leaves the plants thrive well. The optimal pot diameter is about 10 to 15 cm. Young plants should get a bigger pot every spring. Older plants are only repotted every two to three years.
Since the roots are sensitive to salt, only a sparing fertilization with liquid green plant fertilizer should be done every two weeks. Half the recommended concentration on the package is used. The piston thread feels the best in the company of other plants and thrives all the better. It is therefore recommended to plant it together with other plants.
Diseases, pests and application errors
Lice, which feel very well on the plant when the air humidity is too low, can be dangerous to the piston thread. A mixture of soap and spirit can dispel the harmful inhabitants. Spider mites also like to colonize the plant. These can be rinsed off with a jet of water. However, if the plant has very dense leaves, a pest infestation is often noticed too late and can not be repaired with water. In this case, you usually need to resort to stronger pesticides. When temperatures are too low, direct sunlight or calcareous water, brown leaf margins or rolled leaves are not uncommon. Withering the leaves, this is a sign of dryness or too much water. Waterlogging is essential to avoid, as the roots can easily rot in this case.
Multiply piston thread
After some time, the houseplant is less handsome than in younger years. Therefore, it should be redrawn about every three years. A simple way to increase the piston thread is the division. In this case, the root ball, preferably in the spring during repotting, separated into several parts. It should be ensured that each part has at least three leaves. After planting in a mixture of sand and peat, the pot should be covered with plastic. This is z. B. a garbage or freezer bag.
In a bright location, the young plants usually grow well within six to eight weeks. Also possible is the replacement of offshoots, which are formed in the summer on the mother plant. The following spring, these branches are separated and planted in pots.

Worth knowing about the piston thread soon
- The bulb belongs to the family of the arum family and like this it is poisonous and that in all plant parts. Especially through the sap can cause skin irritation.
- The piston thread is a fairly undemanding houseplant. However, she likes it warm and humid. That's why she thrives especially well in bathrooms with windows, though she does not need it bright.
- The bulbous thread flowers and bears fruit, but is mainly cultivated for its beautiful leaves. Ideally, the plant is placed in a hydraulic vessel. So you have the least amount of work and the humidity is not such a problem.
- The location should be warm, never below 18 degrees. Light is not needed much. The monochrome species tolerate the most shade. The colorful varieties need more light.
- As Pflanzsubstart is normal potting soil, if it is always kept evenly moist. Better is hydroponics.
- Repotting is done in spring, about every two to three years. The pots should be rather wide than high.
- Propagation can be done by division, by propagation of cuttings and by sowing.
- As pests, lice often occur. This is usually due to low humidity. Especially wool lice then settle on.
- Spider mites occur again and again. In both pests timely control is important so they can not spread.
