Home care for pyaranthus
Needs bright, yet diffuse light. In winter and fall, it can be exposed to direct sunlight, but in summer, the plant should be shaded from it to prevent burns on the leaves.
In spring and summer, the pyaranthus needs warmth (22 to 26 degrees). In the fall, the temperature should be lowered. During the winter there is a dormancy period. At this time, the succulent needs a cool temperature of 14 to 16 degrees. Make sure that the room where the plant is located is not colder than 12 degrees.
Feel well at low humidity. There is no need to moisten from a sprayer.
How to water
Spring and summer watering should be moderate. Water after the top layer of substrate has dried. With the onset of the fall period, water the pyaranthus less.
During the winter, watering should be sparing, but the ground lump should not dry out completely (because of this, the shoots begin to shrivel). The cooler the winter, the less often watering.
Feeding is done from March to August 2 times a month. Succulent and cactus fertilizer is good for this.
Repotting is done in the springtime.
Young plants should be transplanted every year and mature plants every 2 or 3 years. To prepare the mixture, combine 1 part coarse sand with 2 parts sod soil. Commercially available soil for succulents and cacti is also suitable. A suitable container should be low. A good drainage layer should be made at the bottom.
Propagation can be by bush division, cuttings and seeds.
Cuttings should be made from old stems. They should be dried for 5-7 days at normal room temperature. After that, they should be planted in a substrate consisting of coarse sand with the addition of not very large amounts of peat crumbs. The cuttings will give roots after a little time.
Then it is transplanted into a small (7-8 centimeters in diameter) pot.
When growing at home the seeds are set quite easily, and they mature for about 12 months. The seeds are sown in a low, small container filled with sandy, light soil. If the seeds are fresh, the first sprouts will appear in 3 or 4 weeks. After picking the plants are planted in pots, the height of which should be 6 centimeters.
After 12 months, the piaranthuses are transferred to pots 8-10 centimeters
