Ease of cultivation Oppenheimer’s opener is easy enough to grow the plant, other species are a little more difficult to care for.
The size Not a very large plant up to 90 cm in height and width.
Growth rate 5-6 new leaves per year
Lifespan Perennial.
Temperature In summer: 71,6-77 ° F, higher temperatures require high humidity. In winter, not lower than 60,8-64,4 ° F. The plant does not like sudden temperature changes.
Humidity Not less than 60%. In summer and winter, spray at least 3 times a week, and preferably every day with soft water, the pot must be placed in a tray with wet pebbles. Especially dangerous is the low humidity in winter, which should be increased by all known  ways.
Lighting The bright diffused light, penumbra, it is better to put in 0,5 m from a bright window. On the southern window is necessarily good shade. The north and west window will do.With excessive light, the leaves twist, their color fades. More shade-tolerant plants with monotonously colored leaves.
The soil The soil must be breathable, sand or perlite with peat should be added if it is too dense. For a mixture of self-cooking should take: 1 part leaf soil, 1 part humus earth, 1/2 part of sod land, 1 part coarse sand or perlite and 1 part peat. Good drainage is required.
Watering Soil must be constantly moist, in summer it should be watered every 4 days. Use warm soft water. With insufficient watering, the leaves begin to twist and dry up. In winter, watering is limited to 1 time per week, when the leaves begin to form, the soil must dry between two waterings. You can not allow water to stagnate in the pot and water on the leaves, which can form spots.
Fertilizer During the growing season, every 15-20 days with a liquid fertilizer, diluted twice. The cesspool is not well tolerated by stagnation of calcium and nitrogen in the soil.
Reproduction Late spring division by transplantation, trying not to damage the roots of the plant. In some species, at the ends of the shoots, leaf sockets arise, which easily take root. You can propagate with stem cuttings, which are cut with a piece of rhizome at 1.5-2 cm under the knot. It is desirable to cut the leaf plate or twist it into a tube to reduce evaporation. Put the cherry in water or in peat with sand and cover with polyethylene.
Bloom Blooms in the summer with white, nondescript small flowers in spikelets.
Transfer In the second half of spring, young plants should be transplanted annually, the pot must be shallow, since the root system is superficial. In the future, transplanted every 3-5 years, as soon as the roots appear from the drainage hole. When transplanting, the plant can be divided.
Features of care The leaves of the plant, like all members of the family, are formed at night – this is normal. In summer, the plant can be taken out to the garden or to the balcony, but it should be protected from the wind. The plant does not like draft gas and combustion products. Completely dried leaves should be removed in a timely manner. Wipe the leaves with either a soft dry cloth or a brush, since they are easily damaged. The plant has old, near-to-center parts of the rhizome dying off. Therefore, the plant should be periodically divided.
Difficulties Leaves wilt and wrinkled with a lack of moisture in the air. Sheet plate wilt and wilts as a result of drying the soil or overheating the leaves. The leaves become sluggish and rot when the temperature is too low or the temperature drops sharply, especially if there is excessive watering and insufficient sunlight. When the air is dry, the tips of the leaves turn brown and dry out. On the leaves, white and yellow spots are a sign of a salty burn. On the leaves, dark spots appear as a result of overmoistening. Lack of light is manifested in the fact that the plant tends towards the window, the plates of young leaves become shorter and narrower than those previously formed. It is affected by a spider mite, mealybugs, scutes.
