Stripe 12 roll has strong drought resistance and can grow well in dry environment, but this does not mean that it does not need watering and fertilization. Because the root system is afraid of water stains, if there is too much water or fertilizer in the basin, it is easy to rot.
Therefore, watering and fertilization should adhere to: between dry and wet, dry to dry, not dry, dry to water.
Water the next day after fertilization to promote the absorption of fertilizer effect. Avoid wetting the plants when watering.
The most suitable temperature for the growth of twelve rolls of stripes is 15-32 ℃. If the temperature is over 33 ℃ in summer, it will enter the dormancy period.
The overwintering temperature should be controlled above 10 ℃. If the winter temperature drops to 7 ℃, it will enter the dormancy state. If the environment is close to 4 ℃, the plants will be frostbitten and die.
In spring and autumn, the temperature is not very high. Twelve rolls of stripes are in the growing season, which can give direct sunlight. Photosynthesis can promote the accumulation of nutrients.
In summer, the plant should be kept in the half shade, or put in the outdoor shade for 50%, the leaf color will be more beautiful.
In winter, put it in a bright room for maintenance, pay attention to temperature control, and often rotate the direction of the flowerpot to make the plant receive light evenly.
Stripe twelve like relatively dry environment, continuous rainy days are easy to infect pests.
Do not forget to spray water on the leaves at night to keep the leaves dry.
The most suitable air humidity is 40-60%. When the humidity is not enough, it can be humidified by sprinkling water and spraying water.
The method of dividing plants can be combined with basin changing. It can be carried out all year round. When the pots are changed from April to may, the young plants around the mother plant are peeled off and potted directly. After the ramets are potted, they should be placed in shade and watered under control. After the new roots grow, the light and water amount should be increased gradually. The basin soil should be a mixture of 2 parts of saprophytic soil and 1 part of river sand, in addition, a proper amount of bone meal or superphosphate should be added as the base fertilizer. Every spring and autumn is the vigorous growth period, and the watering should be appropriate. The pot soil should be dry, too much is easy to cause root rot. at this time, the fertilizer demand is large, and the compound fertilizer is usually applied once every three weeks; the summer is the dormancy period, control the watering, and pay attention to the appropriate shade; the temperature in winter should be maintained above 10 ℃, and the watering amount should be dry. The low temperature and large watering amount will cause leaf wilting and planting. Plant death.
Cuttage: from May to June, the fleshy leaves were gently cut off, with the upper half of the lignified part at the base, and inserted in the sand bed, about 20-25 days could take root. When the root length is 2-3cm, it can be potted.
The stripes placed in the indoor culture are 12 volumes. Try to put them near the doors and windows in the southeast direction, so that they can receive sunlight. And every half month or a month, move them to the outdoor culture for a period of time. Even if the sunlight is sufficient indoors for a long time, the leaves will become thinner, and the new branches and petioles will be slender.
The root system with 12 rolls of stripes is very sensitive and afraid of water stains. If there is water in the flowerpot, or the watering and fertilization are too frequent, it is easy to rot the root, so the watering should be well controlled.
When the twelve rolls of stripes enter the dormancy period, the number of water and fertilizer should be controlled. When watering, try to choose the time when the temperature is high at noon on a sunny day.
