(1) soil: the main requirements are good drainage and air permeability, as well as weak acid. Specifically, we can use saprophytic soil and sandy soil, evenly mixed as culture soil.
(2) temperature: it's warm to root in the ground, so it's suitable at about 20 ℃. Winter must pay attention to, not less than zero, or will be frostbitten.
(3) watering: plants like to be wet. Therefore, especially during the growing period, it is necessary to provide sufficient water to make the basin soil in a moist state. But it is also afraid of waterlogging, there must be no water. In autumn and winter, you can reduce the frequency of watering. However, it may bloom in winter and need a little water.
(4) fertilization: mainly in the growing season, once a month.
Diseases and insect pests are more common, such as "powdery mildew" and other common pests. For disease can be treated with methyl tobujin; insect pest can be treated with oxidized dimethoate emulsion.
Can change basin once a year, change part of old soil, prune root, cut off rotten root. If you need it, you can change it into a bigger basin.
The most commonly used are cutting and sowing. Cutting mainly in May and June, with eight to ten cm long branches, pay attention to keep humidity. It is not suitable to cover the soil because the seeds are small. After sowing, if the condition is suitable, it will germinate in about half a month.
