Botrytis has not high requirements for substrate, because its root is very developed, and generally it will occupy the whole flowerpot. It can be made of peat soil, water moss, perlite and other materials, and can pad some broken basin pieces at the bottom of the basin, which is conducive to ventilation and light transmission. For soil, poor acid soil is best.

The best growth temperature is 20 ℃ - 32 ℃, and the temperature should not be lower than 5 ℃ when entering dormancy period in winter. Summer to avoid high temperature, remember to properly shade, and strengthen ventilation, for it to create a comfortable environment, and do not put it on the bare concrete, after exposure to the sun is likely to burn
Botrytis is suitable for growing in a humid environment, not resistant to drying, and the air humidity is better to be kept above 30%. In the growing season, it's better to plant by pot leaching to keep the humidity of the substrate. In summer, it's better to spray more water on the leaves to keep the environment moist, and it's also good for cooling.
Botrytis is resistant to the sun. It needs sufficient light for its growth. Only when the light is insufficient, the color will be monotonous. But in summer, we should pay attention to shade and avoid direct sunlight. Otherwise, too strong sunlight may burn the blade barrel. Winter dormancy period can reduce the light, but it is necessary to pay attention to Oh, do not grow in the dark conditions of the bottle grass suddenly exposed to the sun, is likely to cause death because of inadaptability.

The potting soil needs to be kept moist. It is better to use rainwater for watering. Water several times in summer, but the water temperature should not be too high. Water should be controlled in winter, and the soil should be slightly wet. Be careful when watering. Don't pour water into a bug catching bottle, and there should be no water in the bottle.
In spring, nitrogen fertilizer can be applied once every half a month, and 0.2% - 0.3% liquid fertilizer can be used for root irrigation. However, it is not always necessary to apply nitrogen alone. The red leaf of Sargassum is best applied with nitrogen, phosphorus and potassium. In winter, we will stop fertilizing.

This is how to raise the bottle grass introduced by Xiaobian. I hope you can cultivate healthy and colorful bottle grass.
