1、 Sunshine demand

Rosemary can be raised on the balcony. In the peak growing season, it needs to be exposed to enough light. If raised at home, the environment is too shady, which will lead to the plant growing in vain, and the branches and leaves become sparse and weak. If placed on the balcony and given sufficient light, it can improve the growth and promote the plant to be strong. However, the strong light in midsummer should not be directly irradiated, which may lead to plant weakness and weakness, and seriously affect the growth and development in the later stage

2、 Provide soil

It likes alkaline soil. In order to grow well, it needs to provide sandy soil with good drainage and contain certain nutrition. Do not use heavy and hardened soil, otherwise it will hinder the later growth

3、 Temperature range

When the temperature is kept at 20-30 ℃, it grows better in this range. It can withstand the cold climate and the temperature of minus 5 degrees, but the growth rate will slow down

4、 Apply fertilizer

Rosemary doesn't need much fertilizer. It can be applied three times a year. Fertilizer should be applied at seedling stage, mainly nitrogen fertilizer. During the vigorous growth period, it is also necessary to apply fertilizer once, which needs to be sufficient to meet the growth needs. At the end of autumn and the beginning of winter, a supplement of fertilizer can provide reserves for the arrival of winter
