Rosemary, a plant that can be raised on a balcony, needs to be exposed to enough light during the peak growing season. If raised at home, the environment is too shady, it will lead to the plants grow in vain, the branches and leaves become sparse and weak, and put on the balcony to give sufficient light, which can make the growth better and promote the plants robust. However, the strong light in midsummer period can not be directly irradiated, which may lead to plant weakness and weakness, seriously affecting the later growth and development.
It likes the alkaline soil. In order to grow well, it needs to provide sandy soil with good drainage, but also contains certain nutrients. Do not use the clay heavy and hard soil, otherwise it will hinder the later growth.
When the temperature is kept at 20-30 ℃, it grows well in this range. Cold weather can withstand, 5 degrees below the temperature can also withstand, but the growth rate will slow down.
Rosemary does not need much fertilizer. It can be applied three times a year. Fertilizer should be applied in seedling stage, mainly nitrogen fertilizer. In the period of vigorous growth, it is necessary to apply fertilizer once more to meet the growth demand. At the end of autumn and the beginning of winter, a supplement of fertilizer can provide reserves for the coming of winter.
