What is the function of rosemary? 1. Clean the air.

Rosemary has a fragrant smell, which can purify the air and remove peculiar smell. Its leaves can absorb harmful gases such as dust, smoke and carbon dioxide in the air, thus improving air quality.

2, sterilization and insecticidal

There is a special essential oil in rosemary juice, which can kill bacteria and eggs, such as centipedes, spiders and other insects. When cleaning at home, you can use rosemary, which can not only sterilize, but also freshen the air.

3. Plenty of light

Rosemary is suitable for growing in full sunlight or semi-sunlight, which requires high illumination. Good light should be ensured during the growing period. If rosemary is kept in the shade for a long time, the plants will turn yellow and wither.

Step 4 water properly

Rosemary has strong drought tolerance and is suitable for growing in semi-dry soil. It is best to build a canopy for it in rainy season to avoid excessive water accumulation in the soil, but it is hot in summer and needs to be watered every 2-3 days.
