Insufficient light: the walls around the house are blocked, so the sunlight can't penetrate in, and it can't provide the sunlight needed for the growth of Acorus calamus. If it is left at home for a long time, it will cause the leaves of Acorus calamus to wilt and yellow.

Poor ventilation: the doors and windows in the home are closed, and the air circulation is small, so it is difficult for Acorus calamus to breathe fresh air. When breeding, it can be placed outdoors to let the branches and leaves be blown by the breeze, so as to prevent Acorus calamus from being infected with diseases such as root rot and leaf spot.

Matters needing attention in raising calamus

1, illumination: Only by ensuring sufficient illumination can it grow more healthily, and family maintenance needs to see the sun for about 3 hours every day. The sun is strong in midsummer or early autumn, so it needs to be moved to a cool place.

2, moisture: it likes to be wet very much. Usually, in addition to watering more, it should be properly sprayed with water. Pot soil needs to be in a wet state, and when the weather is dry, open more windows and sprinkle more water. When watering, water it evenly, preferably along the circle of the flowerpot.
