How to care for calamus in winter

Is calamus afraid of cold?

The most suitable growth temperature for calamus is 20-25℃. It is afraid of freezing and will generally stop growing below 10℃. Before the temperature drops in winter, you need to take measures to keep warm. Therefore, after the temperature drops, you can directly move the calamus indoors for maintenance, control the indoor temperature, and expose it to more sunlight.

How to care for calamus in winter

In winter, it must be moved to a warm and sunny room. The indoor temperature needs to be above 10 degrees. It should be exposed to the sun every day and can get full sun. The growth rate of calamus is very slow in winter and its demand for water and fertilizer is very small. You can reduce watering, keep the potting soil in a dry state, and reduce fertilization.

1. Antifreeze and keep warm

When the temperature drops in winter, the calamus needs to be moved indoors for maintenance in time. The indoor temperature needs to be controlled above 10 degrees. If you use heating or air conditioning at home, you cannot place it in the vent, as the plant will easily dry out.

2. Watering and replenishing water

In winter, calamus has a very low demand for water. Just keep the soil slightly moist and water it when the soil is completely dry. Because of the heating indoors, the air will be very dry. At this time, you can spray water in moderation to maintain humidity. The watering time should be at noon.

3. Prune dead leaves

The temperature is low in winter, and the branches and leaves of calamus easily turn yellow and fall into the soil, where they will rot and affect the growth of the plant. Therefore, it is necessary to prune the withered and diseased branches in time to promote the sprouting of new branches.

4. Proper lighting

Acorus prefers an environment with plenty of sunlight. If it is kept indoors, it needs to be placed on a sunny balcony. When the outdoor temperature is high and there is plenty of light, it can be moved outdoors to get more sun, or even full sun, to promote photosynthesis.

Precautions for breeding calamus in winter

1. Avoid freezing damage

Acorus will stop growing when the temperature is below 10℃, and will be frostbitten or even frozen to death when the temperature drops to around 0℃. Therefore, it must be moved indoors for maintenance in areas where it snows and freezes in winter. If there is no indoor heating, the room will freeze, so you must pay attention to keeping warm.

2. Do not place it in a cool place for a long time

If you care for calamus indoors, do not place it in a shady place where there is no sunlight, such as a desk, coffee table, or chopping board. Although it likes coolness, it cannot be away from sunlight for a long time. It should be placed in a sunny place indoors frequently to bask in the sun. At noon on a warm sunny day, you can also place it outdoors to receive direct sunlight.

3. Do not keep the soil too wet for a long time

Although calamus does not like a dry environment, due to the low temperature in winter, slow evaporation and poor indoor air circulation, if you water it too much, it will easily make the potting soil too wet for a long time, causing difficulty in breathing for the calamus roots, and in severe cases, the roots will rot. Therefore, you should water it in moderation and only water it when you find the surface of the potting soil is dry.

4. Don’t trim too hard

Winter is the dormant period of calamus, and no new leaves will grow. If you cut it too hard or too much, it will easily cause damage to it, which is not conducive to safe wintering. A more desirable approach is not to rush to cut off the entire leaf when you find yellow leaves and dry tips, but just trim off the withered and yellow parts.
