Ornamental arrowroot is very personal, its leaves on the markings are different, the shape of the leaves is also different, they are most afraid of cold, winter there is no warm environment, it is not recommended to buy this plant, the lowest temperature to keep above 7 degrees.
In addition to avoiding frost, it is also necessary to pay attention to avoid curling and shrinking leaves, once the leaves continue to curl, the leaves will slowly hang low and wilt, and eventually cause the whole plant to wither or rot.

There are many reasons why ornamental arrowroot leaves curl, generally due to improper watering, stuffy roots, or infection with pests and diseases.
1. Improper watering
For example, insufficient watering and not watering thoroughly will cause the leaves of ornamental arrowroot to curl. Especially in places with heating in the north, the potting soil of ornamental bamboo leaves dries particularly quickly, and does not replenish water in time, or only sprays the surface of the potting soil when watering, and the soil is still relatively dry underneath, which is easy to cause the leaves to curl.
Or the soil is completely dry, it is difficult to absorb water, the root system is overgrown with potting soil, and the pot is not changed in time, which will lead to the soil not retaining water. These conditions can lead to a lack of water in the soil or plant root system, which can easily lead to leaf curling.
If there is a lack of water and the leaves are curled, you can soak the potted plants in clean water for about 10 minutes, and then pick them up to drain the water, and use the method of soaking the pot to replenish water to ensure watering, or you can use clean water for many times to slowly water through.
Ornamental arrowroot is also very afraid of more water, if you find that the leaves are curly, first check the dryness and wetness of the potting soil, if the soil is still relatively moist underneath, but the leaves still appear curled, it may be that the soil is stuffy. If this happens for a long time, it may rot roots.
2. Dry air

Ornamental arrowroot prefer a high humidity environment, and if the air is particularly dry, it will cause the leaves to curl. The vast majority of ornamental arrowroot prefer a relative humidity of more than 50%. If you raise oil painting arrowroot, it is necessary to maintain more than 80% air humidity.

If you maintain potted ornamental arrowroot with an ambient humidity below 50% for a long time, its leaf tips and edges will slowly dry out and yellow, and the leaves will slowly curl and will not wither all at once.
You can turn on the humidifier next to it, or put a basin of clean water at the bottom of the potted plant, put some relatively large stones, and put the potted plant on top of the stone.
3. Infected with red spiders
Once the leaves of ornamental arrowroot are found to be curly, the first thing to check is whether there are infected pests, especially red spiders, you can first check the back of the leaves, if the leaves become very rough, there are yellow-brown spots on the leaf surface and on the back of the leaf, and even small spider webs, then it must be infected with red spiders.
After infection with red spiders, yellow spots will appear on the leaf surface of ornamental bamboo leaves, that is, the sap of the leaves is absorbed by the red spiders, and the plant will gradually turn yellow and curly, and the red spiders should be removed in time after they are found.
If the environment is better, you can often spray water on the foliar surface (moisture should volatilize in time), and also improve humidity and increase ventilation. If it is troublesome, you can directly spray acaricide every two or three days, preferably two or three acaricides alternately, such as ethoxazole and avermectin.
4. The light is too strong
Ornamental arrowroot are more shade-tolerant, but they also like more scattered light, like soft scattered light, and are afraid of strong direct light.
If the light is too strong, their leaves will be damaged, the leaves will be dehydrated and dry, the leaves will also curl, the tips and edges of the leaves, will turn brown, this time to move the potted ornamental arrowroot to a place with less sunlight, you can give morning or evening light.
5. Extreme temperature
If the weather has changed particularly recently, the temperature has plummeted, or the temperature is too high, it will cause the leaves to curl (above 40 degrees).

Ornamental arrowroot can be moved to a place where the temperature change is relatively low, avoid sudden changes in temperature and humidity, and do not keep it next to cold wind or heating.
6. Water quality or fertilizer problems
Maintenance of potted ornamental arrowroot to avoid giving too concentrated fertilizer, if it is kept indoors, the temperature can be kept at 18~28 degrees, the maintenance position has appropriate light, you can give fertilizer every two or three weeks, the concentration is twice as low as usual.

If fertilization is too concentrated or too frequent, will it also cause the leaves to curl. If the situation is too serious, it is necessary to depot the plant, remove the soil, rinse it and re-pot it with new potting soil. When the situation is not too serious, rinse the potting soil with clean water several times.
Also pay attention to avoid alkaline soil, if you directly use tap water for a long time, or in places where the water quality is not very good, it is easy to lead to excessive mineral deposition, resulting in curly and wilted leaves.
