How to grow rainbow arrowroot

1. Maintenance methods

1. Temperature: Rainbow arrowroot has relatively high requirements for temperature. Generally speaking, the most suitable range is between 18 and 25 degrees. It is a plant that is neither tolerant to high temperatures nor cold weather. Therefore, the high temperature should not exceed 30 degrees, and the low temperature should not be lower than 10 degrees. This is more beneficial to its growth and health.

2. Light: Rainbow arrowroot likes light, but it is also afraid of excessive sunlight. Therefore, astigmatism is the most suitable for it. Generally speaking, when the light is relatively mild, it is sufficient to provide full sun, so that its leaves will be more vigorous and more ornamental. When there is strong light, pay attention to shade.

3. Watering: Rainbow arrowroot likes moisture and is very afraid of drought. Therefore, do not wait until the substrate has been dry for a long time before watering. You need to add water when it is semi-dry. Just water it thoroughly, but don't let too much water accumulate.

4. Fertilization: Rainbow arrowroot has a relatively high demand for fertilizer. Generally speaking, it should be applied once a week when growth is rapid. However, the concentration should not be too high.

2. Breeding techniques

1. Reproduction: It can be propagated by division. It is better in spring. When operating, you must first choose a strong plant as the mother plant. Take it out of the pot and separate it, making sure each part has at least three to four leaves. After planting, water thoroughly and place in semi-shaded location. Generally speaking, for a plant that grows very vigorously, it is more appropriate to divide it every two years.

2. Repotting: Breeding and repotting can be done at the same time, and it is more suitable in spring. Specifically, you can choose humus soil, river sand, and add an appropriate amount of compost. It is best to repot the plant once every two years or so, and do not leave it that way for too long.

3. Problem diagnosis and treatment

1. Diseases: Generally speaking, it does not have too many diseases and pests, but they are common only when the climatic conditions are very unfavorable. For example, "rust" and so on. It can be treated with carbendazim.

2. Pests: Common ones include aphids, whiteflies, etc. They can be killed with an emulsion of anthracene.

IV. Other issues

1. Toxicity: Rainbow arrowroot is not poisonous, and its leaves have the ability to absorb harmful substances.

2. Can it be raised at home: Very suitable. Because it is essentially a foliage plant, it is very common to place it in potted plants at home.
