Cultivation methods and precautions of yellow bract arrowroot

1. Maintenance methods

1. Temperature: Caladium grows well under high temperatures, which can be seen from its origin. Generally speaking, it will grow better if the temperature is kept between 25 and 30 degrees. In addition, its cold resistance is very poor, so it is safer to keep the temperature above 15 degrees. If the temperature is below thirteen degrees, it may freeze.

2. Light: The yellow-bracted arrowroot prefers a semi-shaded environment and is afraid of direct sunlight. Strong light can cause its leaves to curl and dry up, so it needs to be properly shaded when the light is strong. But be careful not to keep it in complete darkness, because it still needs a certain amount of sunlight to grow.

3. Watering: Caladium likes moisture but is afraid of waterlogging. Therefore, sufficient water needs to be provided during the growth period, but water should not accumulate. Then there is the air humidity. In summer, try to spray more water to make the leaves look more moisturized.

4. Fertilization: Phosphorus fertilizer and potassium fertilizer are relatively the most important. It can be applied once every half a month, liquid fertilizer can be used, and the concentration needs to be strictly controlled.

2. Breeding techniques

1. Reproduction: It can be carried out by division. Generally speaking, it is done when the weather is warm, such as around May, otherwise the wounds will be difficult to recover after division. When dividing the plant, it is important to note that each part cannot be too small, and must have sufficient strong roots and an appropriate amount of leaves. The planting depth must also be strictly controlled and not too deep, otherwise it will affect the growth.

2. Repotting: Try to do it every one or two years. When propagating by division, it can be done together and replaced in spring. Specifically, the soil used can be a mixture of peat soil, leaf mold, and an appropriate amount of coarse sand. Note: alkaline soil cannot be used.

3. Problem diagnosis and treatment

1. Disease: Too much watering will cause "root rot", and the roots need to be removed from the pot and trimmed. Then there is "white rot", which is also caused by excessive watering and is prone to occur in July and August. Available sterilizing agents.

2. Pests: Mainly "scale insects" and "red spiders", which reproduce very quickly. In addition to normal spraying, you can also spray water to inhibit their reproduction.
