Introduction to the cultivation technique of Spathiphyllum
A comprehensive introduction to the cultivation technique of Spathiphyllum, including its propagation methods and cultivation tips related to flowering plant cultivation. Let's take a look together.
Spathiphyllum, also known as Calla Lily or Guangdong Poison, has an elegant plant shape and bright green leaves. It is shade-tolerant and easy to manage, making it an excellent ornamental leaf plant. It is very suitable for decorating indoor gardens, large halls, and venues, and can also be used to decorate living rooms and studies. How to cultivate Spathiphyllum? Let's find out.
1. Growth Environment Requirements
Spathiphyllum is relatively easy to manage and simple to cultivate. Loose sandy soil is beneficial for the expansion of the corm, and it can also grow well in general vegetable garden soil or potting soil. Spathiphyllum prefers a warm environment, growing well at temperatures between 20-30 degrees Celsius. It is best to maintain temperatures above 5 degrees Celsius during the winter. Although temperatures below 5 degrees Celsius will not kill the plant, they can cause the leaves to turn yellow and lose their green color. It can grow well in a bright place without direct sunlight, especially in the hot summer months. However, allowing it to receive some direct sunlight during the winter can promote its growth. In a well-ventilated environment, the leaves of Spathiphyllum will be relatively smaller, so it is best to place it in an environment with poor air circulation.
2. Watering Method
Spathiphyllum is usually planted in potting soil with good water retention, drainage, and aeration. It is best to repot and change the soil once a year during the Spring Festival. In the summer, adequate shading should be provided, and watering should be sufficient to keep the potting soil slightly moist but not waterlogged, as积水 can cause stem rot. During the spring and autumn growing seasons, frequent watering is needed to keep the potting soil moist, while in the winter, slightly drier potting soil is preferable. The soil should not be too wet to avoid root rot. In addition to providing sufficient water and keeping the soil moist during the growing season, it is also necessary to frequently spray water mist to increase humidity and clean the leaves.
3. Fertilizing Method
Spathiphyllum requires relaxed management. During the spring and autumn growing seasons, a liquid fertilizer with a nitrogen-potassium base should be applied monthly, with a fertilizer concentration of about 15%-20%. This promotes lush growth. After entering winter, the plant should be moved to a sunny or semi-shaded indoor area, maintaining a suitable temperature above 5 degrees Celsius. Fertilization should be stopped during the winter. When repotting, a few pieces of horse hoof leaves can be placed at the bottom of the pot as a base fertilizer. During the vigorous growing season, a thin liquid fertilizer should be applied every half month, preferably using a fertilizer with more nitrogen.
4. Precautions
Spathiphyllum has a certain degree of shade tolerance, but to keep the leaves green, it is best to place it in a shaded area of the balcony or courtyard during the spring and autumn seasons, and move it to a well-ventilated area in the summer to avoid direct sunlight. Its optimal growth temperature is 20-25 degrees Celsius, and maintaining temperatures above 8 degrees Celsius during the winter is sufficient for safe overwintering. Low temperatures can cause frost damage. The sap of Spathiphyllum is toxic, which is the origin of its "Guangdong Poison" name. When planting, it should not be ingested or come into contact with the eyes, as it can be life-threatening in severe cases.
