Cultivation Techniques and Management Methods for Clivia

Clivia cultivation and management can be approached from the following aspects; only by mastering some basic knowledge of it will you be able to handle its care with ease.

1. Water:

Plant growth cannot be separated from water; the absorption of nutrients and all physiological activities must rely on water.

Clivia likes neutral or slightly acidic water, with a pH of around 6.5. In addition, we know that the pH of water varies from place to place. If the water is not neutral or slightly acidic, you should consider improving it; for example, alkaline water can be neutralized with rice-washing water. Clean water rich in minerals is best. Tap water has been treated with artificially added chemicals, so it should usually be stored for a few days before being used to water flowers. The water content in the soil should preferably be neither dry nor wet. Watering should follow the principle of not watering when not dry, and watering thoroughly when you do water. If the water content in the soil remains too high for a long time, the air permeability of the soil will worsen, causing root rot; conversely, if the water content is too low, it will cause dehydration, leading to shriveled and withered roots.

In addition, note that so-called dryness in watering does not mean there is no water, but rather that watering should be done only when the water content is relatively low. Watering is not suitable at midday when the temperature is too high; watering in the morning and evening is best. Also, watering should avoid the flower center, especially during the period when the scape emerges and it blooms, to prevent unclean water from causing heart rot.

2. Soil:

Clivia's roots are fleshy roots, suitable for growing in loose, fertile, well-draining, and well-aerated soil, so humus soil is the first choice for growing Clivia. The humus soil is best made from oak leaves (oak tree leaves). Other leaves such as larch, hazel, pear, and apple tree leaves can also be used, but attention should be paid to pesticide factors. Walnut tree leaves are toxic and cannot be used. High-quality humus soil should be moderately rotted tree leaves, with a decay degree of about 50%. In addition, the soil pH varies in different regions, so neutral or slightly acidic soil should be selected, with a pH between 6.5 and 7.

3. Light:

As the saying goes, all things grow by relying on the sun, so light is an indispensable element for any plant, and Clivia likewise needs sufficient sunlight, but it is not tolerant of strong light. In summer, shade treatment should be carried out under strong light to avoid sunburn on the leaves. Clivia leaves have strong phototropism; during cultivation, if the light-facing angle is adjusted regularly, the plant shape can grow neatly. Its leaves should be kept clean, and dust on the leaves should often be wiped off with a soft damp cloth, which is beneficial to photosynthesis.

4. Fertilizer:

Clivia is a flowering plant that loves fertilizer, so fertilizer is an essential and important nutrient source for its vigorous growth. Although it is a fertilizer-loving flower, fertilizer should still be applied in the right amount; too much or too little is unfavorable to the growth of Clivia. Too much will cause root burn, and the leaves will wrinkle or become stunted; too little will lead to a lack of nutrients, slow growth, and leaves that are noticeably narrower, softer, and not upright.

Fertilizers are divided into solid fertilizer and liquid fertilizer. Solid fertilizer: after castor seeds, hemp seeds, sunflower seeds, perilla seeds, etc. are stir-fried, adding a small amount of bone meal makes a very good solid fertilizer. Solid fertilizer is usually used as base fertilizer (bottom fertilizer and waist fertilizer), applied twice a year (spring, April-May; autumn, September-October), but it must not touch the roots, so as to avoid root burn.

Liquid fertilizer: after sesame, peanuts, hemp seeds, sunflower seeds, freshwater fish (with internal organs removed), etc. are fully fermented, they become a good liquid fertilizer. Liquid fertilizer is used as a supplementary fertilizer; its effect is quick, but its fertility is short-lived, so it can be applied once every half month. Liquid fertilizer should be applied according to the principle of low concentration and small amounts applied multiple times, to prevent excessive fertilizer from burning the roots. In spring and autumn, Clivia grows vigorously, so liquid fertilizer should be applied to provide sufficient nutrients. When applying liquid fertilizer, avoid dripping it onto the leaves or the heart of the plant, so as to prevent leaf rot or heart rot. After each fertilization, use a spray bottle to spray clean water to rinse the leaves or the heart of the plant.

5. Temperature:

Because Clivia is a semi-shade plant, the suitable temperature for its growth is 15°C to 25°C. In summer, when the temperature is above 25°C, methods such as ventilation and shading should be used to lower the temperature. Above 30°C with low humidity will cause the leaves to lose their luster; high temperature with abundant water will make the leaves grow too long; high temperature may even cause high-temperature disease, leading to the rot of the entire plant. Below 10°C, growth and development will be slow; below 5°C, growth will be inhibited; below 0°C, the leaves will freeze and be damaged or the plant will die.
