Clivia home cultivation methods include using soil, fertilizing, watering, heat preservation, lighting, etc.
1. Use soil
The native place of Clivia is under the big trees in the forests at high altitudes in southern Africa. Its roots are rooted in the layer of rotten leaves accumulated over the years. Clivia should be raised in loose and fertile neutral or weakly acidic humus soil. The cultivation soil can be a mixture of 65% humus soil, 20% clean sand, and 15% fine furnace ash. The relative humidity of the soil should be around 40%. If the soil is compacted and drainage is poor, it will lead to root rot.
2. Fertilization
For Clivia, solid fertilizer should be applied once in winter, less nitrogen fertilizer and more phosphorus and potassium fertilizer. Eggshell powder and cooked fish water are good phosphate fertilizers, and bran ash and soot are easily available potash fertilizers. Nitrogen, phosphorus, and potassium compound fertilizers can also be applied to promote the germination of more new plants and leaves. Fertilizer must be applied in an appropriate amount. Do not apply concentrated fertilizer or raw fertilizer that has not been fermented and decomposed. Otherwise, it will easily cause the leaf tips to wither or rot.
3. Watering
The soil should not be too dry or too wet. It must be watered thoroughly every time, and more after budding. Every 20 days or so, fermented bean cake water, light fishy water, horseshoe water, etc. can be combined with watering to combine watering and fertilization. When the room temperature is low, watering should be controlled to prevent the pot soil from being too wet. Too wet pot soil will cause plant root rot and death, but the pot soil should not be made too dry.
4. Insulation
The suitable temperature for the growth of Clivia in winter is 15-20℃, and it is best not to be lower than 10℃. The temperature should be kept at about 18°C ??after the arrows are released, and the temperature difference between day and night is best at about 10°C. Otherwise, the flowers and arrows will bloom before they grow to an appropriate height, which will easily lead to "pinched arrows". When the outdoor temperature falls below 10°C at night, the Clivia must be moved indoors. When the indoor temperature is lower than 10°C, in addition to covering the surface of the pot soil with a layer of 1 cm thick charcoal powder for insulation, the flower pot must also be placed in a sunny and warm place indoors.
5. Light
Clivia blooms easily under short-day conditions. Exposure to the scorching sun and direct sunlight in summer can cause sunburn and inhibit growth. It should be cultivated under a shade shed or in a semi-shady environment without direct sunlight from May to September every year. But the longer the sun exposure in winter, the better. Low light during flowering can extend the flowering period. It likes warmth and coolness, and avoids severe cold and heat. It generally grows well at a temperature of 18-20°C and stops growing below 5°C. After the Clivia enters the room, the light is restricted and the flower pot needs to be manually moved for adjustment.
