Detailed Guide to Clivia Cultivation and Care Methods
Clivia is beautiful in leaf, flower and fruit alike; in particular, its large leaves stay verdant and glossy green through all four seasons, with elegant leaf form, noble and dignified. When in bloom, green leaves and red flowers set each other off, the flower colors splendid yet not gaudy, with a graceful and poised bearing, all the more eye-catching and moving. It is a potted flower prized for both foliage and blossoms. Especially since its full bloom coincides with the Spring Festival, it is deeply welcomed by urban and rural residents and has become an excellent choice for decorating halls, conference venues or adorning rooms.
2. Ecological Habits
The base of Clivia miniata forms a pseudobulb from the leaf bases. The leaves are arranged in two ranks, broadly strap-shaped, with rounded blunt tips and entire margins, hard, thick and glossy in texture. The flower stalk is upright, flat, about 30-40 cm tall. The umbel is terminal, with several imbricate bracts. The small flowers number from a few to several dozen, funnel-shaped. The perianth has 6 lobes, fused, orange-red outside and tinged with yellow inside. The berry is spherical; the flowering period is between spring and summer. Clivia nobilis has slightly drooping flowers with a narrowly funnel-shaped perianth, smaller than the former species. There are many horticultural varieties of clivia; superior clivia leaves reach more than 9-10 cm in width, with glossy leaf color, upright leaf posture, rounded blunt leaf tips, distinctly raised veins, thick and fleshy leaves, sturdy and full flower stalks, large flowers, and numerous and vivid blooms. Examples include Da Shengli, Ranchang, Youjiang Da Laochen, Er Shengli, Huang Jishi Duan Ye Heshang, Yuantou, Baotou Heshang, Chuncheng Duan Ye, and others.
Native to southern Africa. It prefers semi-shade. It fears direct strong light. It likes a warm, cool climate. It requires fertile, loose, well-aerated, slightly acidic soil.
3. Key Cultivation Points
(1) Potting Soil
For potting, use a mix of sand and peat, or sand and leaf mold. For mature seedlings, repot once every 2-3 years, with pot size determined by the seedling. When repotting, change the soil, and compost it together with cake fertilizer, barnyard manure, etc., to promote rapid growth of clivia.
(2) Watering
Clivia likes a warm, humid environment. Its fleshy roots are well developed and it has a certain drought tolerance, but it fears waterlogging. When watering, follow the principle of alternating dry and wet; ordinarily it is best to keep the relative soil humidity at 80%-90%, and no lower than 60%. Wiping the leaf surface with tea water every week can keep the leaves fresh and glossy. In short, for clivia in all four seasons, as long as you avoid wind in spring, protect from sun in summer, prevent rain exposure in autumn, and keep it from drying out in winter, the plant can be kept growing vigorously with abundant flowers and lush leaves.
(3) Fertilizing
Clivia can be fertilized 1 month after potting and seedling establishment; apply fertilizer water once every 10-15 days, and stop applying in summer. Half a month before the two growth peaks in spring, it is advisable to apply dry soybean cake or chicken manure on the pot surface, but not too close to the roots, so as not to damage them. After autumn, it begins to form buds and bloom, and at this time phosphorus fertilizer should be increased to make the flowers large and brightly colored and to prevent "arrow clamping" (bud sticking). When fertilizing, do not splash it onto the leaves or into the leaf sheaths. If fertilizer is insufficient, the leaves lose their luster, the flowers are few and small, and the phenomenon of blooming every other year may also occur. Carry out regular topdressing, generally in spring and autumn, with less in summer and winter.
(4) Light
Clivia has broad, large leaves and a certain shade tolerance; it likes a semi-shade environment. Plants grown under 50% light transmittance have verdant, emerald-green leaves, which can greatly enhance the ornamental effect. Light also affects the arrangement direction of clivia leaves; if light comes from only one side, the leaves originally arranged in a single row will become disordered, leading to a decline in ornamental effect, so be sure to let the plant receive light evenly and regularly rotate the pot's direction.
(5) Temperature
The suitable temperature for clivia is 15-20°C. When above 25°C, the plant grows poorly, often with leggy leaves, affecting flower bud differentiation; at this time, pay attention to ventilation and cooling. Below 10°C, growth is slow; when it drops below 0°C, the plant will freeze to death. In summer, pay attention to cooling, which can promote flower bud differentiation. A large day-night temperature difference is beneficial to clivia growth, generally 6-10°C is suitable.
