Detailed Explanation of the Cultivation Methods and Technical Key Points for the Large-Flowered Clivia (Clivia miniata)
The main propagation method is by sowing seeds, though division can also be used.
When the fruit turns red and the seeds are ripe, peel off the fruit skin, place the seeds with the hilum facing down, and sow them in a shallow wooden box filled with pure sand or sawdust, keeping the temperature at 20-23°C; they will germinate in 30-40 days. When the first leaf grows to 2 cm, transplant into a small pot.
The growing temperature should be controlled between 15-25°C. In winter, keep it above 15°C for normal flowering.
During the seedling stage, water requirements are relatively low; during the flowering period, water requirements increase, watering once every 2-3 days, and the water should be left to stand for several days before use. After 3-4 years of planting, it flowers and fruits every year, requiring soil replacement annually and regular fertilization. Apply less fertilizer to small seedlings and more to plants with 8-9 leaves. In autumn, apply once every 10-20 days; in winter, once every 20-30 days; do not apply in summer. Mainly use cake fertilizer water, cooked perilla seeds, and flax.
The leaves should form a straight line when viewed from the side and look like a fan when viewed from the front; rotate the plant once every 7-10 days. Wipe the leaves clean with a cloth dipped in water.
When the flower scape is emerging, raise the temperature to 20°C and strengthen water and fertilizer management to prevent the scape from getting stuck.
Clivia must be cross-pollinated; pollinate between 9-10 o'clock, and the fruit ripens in 7-9 months. When the fruit is red, pick it together with the stalk, and sow immediately after harvesting.
Boil coarse sand for 20 minutes, let it cool, then place it in a shallow wooden box as a substrate; sow at a spacing of 1-3 cm, cover with sand, and spray thoroughly with water. It can also be sown in clean sawdust. The flowers, fruits, and leaves are all beautiful, and it blooms in winter and spring, making it an important greenhouse ornamental.
