Detailed Explanation of Clivia Seed Sowing and Seedling Methods and Techniques

Seed Harvesting After the Clivia blooms, from the artificial pollination of the last flower, it generally takes 9 months through a series of physiological growth and change processes for the seeds to mature. When the fruit turns from green to ochre-red or bright red, and when lightly pinched by hand it feels firm and makes a ringing sound, it is a sign that the fruit is fully mature. At this time, the fruit and the stalk should be removed from the base, and the seeds should be extracted. For seeds that are plump, normally developed, and have a bud eye (that is, a small black dot), put them into a gauze bag to prepare for sowing and propagation; for those without a bud eye or that are shriveled, because they have no germination ability, they should be discarded.

Sowing Techniques Because the seeds contain a relatively large amount of water, they must be sown quickly after harvesting; otherwise the emergence rate will be low, or they may even lose vitality. Use a clay pot or wooden box with good drainage and air permeability as the container, disinfect it with potassium permanganate solution, and set it aside for use. There are many ways to sow Clivia, but among the methods that use easily found materials, are not technically difficult, and give a high emergence rate, none surpass river sand sowing and sawdust sowing. River sand sowing: take relatively fine river sand, rinse it with clean water and scald it with boiling water for disinfection, then place it in the container and level it off, arrange the seeds on the sand surface at a spacing of about 2 cm, with the bud eye facing downward, and cover with a thin layer of sand. Sawdust sowing: take sawdust from mixed wood of moderate coarseness, disinfect it by stir-frying in a pan or steaming, then put it into the container to a thickness of 7 cm to 10 cm. With the bud eye facing downward and the same spacing as before, cover with sawdust to cover the seeds, water thoroughly, and then cover the container mouth with plastic film or glass.

Moisture Retention and Heat Preservation After Clivia seeds are sown, whether the seedlings emerge quickly, whether the seedlings are uniform, and whether the growth is good all depend on having conditions and an environment with suitable humidity and temperature. River sand has strong permeability but poor water retention; if the pot surface is found to be insufficiently moist, water or spray immediately so that the water content remains at about 40%. Sawdust has both strong permeability and water absorption, so it should be watered or sprayed once a day to keep the sawdust in a moist state. The suitable temperature for Clivia seed germination is between 20°C and 25°C. However, river sand has a lower temperature and sawdust has a higher temperature, so the temperature can be adjusted according to the sowing medium and the season. If temperature and humidity are well controlled, river sand sowing can produce cotyledons in 30 days to 40 days, while sawdust sowing emerges a little earlier.

Transplanting and Final Planting When the seedlings produce one leaf, the nutrients and water stored in the sown seeds have been exhausted, and they begin to enter the nutritional growth period relying on photosynthesis and root absorption. At this time, the seedlings can be moved out of the sowing container for transplanting. Generally, use flower pots with a 10 cm diameter, with loose, well-drained fine culture soil, and plant 3 plants per pot. Before planting, first make 3 holes slightly larger and deeper than the seedlings; after lifting out the seedlings, hold the plant with one hand and insert the root system into the hole, then use the other hand to fill it firmly with fine soil, and finally water thoroughly and place in a shaded area for care for a few days. After that, gradually increase the sunlight exposure time, and apply liquid fertilizer at a concentration of 1 to 20 once every half month or so. As the plants continue to grow, the fertilizer concentration should be increased accordingly. When the young seedlings grow to 3 to 4 leaves, carry out final planting. Still use pots with a 10 cm diameter, plant only one plant per pot, and manage them according to the water and fertilizer management methods for young seedlings.
