How should Clivia be cared for so it produces more seeds?

In spring, Clivia blooms one after another with beautiful flowers. However, although some flower growers put in effort with management, because the method is wrong, after the Clivia flowers fade, not a single seed grows. In order to rapidly propagate the Clivia they grow, these flower growers are eager to know how to manage things so that Clivia sets seed. You might as well tell them to do this:

When Clivia is about to bloom, it should be placed in a spot with a temperature of 15°C to 25°C and about 4 hours of direct sunlight per day. Stop topdressing, and do not water too much or too little; just keep the soil slightly moist. Some flower growers, in order to enjoy the flowers for a few more days, put the Clivia in a low-temperature, low-light place; or, fearing there is not enough fertilizer, they heavily topdress, and when there is not enough water they keep watering. This kind of management is unfavorable for Clivia setting seed and should be avoided.

After Clivia blooms, timely pollination is very important. The best time to pollinate Clivia is 2 days after its petals open, when the stigma of the pistil secretes a shiny liquid and the anthers of the stamens release pollen. The specific pollination time is 9 a.m. to 11 a.m. each day, when the pollination effect is best. When pollinating, dip the anther onto the surface of a cotton swab wrapped around a small stick and tap or smear it onto the stigma. The next day, pollinate once more in the above way. After the fertilized Clivia flowers fade, good conditions favorable to plant growth must be created. Especially after summer begins, not only must the Clivia plant bearing immature seeds be shaded, cooled, and protected from the summer heat, but watering must also be controlled and fertilizing stopped. Prevent the plant from growing weak or the root system from rotting due to improper management, as this easily causes the seeds to drop.

Clivia seeds mature from July to September after pollination, and this can be judged by the color of the fruit skin. When the color of the Clivia fruit skin slowly turns from green to red, it indicates that the seeds inside are already mature. At this point they can be removed in batches for sowing.
