Its flowering period is from July to September, of which July is the full bloom period.
To make the plant bloom, it needs five hours of light every day, normal light in the morning and evening, and proper shade when the sun is big. In addition, it also needs acid soil as culture medium.
1. Too deep planting: if it is planted deep, the soil will bury the bulb and it will not bloom. So in the process of planting, can not be buried too deep, to leave the top of the bulb.
2. The flowerpot is too small: its growth speed is relatively fast. If the flowerpot space is insufficient, the corm will grow abnormally, so it will not bloom. The depth of the basin can not be too deep, in general, you can bury the root of the plant.
3. Soil quality: it needs acid soil with sufficient nutrients and good drainage capacity. If the soil quality does not conform to its habits, it will not bloom. The solution is to loosen the soil frequently, and change the soil quality during the growth of the plant. If it is found that the soil tends to alkalize, measures should be taken. You can water the soil with ferrous sulfate solution once a month, or use vinegar instead of chemicals.
