The suitable temperature for the growth of celadon is about 15-25 ℃. Avoid high temperature in summer, when the temperature is more than 30 ℃, the plant will enter a semi dormancy state; in winter, it is better to keep the room temperature above 10 ℃, and the temperature shall not be less than 5 ℃, otherwise it is easy to freeze.
Lantern like sunny environment, if the sunshine is insufficient, it is easy to cause the plants to grow in vain, and the number of flowers will be greatly reduced. However, in summer, it is necessary to properly shade the plants, move them to a cool and ventilated place, avoid direct sunlight for a long time, and avoid leaf curling.
During the growing period, the basin soil should be kept moist, and the principle of "see dry and see wet" should be adhered to. Do not let the potting soil be too dry or too wet during the flowering of the lantern flower, otherwise it will easily cause the phenomenon of falling buds, flowers or leaves. In summer and winter, it is necessary to control watering to prevent defoliation and rotten roots.
Lantern blossom likes fertilizer, and sufficient organic fertilizer is applied before planting. Because the growth speed of the lantern flower is relatively fast, and it can bloom continuously, so the long-term growth should be applied once every 7-10 days, such as cake fertilizer or thin liquid fertilizer, etc., the nitrogen fertilizer should be controlled in the early growth stage, and the phosphorus and potassium fertilizer should be applied in the flowering stage.
The cultivation medium is suitable for the selection of fertile, loose and permeable sandy loam with good drainage.
In spring, we can change pots and soil, pour out some pots and soil, cut off the roots properly, and select the right flowerpot. In spring and autumn, the soil should be loosened properly.
