They are delicate and straight. The leaves are green and the stems are slender. They are light and colorful, green and dripping. The yellowish calla of the Calla Lily grows, and in the upright flower bud, it looks like it sits in a holy rosette, and it is also called "Kuanyin". The calla lily has a unique shape with yellow and white flowers. Therefore, it is a good material for decorating the hall and the study, and it is also one of the most popular potted ornamental flowers. How to make Zantedeschia more flowering? Should do the following: First, potted soil should contain slightly acidic, calla lily loose fertile slightly acidic soil. Pottery soil should choose well-drained, sandy loam rich in humus. 4 soils, 2 composts, 3 humus, and 1 sand can be used. Calla lily growth is dominated by basal fertilization. The lack of fertilizer or excessive fertilization during the growth process can cause yellow leaves, so pay attention to basal fertilization. Between the two flowering periods, after the first flowering, it is better to change the basin and add new soil. After its resumption of growth, the basal fertilizer will play a role. If it is heated again, it can promote its secondary flowering, so Shiji fertilizer is one of the keys to ensure more flowering. Second, growth and flowering should pay attention to full watering, calla lily has "pouring undead Calla Lily" said. Therefore, it is necessary to fully water in the growth and flowering period, and require the soil to be moist. If the soil moisture is insufficient, petiole breakage often occurs. However, the amount of watering should be reduced after flowering to facilitate hibernation. Third, pay attention to the light required for different stages of growth. The requirements for light vary according to the stage of growth. Calla lily begins to grow and is more shade-resistant; it enters a vigorous growth stage and requires sufficient light; it takes more time to reach the flowering stage. There is plenty of light, but it likes long light, not strong light. In particular, it is strictly prohibited in the hot sun during the summer. If the light is insufficient, it will only twitch without flowering, and even the calyx will gradually turn green and dry. Fourth, cutting old leaves to promote flower buds, calla lily is a perennial herb, can bloom many times a year, to make it flowering and frequent, is to make it less long leaves and more flowering, that is often cut off the old leaves To promote new students. Fifth, warm winter shade in winter, calla lily, hi warm, winter indoors should be maintained at 15 °C during the day, not less than 10 °C at night is appropriate. Keep the basin wet, every 7-10 days, top-dressing thin fertilizer once, before and after the Spring Festival to flower. After the flowering, the fireproofing furnace smoke pollution, otherwise it will cause falling flowers, yellow leaves, poor growth; after June, the calla lily leaves gradually yellow, enter the dormancy period, then you must cut off the dead leaves, control watering, stop fertilizing, flower Move the basin to a cool, ventilated place and allow it to sleep. At this time, it is not appropriate to put the pot in the dry place.
