What should be noted when growing potted colored calla lilies? We have asked experienced netizens to help introduce this.Zhongdi Web has compiled the key points to note for potted colored calla lilies, listed below for netizens' reference.
Point one,The potting soil for potted colored calla lilies should be mainly sandy loam, and can be mixed with 1/3 garden soil and 1/3 leaf mold, then mixed with 1/5 organic fertilizer to grow colored calla lilies. Because their roots grow on the upper part of the bulb, the bottom layer of the potting soil should be lined with permeable and breathable furnace slag or coarse sand. The flowerpot should be a shallow pot, not a cylindrical pot.
Point two,Fertilizing colored calla lilies should be mainly with phosphorus and potassium fertilizers, especially when the scape emerges and buds appear, spray a potassium dihydrogen phosphate solution in time at a concentration of 0.1% to 0.2%, to promote thick, straight and lodging-resistant peduncles. If saving seeds, after fruit set, spray once every 10 days, 2 to 3 times in total. Potted plants have limited nutrients, so apply thin fertilizer frequently to continuously replenish the nutrients in the potting soil.
Point three,Colored calla lilies, like ordinary white calla lilies, like a warm and humid environment and are not drought-tolerant. The potting soil should be kept moist and must not lack water. If the environment is dry, spray water on the ground to maintain a humid micro-environment.
Colored calla lilies like sunlight, but are afraid of exposure to the sun in summer. After direct sunlight, the leaves and spathes will be scorched. Therefore, shade is needed in summer, with a shading rate of 50%. But if they grow for a long time in a dark environment with insufficient sunlight, flowering will be affected, or they may not flower at all; even if they flower, the color will be pale and poor for viewing. In spring and autumn, shading is not necessary.
Point four,Colored calla lilies are not cold-tolerant and like warmth. When planted in the Liaonan area, division and potting are generally done in September in autumn. Each pot can hold three flowering bulbs of the same diameter, planted in a triangular arrangement. They can take root in autumn, go dormant in winter, and be stored indoors, keeping at 5°C, with the flowerpots stacked. By the next spring, when the temperature is 10°C to 15°C, watering is needed. If the indoor temperature is high and sprouting is early, they generally bloom in June and July; in some cases with high temperature and good management, flowers can be seen in early June.
