How to Grow Calla Lilies? A Detailed Guide to the Latest Growing Techniques
I wonder if you have ever seen the calla lily? Its leaves are emerald green and its flowers are brightly colored, with the common flower colors being red, white and pink. It is very beautiful and has high ornamental value, and we can try growing a few plants ourselves, so how do you grow calla lilies?
1. Soil: Calla lilies like loose leaf mold soil with good air permeability and drainage, and leaf mold soil can also effectively retain water. At the same time, perlite or peat soil mixed with sand can be used, all of which can effectively maintain the soil's good drainage and air permeability. Because its roots grow on the upper part of the bulb, put some permeable, breathable coal cinders or coarse sand at the bottom of the pot soil.
2. Temperature: Calla lilies like a warm environment and are especially not cold-tolerant. They grow well between 15°C and 25°C. High and low temperatures will stop the calla lily's growth or even kill it. In summer, when it is above 25°C, sprinkle some water on the leaf surface to cool it down, or move it to a shady place. In winter, it is best to keep the indoor temperature above 10°C, as too low a temperature may cause cold damage.
3. Humidity: Calla lilies often grow in swamps, and they very much like a warm and humid environment. If you want to grow calla lilies at home, you need to maintain high humidity in their growing environment.
4. Light: Calla lilies like a semi-shady environment and cannot accept direct strong light, otherwise it will scorch the leaves. But if you want calla lilies to bloom more, it is best to let them receive the warm sunlight of morning and evening. In summer, during the season of high temperatures and strong light, they must be properly shaded. In winter, when the light becomes weaker, you can place the calla lily in a sunny spot indoors to supplement light.
5. Watering: Calla lilies like to grow in a relatively moist environment, so during cultivation you must do a good job of watering and care. When the soil is slightly dry, water it promptly, and also water the soil thoroughly, so as to ensure its moist environment. But do not water too much; once there is too much water and it accumulates, it will affect its growth and may even cause root rot. In winter, because the temperature is low and water evaporates very slowly, you can reduce the frequency of watering.
6. Fertilizing: During the growing period, you can apply decomposed bean cake water to the calla lily once every 20 days; during the period of fastest growth, you can apply a dilute fertilizer solution once every ten days, mainly nitrogen, phosphorus and potassium fertilizers. Before the flowering period, reduce the application of nitrogen fertilizer and increase the application of phosphorus and potassium fertilizers. Do not apply too much fertilizer, and do not let it splash onto the leaves, to avoid burning the roots and scorching or yellowing the leaves.
7. Pest and disease control: The more common pests and diseases of calla lilies include: leaf mold, leaf spot, root rot, and seed flies. Leaf mold makes the leaves turn yellow and develop patches of different sizes; leaf spot produces light brown to yellow-brown lesions; root rot causes the lower leaves of the plant to wither first, then spreads to the inner leaves. Different diseases should be treated with different control methods. You can go to the market to choose control solutions specifically for the disease. In general, you should usually strengthen plant management and keep the room ventilated.
