Colorful Calla Lily Cultivation Methods and Precautions
This article摘要: An introduction to calla lilies, providing knowledge about flowers, with a detailed introduction below.
Colorful calla lilies are beautiful and easy to care for, but some flower enthusiasts say that they are difficult to rebloom. In fact, colorful calla lilies are relatively easy to cultivate. If they cannot rebloom the second year, it is mostly due to some issues in your care methods. Today, let's talk about how to cultivate colorful calla lilies.
An Introduction to Calla Lilies
Calla lilies are named for their flower shape resembling a horse's hoof and are perennial, robust herbaceous plants with underground tubers that easily grow into clusters. Calla lily leaves are thick and green, making them a plant that is admired for both its flowers and leaves. Colorful calla lilies are even more高端 as potted ornamental flowers, with sturdy stems and rich colors, also serving as high-end cut flower materials.
Calla lilies are toxic and should be avoided for consumption. However, they also have medicinal value, being able to clear heat and detoxify, and when applied externally, they can treat burns and prevent tetanus.
Colorful Calla Lily Cultivation Methods and Precautions
Colorful calla lilies can be planted in the ground or in pots, usually grown as potted ornamental plants because they prefer warm, humid conditions, grow quickly, and bloom profusely. To grow calla lilies well and ensure they bloom every year, it is recommended to focus on the following four points in their care.
1. -- Potting Soil Preparation --
Calla lilies prefer loose, breathable, fertile, neutral, or slightly acidic soil. For potted calla lilies, you can use a general nutrient-rich soil mixed with an appropriate amount of fermented organic fertilizer and some superphosphate. You can also mix sandy soil and decomposed leaf soil in a 2:1 ratio, then add fermented organic fertilizer and superphosphate as a base fertilizer.
If planting calla lily tubers, place them with the top side up, cover with about 5cm of soil, and water thoroughly. If it's a potted calla lily, it should be transplanted with the complete original soil ball, watered thoroughly after transplanting, and placed in a bright area with scattered light to recover.
2. -- Fertilization and Water Management --
Colorful calla lilies prefer a humid environment and are not drought-tolerant. Watering should be done when the surface of the potting soil is dry, or the soil can be kept slightly moist, but not waterlogged. Waterlogging can cause root rot in calla lilies, so each watering should be thorough.
The optimal growing temperature for colorful calla lilies is between 22-30 degrees Celsius, with the normal blooming period in May. During the vigorous growth period in spring, it is recommended to keep the plant well-fertilized and watered, applying a high-phosphorus and potassium fertilizer every 5 days to promote continuous blooming.
In summer, the blooming of colorful calla lilies decreases, and fertilization should continue to nurture the rhizomes. If the temperature is too high, the above-ground parts of the plant may wither and enter a dormant period, at which point watering can be stopped.
3. -- Light Management --
Colorful calla lilies enjoy plenty of light but do not tolerate strong sunlight, especially during the blooming period. Sufficient light is needed to make the flowers bright; otherwise, the flowers may appear green. Therefore, plenty of light should be provided in spring, autumn, and winter, while shading or placing the plant in a bright area with scattered light is necessary in summer.
4. -- Summer and Winter Care --
After the blooming period, colorful calla lilies should continue to be fertilized until mid-summer when the above-ground parts will gradually turn yellow and eventually wither, entering a dormant period. In regions with low winter temperatures, watering can be stopped, and the rhizomes can be dug up and replanted in the autumn with fresh soil.
In warm southern regions, it is recommended to dig up the rhizomes, wrap them in newspaper, and store them in the refrigerator. They can be replanted in autumn, blooming in November and continuing until the following May.
The reason some flower enthusiasts say that calla lilies are not easy to rebloom is usually due to a lack of low-temperature vernalization. Calla lily rhizomes need to be in a 5-degree environment for a month to bloom profusely. Insufficient fertilization is also an important reason. Calla lilies thrive on fertilizer, so more fertilization is needed for more blooms.
