Cultivation methods and precautions for Calla lilies
This article introduces the knowledge about Calla lilies, a bulbous flower, including their cultivation methods and precautions. Here is a comprehensive introduction.
Writing a detailed and practical article on the cultivation methods and precautions for Calla lilies is quite challenging. Flower enthusiasts hope to find fine and useful knowledge about growing Calla lilies in such an article. In order not to disappoint them, we have tried to organize the article logically and make it practical.
Several basic points should be noted to grow Calla lilies well, including environment, soil, fertilizer, and watering.
We must first determine the care environment. Calla lilies are perennial, robust herbs belonging to the Araceae family, similar to Spathiphyllum. They prefer warm, humid, and sunny environments and are intolerant to cold and drought.
The normal growth temperature for Calla lilies is between 15°C and 25°C. Temperatures too high or too low will cause them to enter dormancy. Therefore, we should pay attention to temperature control in the daily care process, although it is not that strict, but avoid frost damage.
Let's talk about the soil next. It is best to grow Calla lilies in sandy soil, keeping the potting soil moist without积水. Other substrates can also be used as long as they have good breathability and water permeability. Just pay attention to controlling the water content.
Calla lilies like moisture. After the leaves grow, they should be watered frequently from the Mid-Autumn Festival to the following spring, keeping the potting soil slightly moist without waterlogging. It's also good to spray water on the leaves and sprinkle water around the ground to increase humidity, which is beneficial for their growth. However, whether spraying or sprinkling water, avoid getting water on the flowers and prevent water from flowing into the leaf heart, as this can easily lead to leaf soft rot. In winter, use water similar in temperature to the room temperature for watering. From late May, reduce the amount of watering to encourage dormancy. Stop watering when the leaves turn yellow and place the Calla lilies in a shady and well-ventilated area where they won't get wet from rain.
Calla lilies enjoy sunlight, prefer long light, and dislike strong light. From the time they start growing leaves in the Mid-Autumn Festival until they bloom in winter and spring, they need plenty of sunlight. Especially after moving them into a greenhouse in winter, they should be provided with full sunlight and maintained at above 10°C. They start to form buds from the New Year to before the Spring Festival and reach full bloom in March and April. Insufficient sunlight in winter can delay blooming, or they may only form buds without flowering, or the buds may gradually turn green and wither. Move them to a well-ventilated and shady place in late May. During the hot summer, which is their dormant period, reduce watering and fertilizing, and provide appropriate shading when sunlight is strong.
For Calla lily propagation, we can choose to propagate by division or bulb division. For division propagation, after the main flowering period or after dormancy, dig up the robust mother plant tubers, divide a clump into 2-3 clumps based on the size of the original tubers and the number of buds, and plant them separately with 2-3 buds per clump. With normal management, they can bloom in 3 months. For bulb division, after normal division during the dormant period, some smaller tubers are cut off. These small tubers need to be cultivated in the open for 1-2 years before they can become flowering bulbs.
The above content on the cultivation methods and precautions for Calla lilies is for reference by green plant enthusiasts and is hoped to solve your problems in green plant and flower management.
