Calla lily is a commonly used flower for marriage, which is often missing. The reason is that the cultivation techniques are not in place.

Cultivation techniques

Potted plant

The soil basin soil should be fertile, neutral or slightly acidic. It can be made by mixing 2 parts of fine broken pond soil (or clayey fine sand soil) and 1 part of rotten leaf soil (or compost), adding appropriate amount of calcium superphosphate and mature human and animal manure.

Usually after anthesis, the bulbs around the tubers are peeled and cultured for one year, and then blossom next year. Through the experiment, the author found that the root-tillering method could blossom in the same year.

The specific approach is: from late June to early August, combined with changing the basin, the well-developed large ramet with roots will be broken by hand (preferably without a knife) and planted in the prepared basin. If it is used as a cut flower, 2 or 3 more ramets can be planted and placed in a cool place. Using this method to propagate, it can blossom from September to October of that year.

Administration and Management

Light temperature: calla lilies like warm, humid and slightly shaded environment, but the flowering period should be sunny, otherwise the flame bracts will be green and affect the quality. It is necessary to ensure that the light lasts for 5 hours every day, otherwise the petiole will lengthen and affect the ornamental value. Calla lilies are not cold-resistant and will be moved into the greenhouse in mid-October. In summer, under the condition of shade, we often spray water to cool and moisturize.

Watering and fertilization: calla lilies like moist and fertile soil, which is often called "big fat and big water". They should be watered more during their growth. Topdressing can be applied alternately with liquid fertilizer such as rotten bean cake water and chemical fertilizer (compound fertilizer or diammonium phosphate), once every 2 weeks. When topdressing liquid fertilizer, do not pour fertilizer and water into the leaf sheath to avoid decay. It was mentioned before: "stop fattening when you see the buds." After the experiment and comparison, the author thinks that the amount of fertilizer should be increased after seeing the bud, so as to ensure its long flowering period, large and colorful flowers, and make the buds bloom continuously and blossom all the year round.

The use of ferrous sulfate: in potted calla, the application of ferrous sulfate is an important part of the experiment. The application of ferrous sulfate can make the leaves of calla lilies bigger, thicker, green, smooth and shiny, and the petiole is not easy to elongate, so as to ensure the beauty of the leaves. At the same time, it can promote the formation of buds and prolong the florescence. The specific method is to dilute ferrous sulfate into a 2% solution and pour it once every one month, each time thoroughly.

Reproduction method

The main way of reproduction is to divide balls. After the plant enters the dormant period, peel off the small balls around the tuber and plant it separately. It can also be sown and propagated, and the seeds can be sown in pots as soon as the seeds are ripe. The suitable temperature for germination is about 20 ℃.

Ramet: when the old leaves withered gradually after flowering from May to June, and when new leaves grew or changed pots in the middle of September, the small tubers around the mother plant were peeled off and put on the pot by stages. It usually blossoms 3 months after planting.

Taboo

Avoid low temperature drying. Calla lotus likes to be warm and humid, not cold-resistant, and the indoor temperature should not be lower than 10 ℃ in winter, otherwise it will affect flowering. During the growth and flowering period, pay attention to keep the basin soil moist, and often spray the leaves with warm water to keep fresh green and fresh.

Avoid smoke pollution. Calla lily cattle blossom requires fresh air and is sensitive to smoke. Stove soot and oil fume will make calla lilies grow poorly, resulting in yellow leaves and falling flowers.

There is not enough light. Calla lilies like light during their growth and flowering; especially when they bloom before and after the Spring Festival, if there is not enough light, it will cause the bud not to bloom and fall.

Avoid poor ventilation. Poor indoor ventilation in winter, often caused by shell insects, and accompanied by the occurrence of soot disease. When the number of bright insects is small, it can be brushed off with a soft brush. Soot disease can be scrubbed with clean water; in severe cases, 1500 times topiramate or carbendazim can be sprayed to control the disease.

Pest control

Tubers are prone to rot during dormancy or during storage. 1000-fold solution of acetic acid solution can be used to spray the surface of tubers and store them after drying. The pests were harmed by red spiders and thrips, which were sprayed with 1000 times of 50% ethyl acaryl alcohol and 4000 times of 2.5% deltamethrin EC, respectively.
