How to plant calla lily

1. Calla lily breeding soil selection

Calla lily is suitable for 30 to 40 cm in diameter and deeper clay pots, purple sand pots planting, it is good to be born in a deep fertile, loose slightly acidic sandy loam, can be used in rotting soil, garden soil, fine sand mixed into a cultured soil at the ratio of 6:3:1.

2. Fertilization method of calla lily

Calla lily likes fertilizer, from the long leaves to the calla lily before flowering to thin fertilizer, every 10 days or so, 1 time to apply nitrogen, phosphorus, potassium composite liquid or granular fertilizer. Fertilizer should pay attention to do not drop liquid fertilizer on the leaf surface, so as not to cause rot; do not apply nitrogen fertilizer alone, anti-leaf more flowers less or no flowers. Ferrous sulfate can make the leaves bigger, thicker, greener, smooth and shiny, petiole is not easy to grow, so as to ensure that the leaves are beautiful, and at the same time can promote the formation of flower buds, prolong the flowering period. The specific method is: dilute ferrous sulfate into a 7% solution, every 1 month watering 1 time, each time to water through.

3. Watering method of calla lily

Calla lily likes moist, long leaves from mid-autumn to the following spring should be often watering, often keep the potting soil wet and not water as well, and often spray water to the foliage and sprinkle the ground near the water to increase air humidity, and its growth. But whether spraying or sprinkling should avoid spraying water on the flowers, and prevent the water flow to the heart of the leaves, otherwise it is easy to lead to leaf soft rot. In winter to use water with room temperature similar to watering spray. late May should be to reduce the amount of watering, to promote its dormancy, after the yellow leaves to stop watering, will be placed in the horseshoe lily can not rain in a cool ventilated place.

4. Calla lily breeding temperature requirements

Calla lily growth temperature 15 ~ 25 ℃, below 10 ℃ is delayed flowering, below 5 ℃ growth stagnation, 0 ℃ may cause death. In the spring, it is desirable to stabilize the minimum temperature at 10 ℃ out of the shed.

5. Calla lily breeding light requirements

Calla lily good sunshine, like long light, avoid strong light. From the mid-autumn long leaves until the winter and spring flowering should see more sunlight, especially after moving into the shed in winter, to give full light, to maintain more than 10 ℃, New Year's Day to the Spring Festival before the beginning of bracts, March to April up to the blooming period. Insufficient light in winter, the flowering period is delayed, or only bracts do not bloom, and even bracts gradually become green and shriveled. late May to ventilate the shade. Summer heat period is its dormant period, reduce watering and fertilization, the sun is strong need to appropriate shade.

6. Calla Lily culture of potting method

potting or potting soil should be in the autumn after the mid-August to mid-September, too early, the dormant period is short, tiller tuber has not yet full, affecting the growth; too late, the flowering period is delayed and shortened. It is appropriate to pot a layer of broken hard plastic foam pad at the bottom of the pot to enhance ventilation and drainage, to prevent root rot, and add some bone meal and nitrogen, phosphorus, potassium composite fertilizer in the culture soil. When planting, select the sturdy tuber with buds, planting 4 to 5 buds per pot, trimming the senescent part of the bottom of the ball and the small buds sprouting around it. Plant 3 to 5 plants per pot, the buds should be placed squarely on the top, mulch a little thicker. Then water, placed in the shade, and then move to a sunny place after the leaf buds grow.

Precautions for Calla Lily cultivation

(1) When applying fertilizer, be careful not to splash the fertilizer on the leaf surface, in order to prevent the leaves from scorching, yellowing, and early wilting of the lower foot leaves.

(2) change the pot once a year, change the pot, pot vine put some dry fertilizer as base fertilizer, potting soil is best to use loose, fertile sandy soil. Avoid smoke, such as smoke leaves turn yellow, affecting growth and flowering. Sex like moisture, can not be subjected to direct sunlight, such as sun exposure to cause leaf yellowing and withering.

(3) when the leaves become thin, is the phenomenon of lack of fertilizer, to strengthen the fertilization. In the vigorous growth of the base of the old leaves should be removed in a timely manner to promote the growth of new leaves and buds, after flowering to cut off the withered flower stalks, placed in a cool place dormant, and control watering.

(4) generally planted 3 to 4 years later, the plant has not been able to robust growth, this time to use the cut stem method for renewal: in the fall in the potting, the tuber cut off from the middle, in the incision coated with soil slurry, placed in a cool place for 1 to 2 days and then planted into pots, spraying the foliage with water to keep the potting soil a little dry, 1 month after the roots can be born.

Basic knowledge of horseshoe lily breeding

Best breeding time: horseshoe lily in June to July into the dormant period, this time you can take off the bulb around the mature plant to breed new potted plants. The most suitable season for breeding is August to September. Separation and propagation must be in the fall, otherwise it is difficult to bloom that year, or bloom, the flowering period is also late.

Best growing soil: calla lily breeding soil to sandy loam soil with garden soil and rotting leaves each 1/3, then mixed with 1/5 organic fertilizer. Because its root system grows in the upper part of the sphere, so the bottom layer of potting soil should be padded with water permeable slag or coarse grain sand. Then with one-third of the garden soil and rotting leaves. And add a small amount of organic fertilizer.

Growth and humidity requirements: calla lilies like moist, fertile soil.

Optimal growing temperature: The optimal temperature for the growth of calla lily is 22-30 ℃. Temperature below 20 ℃ or less, horseshoe growth will become slow. It will even stop growing. Calla lilies like a warm, moist environment, so over the winter, pay special attention to the calla lilies to keep warm. Avoid high temperatures in the greenhouse, especially when the relative humidity is high.
