Growth Habits of Calla

Calla originated in southern Africa, like warm, humid and sunny environment, not cold and drought. The optimum temperature for growth is 15~25℃, and the temperature at night is not lower than 13℃. If the temperature is higher than 25℃ or lower than 5℃, it is forced to dormancy. Like water, the soil should be kept moist during the growth period, and watering should be controlled after the tuber enters the dormant state during the summer high temperature period. Soil requirements fertile, good water retention performance of clay loam, pH value between 6.0~6.5.

Breeding method of calla lily

1. Plant division: When the old leaves gradually wither after flowering in May to June, and new leaves grow out or when the pots are changed in mid-September, the small tubers around the mother plants are peeled off and the pots are graded. It usually blooms three months after planting.

2, sowing: mainly indoor pot sowing, germination temperature is 18~24℃, germination after 15~20 days, seedlings need to cultivate 3~4 years to bloom.

How do potted calla lilies grow?

1. Soil: The cultivation basin soil of Calla is suitable for selecting sandy acidic soil with good ventilation and drainage. The bottom of the basin soil is best padded with a layer of coarse sand to facilitate the growth of calla lily, and then matched with one-third of the garden soil and rotten leaves. Add a small amount of organic fertilizer. It is best to choose shallow pots for planting calla lilies.

2, temperature: Calla lily likes a semi-cloudy environment, avoid placing under strong light. The optimum temperature for calla's growth is 22-30 ℃. Below 20 degrees, horseshoes grow slowly. It may even stop growing. Calla lilies like warm, humid environments, so winter, pay special attention to keep them warm.

3. Watering: Calla watering needs to be watered according to the dryness of the pot soil. Look at the soil before watering. At ordinary times, water can be sprayed on the surface of the basin soil and flower surface to keep the basin soil moist. Calla lily growth period like sufficient water, to often leaf, ground watering, and pay attention to leaf cleaning.

4, light: calla lily in the initial growth stage is more tolerant of shade, in its vigorous growth must have a very sufficient light, flowering period more need to have sufficient light, in order to ensure that it flowers and leaves luxuriant. If the calla flower period of insufficient light, it is easy to cause green buds or do not bloom.

5. Fertilization: Fertilize every 20 days during the growth period of calla lily, select decomposed bean cake water, apply thin fertilizer frequently in the growth season, once every 10 days. When fertilizing, do not pour fertilizer water from the leaf sheath to avoid causing calla lily decay and death. Less fertilizer may cause yellow leaves, malnutrition, and too much fertilizer, but also easy to cause yellow leaves of calla lily.

6. Diseases and pests: Calla tubers are prone to rot during dormancy or storage. Antibacterial agent 401 acetic acid solution 1000 times can be sprayed on the tuber surface, dried and stored. Red spider and thrips were used to kill the pests. 50% ethyl acaricide 1000 times solution and 2.5% cypermethrin EC 4000 times solution were sprayed respectively.

What about yellow leaves?

1, too much watering: calla love wet, from the bud can not lack water, should be watered every day, but too much watering, will lead to yellow leaves. Water calla lily to see dry that is, irrigation, irrigation thoroughly, avoid too much.

2. Too little watering: Calla lilies are wet flowers, and drought and lack of water are also easy to cause yellow leaves. Pay attention to keeping watering and keeping enough water, but also pay attention to avoiding wet leaves, so as not to cause soft rot.

3, humidity is too low: calla growth has certain requirements for air humidity, air humidity control between 70~85% is appropriate, less than 50% when the leaves will also have yellow phenomenon. To often water, spray water, keep the basin soil and environment moist, moderate ventilation to keep the air fresh circulation.

4. Excessive fertilization: Excessive fertilization of calla lily will cause thick fertilizer to burn roots, which is the most common cause of yellowing of calla lily leaves. Calla fertilization should be appropriate according to the growth period.

5, too little fertilizer: calla is good fertilizer, too little fertilizer will cause yellow leaves. Generally, decomposed liquid fertilizer is applied once every 10~15 days, and phosphorus fertilizer is mainly applied during flowering.

6, the temperature is too low: Calla cultivation should pay attention to the temperature, temperature control between 20~25℃ is appropriate, afraid of cold, avoid salt alkali, winter night can not be lower than 10℃, too high or too low plants easy to appear yellow leaf phenomenon. When the temperature is too low, pay attention to moving into the indoor insulation.

7. Suffering from smoke: Calla lilies are susceptible to smoke damage, and often smoke will cause yellowing of leaves and affect flowering. Calla cultivation should pay attention to air environment problems, pay attention to circulation of air, prevent smoke.
