Many florists will place some calla lilies at home. On the one hand, they purify the air and are beneficial to physical and mental health. But many people don’t know how to grow calla lilies in water. Generally, the main issues are the selection of pots and plants in the early stage, followed by the supply of nutrient solution and appropriate light temperature during the growth period. At the same time, the propagation methods of calla lilies include sowing and planting. Division method, and also pay attention to the prevention of diseases and insect pests during the growth period of calla lilies. 1. How to grow calla lilies in water

1. Preparation of flower pots

If you want to grow calla lilies in water, flower pots are a prerequisite. It is best to use a ceramic bottle or a sand bottle, then sterilize it, and then add an appropriate amount of water into it. Since hydroculture is an anaerobic culture, it is necessary to ensure zero pollution of water. Clean water is beneficial to plant growth and is the key to hydroponics.

2. Plant selection

If you want to know how to grow calla lilies in water, the most important thing is plant selection. It is best to choose a plant that should not be too large. Generally, calla lily branches are used, and then the rotten roots and excess roots are removed. Then rinse it with water and put it in the flower pot, keeping the water level in the shallow dish balanced. Moreover, in the early stages of growing calla lilies in water, it is best to change the water once a day. After new roots grow, the frequency of water changes can be extended, about once every 2 to 3 days.

3. Preparation of nutrient solution

In the process of water cultivation of calla lilies, nutrient solution is an indispensable and important part, and it is also the root of calla lilies. optimal conditions for growth and development. You can choose to mix 210 grams of potassium dihydrogen phosphate, 220 grams of magnesium sulfate, 450 grams of potassium nitrate, 50 grams of ammonium nitrate, 15 grams of iron ethylenediaminetetraacetate, 2 grams of manganese sulfate, 1.2 grams of zinc sulfate, and 2.3 grams of boric acid. Normal fluid supply is enough 2 to 3 times a day.

4. Light and temperature

Since calla lilies generally have a suitable growth temperature of 15°C to 25°C, they should be placed in a ventilated place indoors in summer. , it needs to be moved indoors in winter. If the temperature is too low, it will directly cause the calla lily to go dormant. And ensure about 5 hours of sunshine every day, which will help the growth and development of the roots. 2. The propagation method of calla lily

1. Division

The propagation of calla lily is mainly based on the division method. Wait until the calla lily enters the dormant period. Finally, remove the small bulbs between the stem buds. When the old leaves slowly turn yellow and wither from May to June, you can pick off the main plant, then peel off the small tubers above and pot them separately. And ensure that the room temperature is between 15°C and 25°C, and it can be placed in a ventilated place. Generally, it will bloom after three months of cultivation.

2. Sowing

Calla lilies should be sown indoors, preferably in a greenhouse with a room temperature of 15°C to 25°C. Or in the sand bed of the greenhouse, use organic matrix soil and ensure good ventilation and drainage, then sow the stripped stems and buds in separate pots, and pour in an appropriate amount of water. It will be ready in about two weeks after sowing. germination. 3. Diseases and pests of calla lilies and treatment methods

1. Soft rot

Soft rot generally appears in the parts of calla lilies close to the ground, and then gradually The lesions will appear upward, and the leaves will curl and fall, and the flower stalks will fall off, which may even directly lead to the withering and death of the plant. It is best to remove diseased plants as soon as possible and use formaldehyde to disinfect the soil. And remove the diseased parts to avoid secondary pollution.

2. Leaf spot disease

Leaf spot disease is a very common pest and disease hazard during the growth period of calla lilies. It mainly manifests on the surface of the leaves. Attached to the leaves, mainly sucking nutrients from the leaves, they appear as round gray dots that gradually expand, causing root rot and withering. The best way is to cut off the diseased leaves, do not water, and spray with an emulsified oil solution every two weeks.

Conclusion: Through the above introduction, we can better understand the care of calla lilies. As long as we master the above points, we can cultivate perfect calla lilies.
