How to cultivate Zantedeschia
The following is an introduction to the cultivation of Zantedeschia and the hydroponic method of planting green plants and flowers:
Zantedeschia is a herbaceous plant of the Zantedeschia genus, which is very common in life. Many people enjoy cultivating Zantedeschia at home. While most plants are cultivated in soil, Zantedeschia can be grown both in soil and hydroponically. Many people prefer hydroponically grown Zantedeschia, as it looks cleaner and brighter. So, do you know how to hydroponically grow Zantedeschia?
1. Selection of Hydroponic Plants
Hydroponic Zantedeschia plants should not be too large; it's best to choose Zantedeschia tillers and wash the plant roots clean, removing decayed roots and overly long roots. During the initial phase of hydroponics, change the water once a day to prevent water pollution and promote the growth of new roots. Once new roots have grown, you can extend the interval between water changes appropriately. If possible, add a few drops of nutrient solution every 20 days to make the plant grow stronger.
2. Preparation of Hydroponic Nutrient Solution
The hydroponic nutrient solution for Zantedeschia can use the following formula: Calcium nitrate 800g, Monopotassium phosphate 210g, Magnesium sulfate 250g, Potassium nitrate 500g, Ammonium nitrate 30g, EDTA iron salt 10g, Manganese sulfate 2g, Zinc sulfate 1g, Boric acid 1.3g, Copper sulfate 0.15g, and Ammonium molybdate 0.1g. In the early growth stage, the nutrient solution concentration can be controlled at 1.2ms/cm; in the mid-late growth stage, it can be appropriately increased to 1.5ms/cm. Throughout the growth period, control the nutrient solution pH between 5.6 and 6.5. The supply of nutrient solution mainly depends on the weather conditions and the size of the plant. Generally, supply the solution 2-3 times a day to keep the cultivation medium moist, with a shallow water layer at the bottom of the tank.
3. Hydroponic Management and Disease and Pest Control
The management of Zantedeschia plants is relatively simple, mainly involving removing yellow leaves and some outer leaves. The purpose of removing outer leaves is to prevent leaf congestion from affecting light and ventilation and to allow flower stems to extend. According to miaomu.w.cn, the main diseases and pests of Zantedeschia include bacterial soft rot, aphids, and red spiders. Bacterial soft rot can affect leaves, petioles, and tubers, mainly transmitted by tubers. When the disease first appears, it can be controlled by spraying a Bordeaux mixture at 500 times.
Points to Consider When Hydroponically Growing Zantedeschia
Zantedeschia requires fresh air to grow and bloom. It is very sensitive to kitchen fumes and toxic gases, so hydroponic Zantedeschia should be placed away from the kitchen to avoid dust pollution. During the growing season, Zantedeschia needs plenty of sunlight, so it should be allowed to bask in the sun as much as possible in winter.
Also, when growing Zantedeschia hydroponically, ensure good air circulation. If ventilation is poor and the temperature is higher than natural air temperature, it can lead to pests such as mealybugs, aphids, and leaf rollers. If found, spray with a 1500-2000 times dilution of dimethoate to kill the pests.
Hydroponic Zantedeschia cultivation is essentially an oxygen-deficient method, so zero pollution must be maintained. If the nutrient solution is contaminated by microorganisms, it will consume the dissolved oxygen in the water. Therefore, maintaining the cleanliness and inorganic nature of the nutrient solution and keeping the necessary level of dissolved oxygen in the solution is key to hydroponic Zantedeschia cultivation.
