How to raise water bamboo in winter will not die
In the cold winter, the yellowing and wilting of water bamboo leaves has become a problem that plagues growers. As a leaf-viewing plant that likes temperature and is afraid of cold, winter maintenance of water bamboo requires mastering the three core elements of temperature, light and water quality. This article will systematically analyze the secret of wintering through five dimensions, so that your water bamboo can remain green and dripping in the cold winter. Environmental regulation: Key temperature management for wintering of water bamboo When the temperature fell below 10 ℃, water bamboo began to stagnate growth. It is recommended to move the plants into an indoor sun room and maintain the ideal temperature range of 15 - 25 ℃. Heating areas in the north need to pay attention to staying more than 2 meters away from the radiator to avoid dehydration and scorching of the leaves. Ventilation management Open windows for ventilation for 30 minutes every day from 11:00 to 14:00 at noon, which can effectively prevent pests and diseases such as red spiders. In case of cold weather, a micro greenhouse can be formed by hanging a transparent plastic film above the plants. Light and nutrient supply Light enhancement In winter, direct light should be ensured for ≥ 4 hours a day, and the south-facing window sill is the best place. Rotate the flowerpot 180 degrees every 10 days to allow the plants to receive even light. When there is insufficient light, you can add LED plant fill light and set the fill light for 2 - 3 hours a day. Nutrient replenishment Hydroponics plants are added with 5 drops of special hydroponics nutrient solution every month, and soil culture plants can be applied with slow-release fertilizer granules. Fertilization should be stopped during low temperature periods (<15 ℃) to avoid the risk of root burning. Root maintenance technology Hydroponics management adopts "three same" water exchange methods: the same temperature (the difference between water temperature and room temperature is less than 3 ℃), the same type (the water is left to remove chlorine for 24 hours), and the same amount (the water volume of 2/3 of the container is maintained). The frequency of water changes in winter is adjusted to 10 - 15 days per time, and replenished in time when the water level drops. When the room temperature continues to be less than 8 ℃, it is recommended to switch to a mixed substrate culture with perlite: peat soil = 3:1. After conversion, the substrate will be kept moist (water content is about 40%), and the transition period can be bagged for 7 days. If the leaf tips appear to be yellow under special circumstances, check immediately: ① Whether the root system is black and rotted ② Whether the water temperature is too low ③ Whether the light is insufficient. Plants with slight frostbite can be pruned on the damaged parts, soaked in warm water at 25 ° C for 2 hours, and re-planted.
Through scientific temperature control, light management and root maintenance, water bamboo can fully maintain good condition in winter. It is recommended to establish a maintenance log to record key data such as temperature and water change date, and adjust the maintenance plan in a timely manner based on the plant's response, so that your water bamboo can survive the winter safely and spring can be full of vitality.
