Latest Winter Care Methods for Hydroponic Anthuriums

The anthurium is a flower everyone is surely familiar with by now. Like other plants and flowers, winter is a tough hurdle for them. Soil-grown ones are a bit better off; the main issue is that hydroponic anthuriums are very easily frostbitten in winter, and getting them through the winter successfully is a headache that requires the grower's careful attention to get through safely. This plant loves a warm growing environment, so below Shuai Shuai will explain from several aspects how to care for hydroponic anthuriums in winter!

1. Changing the water

Since it is hydroponic, changing the water is certainly very important. The roots of the anthurium are very vigorous and breathe very actively, so when growing in water you must add water at regular intervals, wipe off all the green algae and duckweed from the roots and rinse them clean with fresh water, then pick out the old roots and dead roots and cut them off. Normally change the water once every 2 to 3 days; you must be diligent about changing the water. When the Start of Winter period arrives, you can relatively shorten the watering cycle and frequency, changing from 2-3 days to once a week. Each time you change the water you can also add some nutrient solution; nutrient solution is available on the market now and is not very expensive. After buying the nutrient solution, leave it in the sun first to let the chlorine inside evaporate. Note that for hydroponics you only need to immerse half the rhizome in water; the rest can be exposed outside, and the outside part can carry out respiration better. Frequent water changes have another benefit: they prevent root rot caused by insufficient dissolved oxygen in the water.

2. Light and temperature

Anthuriums are generally best kept on a balcony or rooftop, and during periods of strong sunlight some shading measures should be taken to avoid water evaporating too quickly or damage from scorching by strong light. When growing hydroponically, place it in a good position; a semi-translucent spot is best, and try to create scattered light. In winter the temperature must not drop below 14 degrees Celsius; if it falls below 14 degrees Celsius it will be frostbitten. At this point we can turn on the heating in the room to raise the temperature, or use an electric heat lamp to shine on it and raise the temperature. When using an electric heat lamp, do not place it too close, to prevent scalding the plant and leaves. Keep the air humidity at around 80%; when it is dry, you can use a humidifier or spray some water around the pot with a shower head to increase the air humidity.

3. Increasing oxygen

Compared with hydroponically grown plants of similar types, anthuriums are more prone to root rot, especially when no one has tended them for a long time and the water has not been changed in time. The main factor causing root rot in hydroponics is the dissolved oxygen content in the water. The simplest and most convenient solution is to shake the vase; we can hold the flower with one hand and gently shake the container with the other, and shaking it about ten times or so can increase the dissolved oxygen in the water by 30%. Isn't that simple and convenient? If conditions allow, households can add a little hydrogen peroxide, about 1%, when adding the nutrient solution.

The above are the winter care methods for hydroponic anthuriums. If you can do all of the above, there will basically be no problem getting through the winter. If you are in the extreme cold weather of the north, then we must control the water temperature, because the ambient temperature and the water temperature are different, so the water temperature should be raised to prevent the rhizome from being frostbitten or freezing. Once you notice freezing or clumping, be sure to take warming measures in time, and this way you can ensure the anthurium gets through the winter smoothly.
