How to care for hydroponic peace lilies in winter? Do these few things to get them safely through the winter
The peace lily (Spathiphyllum) is a very popular foliage plant. Whether in China or in Europe, it is a popular cultivated flower. Its flower has no petals, consisting only of a white bract and a thick spadix, looking just like a palm. Because its color is white, it was named the peace lily. Peace lilies can be grown not only in soil but also hydroponically. What should you do if your hydroponic peace lily does not bloom? Below, Shuai Shuai will explain the solutions for a hydroponic peace lily that does not bloom!
1. Unreasonable lighting
A flower like the peace lily prefers a cool, ventilated growing environment, and loves to grow under scattered light at an intensity of about 60 percent. But once there is not enough light, the plant will not grow upright enough, the flower buds will not get enough nutrients, and the conditions for blooming will be affected. If the light is too strong, the leaves will easily drop, especially in summer, when the water on the leaves evaporates very quickly; exposed to the sun, they quickly dry out. Flowers are even more prone to scorching than leaves, so this affects the blooming of the buds and may even prevent the buds from forming at all.
2. Inappropriate temperature
Compared with soil-grown peace lilies, hydroponic peace lilies can tolerate high temperatures a bit better, but their tolerance for severe cold is limited. If the temperature is too low, it will cause abnormal blooming or delay the flowering period. So if you want the peace lily to bloom smoothly, you must keep the surrounding temperature above 20 degrees, but it must not be too high either; once it exceeds 35 degrees, growth will stop. It is best to keep the ambient temperature between 20-28 degrees. For hydroponic peace lilies, the temperature must be well controlled.
3. Water quality problems
Using hydroponics places very high demands on water quality. Ordinary hydroponic containers tend to grow algae, which not only makes the ornamental effect worse but also competes with the peace lily for nutrients, and the amount of oxygen consumed in the water increases. If the water is not changed frequently enough, it is unfavorable for its growth and blooming.
In summer, the peace lily should have its water changed once every week. After the Start of Winter, the number and frequency of watering should be reduced, changing the water about once every half month. When changing the water for the peace lily, you only need to submerge one-half of the roots; it must not exceed two-thirds. The other parts can all be left exposed.
4. Insufficient fertilizer
Fertilizer is also very important for the growth of the peace lily. For hydroponic peace lilies, you should buy the culture solution made for peace lilies, or a nutrient solution will also do. Each time you change the water, just slowly pour it in along the way. When it reaches the bud stage, you can water it with monopotassium phosphate, about three times or so.
The above are the reasons why hydroponic peace lilies do not bloom and the solutions. There are still certain differences between hydroponic and soil-grown peace lilies. When growing hydroponically, to retain moisture you only need to maintain the humidity of the culture bottle and the surrounding air. If you usually find that the temperature is too high and the air is very dry, you can spray more water, and you can also spray a little on the leaves, but not too much. Change the water frequently to avoid the production of anaerobic bacteria in the water that would harm its root system.
