What to do if the leaves of the pennywort plant turn yellow in hydroponics during summer
A comprehensive explanation of what to do if the leaves of the pennywort plant turn yellow in hydroponics during summer, and a detailed solution for the yellowing leaves of the pennywort plant in the introduction of green plants and flowers. Here is the detailed introduction.
The pennywort plant has a compact growth habit, with round and chubby leaves resembling ancient coins, which look very adorable. Many people enjoy hydroponically growing pennywort, simply by placing it in a beautiful vase with clean water, which is convenient for maintenance and has high aesthetic value.
However, some flower enthusiasts have recently reported that during the process of hydroponically growing pennywort, the leaves often turn yellow, although it doesn't lead to death, it seriously affects the appearance. Today, I will introduce in detail the reasons for the yellowing of hydroponic pennywort leaves in summer and the solutions.
1. Water Quality Issues
The roots of hydroponic pennywort grow in the water of the vase, and the quality of the water directly determines the growth vigor. In hot summer weather, pennywort grows rapidly, but various bacteria are also very active. If the water is not changed for a long time, the clean water in the vase quickly becomes very cloudy, and even green algae may grow. The roots of hydroponic pennywort are nurtured in污水, and the roots become damaged and unable to absorb water normally, causing the leaves above to gradually turn yellow.
Solution
Pennywort grows well in water with a pH between 6.5 and 7.5, which is neutral or slightly alkaline. Tap water is slightly alkaline and is suitable for growing pennywort. Moreover, tap water has been disinfected, with very few bacteria, which can keep the water clean for many days. You can use tap water directly. Whenever the water in the vase becomes cloudy, you should change the water for the pennywort immediately.
2. Insufficient Light
Pennywort loves sunlight and cannot do without light all year round. If hydroponic pennywort is kept in a dark corner of a room or in a bathroom for a long time, the leaves cannot absorb enough sunlight to convert into energy. Over time, the leaf color gradually fades, and severe cases will turn yellow.
What to do if the leaves of the pennywort plant turn yellow in hydroponics during summer
Solution
Pennywort is highly tolerant of sunlight, and it doesn't need to be shaded even in the hot summer days. As long as there is no lack of water, there is no need to worry about it getting sunburned. Place the hydroponic pennywort in the best-lit area of your home, and if possible, keep it outdoors in the sun. The more it is exposed to the sun, the brighter the leaves will become.
3. Lack of Fertilizer
The growth rate of pennywort is closely related to temperature. It is a warm-loving plant, and the warmer the weather, the faster it grows. Pennywort grows very fast in summer, with new shoots constantly emerging from the base. These shoots need to grow into large leaves, which require not only light and water but also nutritional support. Soil-grown pennywort can absorb nutrients from the soil, while hydroponic pennywort can only absorb nutrients from the water, which has very few nutrients compared to soil. When the nutrients in the water are insufficient, the plant does not get enough nutrition, and the new leaves will also turn yellow.
Solution
Because the nutrients in tap water are too few, we must fertilize and supplement nutrients for the hydroponic pennywort regularly during the growing process. Unlike soil-grown plants, hydroponic pennywort cannot use ordinary fertilizers, only special nutrient solutions for hydroponic plants. Add the nutrient solution to the water according to the instructions, usually once every 15 days or so. Pennywort is not tolerant of concentrated fertilizers, so use a small amount of fertilizer each time.
