Solutions for Yellowing Leaves of Pennywort in Winter

Pennywort (Hydrocotyle vulgaris) is an ornamental plant with very high ornamental value, and its planting area in China is also very large. When growing pennywort, it is affected by weather changes. Especially in winter, various problems often occur easily. Yellowing leaves in winter is one of them, so what should be done when pennywort leaves turn yellow in winter? Below, the editor will give you a brief introduction, let's take a look together!

1. Light Control

During its growth, pennywort has a relatively high demand for light. Sufficient light is needed to ensure healthy growth of pennywort, and in winter, not only is the natural light duration short, but the light intensity is also relatively low. So at this time, pennywort's demand for light is even greater, therefore insufficient light in winter can very easily cause pennywort leaves to turn yellow. So in winter we should pay attention to creating a bright light environment for it, ensuring pennywort can fully access sunlight, reducing the phenomenon of yellowing leaves in winter.

2. Reasonable Water Changing

Pennywort is an aquatic plant, and during normal cultivation, water changing work needs to be done well. Many people think that in winter, the temperature is relatively low, so the possibility of bacterial growth is relatively small. But note that if water is not changed for a long time, the water quality will gradually become turbid, which has a very large impact on the roots and easily causes leaves to turn yellow. So in winter we should also pay attention to doing the water changing work well, observing changes in water quality, and generally changing the water about once every two weeks. When changing water, also pay attention to the water temperature, which must not be too low.

3. Temperature Adjustment

In winter, temperatures are relatively low. And pennywort's temperature requirements are relatively strict. If in winter the environmental temperature for pennywort is relatively low, especially if it is below 5°C for a long time, then pennywort plants are very easily frostbitten, resulting in yellow leaves. So in winter we should pay attention to controlling the temperature well and doing good insulation work. Keep the temperature above 10°C, and if conditions permit, add heating equipment to ensure pennywort survives the winter safely. Reduce the phenomenon of pennywort turning yellow due to low temperatures.

4. Reasonable Fertilization

Although pennywort's growth amount in winter is relatively small and its nutrient demand is also relatively small, we should still pay attention to doing fertilization work well in winter. If pennywort lacks nutrients in winter, it is very easy to develop nutrient deficiency yellow leaves. At the same time, also pay attention to controlling the fertilizer amount well, and do not fertilize too much, as excessive fertilization easily leads to fertilizer burn, and also easily causes fertilizer damage. So we should control the fertilizer amount well and fertilize reasonably according to pennywort's growth condition, satisfying pennywort's growth nutrition while avoiding fertilizer damage caused by excessive fertilization.

The above is a brief introduction to what to do when pennywort leaves turn yellow in winter. That's all for today's introduction. This article is for reference only, and we hope it can help everyone!
