Reasons for Yellowing Leaves on Nasturtium and How to Fix Them

Generally speaking, the reasons for yellowing leaves on nasturtium are many-sided; water, fertilizer, light and pests can all be causes, so when flower lovers read this article they should judge the reason for their own nasturtium's yellowing leaves according to their own actual situation.

Below we will go through each cause of yellowing nasturtium leaves

1. Watering: after nasturtium blooms, watering should be reduced to prevent excessive growth of the stems. If watering is excessive or drainage is poor, the roots are prone to rot from dampness; in mild cases the leaves turn yellow and drop, and in severe cases the whole plant wilts and dies. (If water accumulates in the potting soil, it will cause the leaves to turn yellow)

2. Fertilizing: needless to say, no matter what plant it is, over-fertilizing has the same effect, and it is also fairly easy to judge whether fertilizer was applied recently.

3. Light: this cannot be discussed in terms of light alone; it is better to speak of seasons. Nasturtium is a perennial plant that fears both cold and heat, and goes dormant in summer. It can be placed in a cool, ventilated spot, with fertilizer stopped and watering reduced, and during the plum rain season do not let water accumulate in the potting soil. Doing these things basically gets it through the summer. (Simply put, nasturtium fears heat, and especially in summer it easily develops yellow leaves, which is also due to the difficulty of getting through the summer)

4. Pests and diseases: if nasturtium has pests such as red spider mites, this will also cause the leaves to turn yellow. The way to judge is to look for spider silk on the leaves, or for insects on the underside and the like (look carefully)
