Why is my marsh plant turning yellow?

If you are wondering why your marsh plant is turning yellow, please mind that, like everything else, leaves are born, live and die.

A yellow leaf means that it is at the end of its life and that soon it disappears completely.

Marsh plants do not like temperature changes. Often, immediately after the summer heat peak, you will notice more yellow leaves than usual, which will however be replaced by new leaves in a short time.

If you have had the plant in question for more than a year, you should re-fertilize it, especially if you have a pond with clean water (without fish, where there are few dissolved organic substances in the water).

If the basket is saturated, the plant may need to be divided and repotted, as well as re-fertilized. You understand this if the plant has been in the same basket for years, so a hard and compact clod has formed, and the plant produces small leaves and few flowers.

In autumn, on the other hand, plant growth is greatly reduced, so you will see many more yellow leaves.

You can divide and repot marsh plants at any time of the year without any problems. Only bulbous plants, i.e. sagittarias, should only be divided and repotted in spring.

You can find more detailed information on how to grow aquatic plants and obtain a balanced pond in the Guide to Growing Aquatic Plants and in this free Video Course!
