Aquatic plants do not actually need fertilizer because the garden pond contains natural fertilizer. However, some pond plants need a little boost.
It is common knowledge that plants in the garden need to be fertilized from time to time. With many specimens, optimal growth and abundant yields are only achieved through the supply of nutrients. But what about aquatic plants? Do you really need to fertilize aquatic plants? This is where opinions differ between pond owners and hobby gardeners. While a small part is clear about fertilizing the aquatic plants, the majority is against this measure.
Yes, you can also fertilize aquatic plants, but if aquatic plants are over-fertilized, rotting or burning is the order of the day. Apart from that, too many nutrients remain in the water and the floodgates are then wide open to algae formation. The fertilization of the water garden is not based on acting, but only on the reaction, in which only specific and sparing nutrition is introduced into the natural cycle.
Aquatic plants only fertilize in an emergency
If the plants are placed in the pond, no fertilizer needs to be added. It only gets critical when the plants show the first signs of deficiency, such as a yellowish color and poor flowering. Nutrients can then be added, provided that the deterioration in the condition of the plants has nothing to do with the stocking of the pond being too dense. But beware: pond plants that discolour do not necessarily have to be diseased. Aquatic plants take on a reddish-brown color, especially in autumn.
If fertilization is required, this is done using a fertilizer cone or a fertilizer tablet that is pressed directly into the soil. Direct fertilization via the water is also possible if necessary. It is better to fertilize with water, as this is not as effective and the fertilization is gentler.
