This is the main fertilising method I use for pond plants grown in pots or directly in pond soil.

I mix blood and bone fertiliser with clay-based soil, roll the mixture into small balls, and let them dry and harden completely. Once dry, the balls become firm and slow-release.

To use them, I push one ball down into the soil near the roots of the plant. This allows nutrients to reach the root zone gradually without clouding the water.

You can make a batch of these fertiliser balls at once and store them in a sealed container. They will keep for months or even years and can be used as needed. They also work well in other potted plants, not just ponds.

Banana peels are an easy way to reuse kitchen waste and feed pond plants naturally.

They break down slowly in soil and release potassium and trace minerals over time. I chop the peels into small pieces and push them below the soil surface in the pot so they can decompose without floating in the pond.

This isn’t an instant fertiliser, but it supports healthy leaf growth and flowering over time.

Crushed eggshells add calcium and organic matter to pond plant soil.

I rinse the shells, crush them finely, and mix them into the soil or push them gently into the top layer. Eggshells break down slowly, so they work best as a long-term soil conditioner rather than a quick feed.

They’re a simple way to recycle waste while supporting healthier plant growth.
