Top it up

When the water warms up a little, it is normal for the water to turn a little green. But, if there is a good balance of plants and water this can soon become clear again. If your pond doesn’t have a filtration or pump system, it’s even more crucial to keep on top of your pond care.

Freshen it up

They can be removed by hand or by twirling the algae out of the pond using a long bamboo cane. However these fixes are only short term solutions, so it’s best to assess the conditions of your pond. and consider how to improve it. You’ll then decrease the likelihood of algae growing.

Pick out plants

Oxygenating plants like water crowfoot are essential in ponds to keep the water clean. But sometimes they need a bit of maintenance.

Weed between marginal plants that are grown around the edge of your pond, just like you would in the beds and borders. Take out any unwanted plants or shoots. It may be easiest to remove the containers that these plants are growing in to give you the best access. They can then be weeded or divided and replanted back in the water.
