Water lillies in a pond during the month of April.

Feed the Plants

Larger aquatic plants, such as water lilies, will really benefit from a slow release tablet food. I've used Lily Grow in the past which is a pond plant fertiliser and its much needed nutrients are sure to promote healthy growth.

Divide Overcrowded Plants

When the water temperature has warmed it's a good time to replant water lilies. If you didn’t get a chance during March, you should also divide any overcrowded pond plants such as marginals and cut back oxygenators too. 

New Plants

Take the opportunity to introduce new marginal plants in shallow water, Marsh Marigold or Water Forget-Me-Not are favourites. This will give them time to establish before any fish are added.

Tackle Algae Early

Blanket Weed, a hair like stringy algae, and Duckweed, with its thousands of tiny leaves, need to be tackled earlier rather than later. Try and remove as much as you can and then use one of the many water treatments that are on the market. Other problems, Green Water comes to mind, can also be treated.

These jobs are all dependent on the weather. So if it continues to be cold and you’re still finding ice on the pond, be patient and wait until warmer weather arrives.
