How to prune broad-leaved pondweed

Autumn for die-back removal; summer for thinning if overly dense. Rake or pull out excess surface growth by hand or with an aquatic rake. Remove dying autumn foliage before it sinks and decomposes. Leave some cover for pond wildlife.

Annually in autumn; summer thinning as needed. Broad-leaved Pondweed needs little pruning but can be thinned if it becomes excessive. In autumn, remove yellowing and dying surface leaves and stems to reduce organic matter decomposing in the pond over winter. If growth becomes too dense in summer, remove some stems and floating leaves to maintain open water areas for other pond life.
