How often does common water hyacinth need pruning?

Regularly throughout the growing season to control spread. Water hyacinth is a fast-spreading free-floating plant — in many US states it is invasive and legally restricted. Pruning means regularly thinning the colony by physically removing excess rosettes and cutting out dead or yellowing leaves. Without active thinning it can blanket a pond surface rapidly, depleting oxygen for fish and other aquatic life.
