Duckweed Eradication: Manual Removal Only

Small garden pond, no filter, covered in duckweed. Lilies/iris present. Frogs in spring. Water changes fail. Commercial duckweed treatment failed. Shade from trees. Asks removal & prevention.

Hard Truth

Only 100% manual removal works. Every frond. Best in winter (slow growth).

Options

No fish: Drain, clean completely (or hire pro).
With fish: Net daily in winter. Don't disrupt bio-equilibrium.
Prevention: Reduce nutrients (less feeding, more plants, water changes). Surface agitation helps.

Chemicals fail. Duckweed is the ultimate survivor. Persistence wins.
