Lake Bottom Blankets
A sunlight barrier that kills aquatic weeds
Lake Bottom Blankets block sunlight to aquatic weeds, which starves them to death because they can’t photosynthesise food.
- Low cost: one of the lowest cost ways to control aquatic weeds.
- Chemical free: a 100% natural solution that doesn’t require herbicides.
- Reusable: Treat multiple areas in your dam by moving the blanket (after the weeds have died).
- 100% effective: guaranteed to kill weeds in weeks.
How it works
- Step 1: Unfold the blanket and thread rebar (purchased separately) into each end. This will anchor the blanket to the dam floor.
- Step 2: Place the blanket over the area you want to remove weeds from (e.g. swimming area). We recommend using the white side up if you want to know where the blanket is (e.g. to prevent boats damaging it) or the black side up if you want the blanket to be invisible underwater. Wait at least 4 weeks.
- Step 3: When the weeds are completely dead, move the blanket to the next problematic area or remove the blanket from your dam altogether.
