Dealing With Weeds in Ponds

Pond Weed
Pond Weed

A small wild life pond doesn’t have to be weedy in either sense. This pond in our park for example is a fairly large size. However as you can see it is ‘Weedy’ in the gardening sense.

Removing Blanket Weed

  • Oxygenating plants are the best and organic method but may fill half the pond.
  • For a small pond you can try the winding it around a stick method but roots regrow and small critters may be thrown on the compost heap with the weed.
  • Sun causes growth of blanket weed and a covering of water lilies will help keep it down
  • Hydrogen peroxide inhibits all algae growth and this can be created organically using straw bales made from Barley – Put some in a stocking for a smaller pond or try a chemical concentrate
  • UV filters are expensive but if you want to be sure to see your fish hang the expense.

Algae and Other Pond Weeds

  • One easy way to get rid of an algae mess is to dredge or empty your pond. This is obviously impractical in many circumstances.
  • Increased circulation in the pond will stop algae.
  • Grass carp love to eat pond weeds and plants whilst young grass carp will feed on algae.
  • Biocides and special herbicides can also control pond weed
  • Some weeds can be lifted out or twisted around a stick and pulled out. Leave on the side to let creatures return to the pond before composting.
  • Cover the pond so leaves do not accumulate. They will rot and gases given off will damage oxygen levels for fish.
