Lake weeds can grow very fast and can cover the water within a short period. Some plants such as duckweed are very hazardous, and their growth poses a danger to the aquatic life. Dangerous weed species can interrupt the regular ecosystem as well as lowering the aesthetic value of a region. Below are some useful methods of controlling notorious weed species like duckweed.
It's advisable to initially control the growth of aquatic weed by taking preventive measures like lake rake. Aquatic weeds will not spread quickly on steeply pond banks, but they can thrive very well in shallow margins to deep waters. It's therefore sage to ensure your pond banks are not shallow enough to encourage the growth of the weed. If the depth of the pond is three feet, then the bank of the lake should be four feet. Deeper pond bank will suppress the growth of aquatic weed.
If the weeds have already grown, you can pull out the weeds using your hands. If the weed has already spread in the water making it difficult to pull with hands, then you can remove it using the underwater cutter. Water cutters are very convenient when it comes to cutting annoying pond weeds such as milfoil and water lilies. One disadvantage of cutting weed underwater is that one the weed is cut it lies down on the waterbed and some weeds are very irritating, and they can reproduce from tiny pieces and regrow again within no time.
If the weed is excess, you can use herbicides such as aquacide to kill the plants in the pond. herbicides which are ideal to be used in water comes in different varieties such as pellets, granular and liquid herbicides. Herbicides are chemicals, and you should read instructions carefully on how to use it without killing aquatic life in the pond. Exposure of excess chemical may result in harmful effects of other water species. You may consider treating the lake into potions. One uses the chemical on each portion at a time and eventually, the weeds will be eliminated using this product.
Sunlight is essential when it comes to growth of all plants. If sunlight fails to reach plants during their growth, then the plants cannot thrive. You can opt for benthic barrier also known as the bottom screen which covers the sediment preventing the sunlight from reaching the aquatic plants hence compressing them. Weeds that grow in masses are challenging to be handpicked therefore the use of benthic barrier is the best option.
