There’s nothing people enjoy any more than a bit of plant killing, especially in their pond, or in some cases the fishpond where it would make major issues for the fish as well as you. Fish don’t enjoy moving through a huge underwater forest any more than the rest of us, so it is best to control the plants on the bottom of your pond, before one of them turn into that man-eating plant from Jumanji.
An overgrowth of aquatic plants may cause problems all the way from watercraft motors being clogged, to poor results while fishing, to children experiencing a horrible time trying to swim through the pond. None of those are things you want, so it is better to destroy the source of the issue before it starts.
You have a couple choices available to you, options which go from biological control, meaning the use of fish that naturally govern the plant populous, to covering your entire pond with plastic…that seems a pretty dramatic measure, but hey, do whatever suits you.
So let us review a few of your options, and after that you may choose which one is best for your situation, but remember that these are only a very small selection of options, and you should consult with different pond owners, or experts to discover each and every method available to you.
Harvesting – Getting rid of the plants through manual labor, is definitely a great choice. However, if the plant isn’t on the shoreline, or isn’t|is not on the top of the pond, you may find yourself investing in some diving equipment to swim down to the bottom without suffocating. If you do not know the dynamics of diving, or can’t stop breathing for a long time, it is encouraged for you to consult the professionals. As a matter of fact, there are companies that work to clean the bottom of bodies of water, so you will be pretty well off.
Chemicals – There are a lot of chemicals at your disposal to get rid of this annoying plant life. A few chemicals are Fluridone,2,4-D, Glyphosate, Diquat, Endothall. Naturally though, it is not encouraged for you to use any kind of herbicide or chemical to kill off your plant life, which is not unlike the reason it’s never advised you toss a live wire into a pond to capture the prize fish. Utilizing herbicides may be deadly to fish, as well as any other life forms you may have within your pond. Use such things carefully, or even better, don’t utilize them period unless you absolutely have to.
Dye – You can purchase a wide range of chemicals that will tint the color of your water, and therefore reduce the volume of sunlight for any aquatic plants. It’s better to do this in the early spring for best results.
Lining – Lining the bottom of the body of water with a type of plastic is also an choice, as that will halt the growth of any sort of water plant life. Keep in mind that it can become costly, so consider the size of the pond, in addition to how much plastic that you will need. Naturally that is a good option for compact fish ponds, but perhaps not so much for a whole lake in the backyard.
Remember that there are tons of methods to halt plant life from invading your water, and to discover the method that is good for you, consult a specialist or talk to different pond keepers.
