Brand new to garden ponds
I've had zero experience with ponds and have a basic question which I
haven't found addressed anywhere online or in a book. Either I'm looking in the wrong places, my question is too dumb, or no one who's written about ponds remembers what it was like to know absolutely nothing about them. My question is this: If, as I understand it, the pond needs oxygen in the water to keep from stagnating and to support fish, and if certain plants are generally used for this purpose, and if one needs a liner in the pond to keep the water from seeping back into the earth, how are the plants to take root? Obviously they can't get any nourishment from the pond liner and would damage it if the roots penetrated it. I'm having a real problem getting a grasp on this concept. And and all help will be appreciated, as I am trying to plan my first pond. |

The plants are put in a pot with dirt, usually heavy clay type, unless they
are "floaters" such as hyacinth or water lettuce - some people put gravel on the pond floor and let them root into it, instead of pots - plant roots won't penetrate the liner (with the exception of bamboo) . The floaters get nutrients from the pond water (helps to clarify it). The potted type get fed from fertilizer you give it, or from the crap collecting in the gravel on the bottom Gale :~) My question is this: If, as I understand it, the pond needs oxygen in the water to keep from stagnating and to support fish, and if certain plants are generally used for this purpose, and if one needs a liner in the pond to keep the water from seeping back into the earth, how are the plants to take root?

And and all help will be appreciated, as I am trying to plan my first pond. You'll get lots of answers but let me try a starter. Many pond plants do fine taking nutrients from the water column. I had my hardy water lily in a pot, it outgrew it, I split it several times, tossed it in other ponds and the "babies" are doing fine without being potted. Then there are the floaters, which don't need to be potted although some can be. Anacharis is one that does well in my ponds, as well as hornwort. I think I have some Parrot's feather growing in and out of pots. Some people will argue your fish will eat the plants, which is true, but if you have goldfish (not koi) and a LOT of plants compared to fish (as I do), there should be no problem maintaining plant stock. Heck, if you lived near me I could give you a lot of excess I typically end up dumping on the compost pile! BTW one of my ponds is "in-ground", i.e., a liner on top of clay. The other two ponds are stocktanks - hard plastic. All pond plants I use work well in all my ponds. Gail near San Antonio TX USA |

You have good answers.
Our main pond is cement. No root penetration! Plants float, grwo wild on the bottom or are in pots. Fish waste provides nutrients. Jim |

If you were to toss some cuttings of oxygenating, submerged aquatics on a bare, lined pond they would float about. They might get mushy with surface coating algaes, Winter freezes turn them to mush in cold climates where they freeze in ice
Given a longish growing season, they would try to grow, mass up, and extend their stems downwards, putting out roots.... Anacharis can reach four, five, six feet downwards, their roots would intermesh with leaves and pond debris, they would anchor themselves... over time their roots would make a living blanket at the pond bottom. Cabomba likewise, will push stems downwards, putting out roots whose sole task is to knot, mesh, grip anything they can, if only itself and other roots.... Hornwort won't, it does not make roots, but it would send its stems into deeper water. Winter freezes encourage it to break into fragments which sink to the bottom of the pond, to restart when next growing temps warm the pond Many aquatic plants are very adaptive, according to the growing conditions that they find themselves Regards, andy http://www.members.aol.com/abdavisnc/swglist.html http://i93.photobucket.com/albums/l42/adavisus/

You all seem to be forgetting that a plant gains it's primary source of nutrition by fixing co2 into sugars using energy from the sun. The sugars are used as building blocks to grow, and fuel for other processes. It's roots take up water and molecules such as nitrates, phosphates and metals to help build proteins for specific processes (such as photosynthesis). Luckily for us, fish crap out those kind of goodies continuously. People often make this same mistake about carnivorous plants, completely forgetting that they are green and photosynthesise like any other plant to generate their own food. In their case, insects provide the molecules that don't exist naturally in their soils. -- DavidM www.djmorgan.org.uk |

Obviously they can't get any nourishment from the pond liner and would damage it if the roots penetrated it. Garden ponds usually have liners to hold the water. There are more than one kind. The preformed plastic was the one I started with, but soon learned about 40 mil EPDM (like rubber) and I prefer that type now. Without a liner the pond would continually remain cloudy, since goldfish and koi were both bottom feeders and suck up dirt and spit it out looking for food in the bottom mud. Water can be oxygenated by spraying it into the air or dropping it from a water fall, flowing it down a stream or even pumping a stream through the water generates some oxygen. Mud bottom ponds (usually measured in acres) are often oxygenated by spraying the water into the air and let it fall back into the pond. Plants during daylight hours absorb carbon dioxide and release oxygen, but at night when sunlight is not available for plants to use to make plant food, the plant takes oxygen from the water and releases some carbon dioxide. This doesn't mean that plants aren't beneficial, they are and more ways than just oxygenating the water. They absorb fish wastes as plant nutrients helping to clean up the toilet bowl existence of the fish pond. There are many plants that fish keepers use, but the most popular are probably fast growing floaters, like water hyacinth, water celery and several others. That is not to discount the value of many others that require an anchor to keep them in place. I have Louisiana iris anchored to cinder blocks, their roots attach themselves to the heavier blocks and keep them upright in winds. Rush and canna lilies also work well as cleaners in some ponds, but the canna grow tall and blow over in the wind in my pond. I don't consider my potted lilies an oxygen producing or cleaning asset. I fertilize the lilies so they will bloom well, look good and shade the pond as well as providing a cover for the fish. I feel I should point out the fish will root around in plant pots and vacuum the dirt up blow it out and leave the water cloudy if the pot surface is not covered with stones the fish can't pick up and move. -- Hal Middle Georgia, Zone 8 http://tinyurl.com/2fxzcb |

Many years ago I visited an exhibit sponsored by some agricultural firm at DisneyWorld's EPCOT where they were growing corn? in nothing but air and misting water. I remember being impressed by the huge size of the plants and at the massive root systems just hanging there. Some on this list may remember (or even still have some in their basement) as this is a favored way to grow pot. Dirt is simply a mechanical device to hold the plant in place, insulate the roots from freezing or cooking, and provide a holding place for the nutrients to reside while waiting for water to transport them to the roots. If you anchor or allow the plants to float, have moderate temperatures, and the water is already full of nutrients, Bob's your uncle. BTW, how do bamboo roots pierce the liner? Do they have barbs?

My question is this: If, as I understand it, the pond needs oxygen in the water to keep from stagnating and to support fish, and if certain plants are generally used for this purpose Not generally in a man made small pond. We use waterfalls, airstones and such. and if one needs a liner how are the plants to take root? Baskets lined with weed fabric holding soil, the plant, & rocks on top to keep the fish from rooting out the soil while looking for worms. Obviously they can't get any nourishment from the pond liner Most pond plants get their nourishment from the water. Many don't need pots, they just float. Grasses, like hornwort & anacharis will adhere to folds in the liner all by themselves. I am trying to plan my first pond. It would help us if you would explain what your plans are, advice differs for a koi pond, a goldfish pond, or a water garden with just small fish to eat mosquitos, etc. Size? Location? Power sources.... Depth? ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |

Chip Take a look:http://bambootexas.com/YearRound.htm And those spikes are HARD. ~ jan ------------ Zone 7a, SE Washington StatePonds:www.jjspond.us I believe from reading the link that that bamboo is not the same variety as pond bamboo. Bamboo and many rushes have strong pointed roots which can and do poke holes in pond liners. If you use them make sure to plant them in HOLELESS pots that are very large so the root don't over grow the pot in a season or two. Using a mix of heavy garden soil or black top soil mixed with sharp builders sand make repotting and dividing water plants much easier. Small ponds are best for goldfish as the recommended size for koi is 500- 1000 gallons per full sized koi. Pumps, filters, skimmers and air pumps all add oxygen to the pond. Mosquitoes breed in stagnant water. fish love the larvae. Good luck, Gail |

Small fish to eat mosquitos. I am mostly interested in cultivating frogs - small green frogs - and providing amusement for local birds. If you want frogs, don't put in fish, they eat frog spawn. At least tree frog spawn. I'm not sure if anyone else has luck growing frogs with fish in the pond? very small pond, definitely under 1k gallons. I am thinking of putting it in the lowest part of the property and letting it collect rainwater. Easy maintenance, hopefully. We generally recommend not letting run off flow into ponds due to all the nutrients and then green water it produces. It is one of the biggest no no's in the books, don't put it in the lowest part of the garden for this reason. Plus, rain water is acidic, but frogs won't care. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |

I always had toads spawning in my well stocked fish pond - but I always had Green Frogs, and I can't say I often had successful spawnings (I certainly found occasional frog tads, but not by the hundreds like the toads). -- derek |
