Collecting wild plants
Finding plants
If you collect plants from local swamps or trade them with friends, buy from an unfamiliar plant store, please quarantine those plants for a few weeks. Put them in a washtub or kiddie pool with a bit of chlorox in the water.
Parasites, lice, fish eggs, caterpillars and so many other critters can be carried in on those plants and play havoc with your goldfish, your beloved koi and all your aquatic plants.

Patching a pond liner
A strong wind toppled your crane statue into the pond and his beak penetrated your rubber liner. Now what?
Empty the pond to below the hole. Clean the area around the penetration even if you have to scrub it (NO SOAP), rinse it and either wait until it is dry or use a hair dryer. Make sure you are plugged into a GFI outlet for safety's sake. When the area is clean and dry, you can use a tire patch to patch the hole. After all, the rubber liner is made by Firestone out of the same material inner tubes are made of. You can also buy patches or rolls of patching tape that makes it even easier.

Stumps and ponds
The trials of a pond installer:
I will never forget starting an excavation for a pond when I found right in the middle of where the pond was to go, a brand new, just cut, not ground stump. I queried the homeowner who professed complete innocence of how a 24" stump could have gotten dead center in her yard.
I ask all clients ahead of time if I might find any obstacles, like old roots, electrical wires, sprinkler systems, water or gas pipes. She emphatically told me, "No."
So here's this stump and I have to do something. She was grinning, thinking I would have to remove her stump free (I stuck to my estimates.) and she had gotten over. Nope. I dug around the stump, put the liner over it. When the pond was finished the stump hump was dead center. I put a couple of rocks on top and called it an island. I dared her not to like it. She didn't dare not. I got my check and she got a large island. It looked pretty good, but usually when I wanted islands, I put them on top of the liner, not underneath.
Difficult clients are lying in wait out there and all service folks run into them.

Sterile fish?
Question:
Here in California, where the weather is nice all year round. I've been growing Koi for 7 years now, although my fish are healthy and large, I still have not had a spawning. I have heard that my supplier may sell sterile Koi. Has anyone else ever heard of such practice?
Pondlady sez:
I have never heard of sterilizing a fish, but it could be in response to the ever growing ban on keeping koi. When I first heard about it, I couldn't quite believe it, but then we got a news clipping of a fine levied on koi keepers. Evidently the fear is that the koi will get loose and crowd out native species. I'm not sure how little bitty fish would be sterilized, but there could be a way.
Another possibility is that your fish are indeed spawning, but momma and daddy are eating their young.

Gophers and pond liners
Question:
We have gophers!!! They have eaten through my liner. What can I do to stop them?
Pondlady sez:
Put lots of chicken wire down first, and then the roofing felt before you put the new liner in. This works for rats. It should work for gophers.

Plants for your rain garden
And if you don't have a rain garden built yet, here are some plants for wet areas in your garden:
Arrowwood viburnum shrubs
Swamp milkweed, which is a good butterfly plant
Elephant ear plants--this is a tropical plant and is the only one that will not survive in lower zones.
Wild bergamot
Marsh marigolds.
Here in Louisiana our swamps are full of marsh marigolds. I think they are a cousin of hibiscus or mallow because flowers look the same. Louisianians call them marshmallows. Doncha love it?
I have my rain garden planted and it is filling in slowly. Be sure, when you remove the sod, you remove it all. I didn't do a great job, so spent several hours on my hands and knees, sinking into some pretty stinky water getting the rest of the grass out.

Flowers from the garden
With the New Orleans heat upon us, the summer flowers are beginning to put on a show.
Cuphea Torpedo. I think the common name is bat faced heather. Fierce looking isn't he?
My caladium is flowering already
I wanted a grey plant and chose a wonderful aromatic curry plant.
I found some Amazon dianthus. Huge and gorgeous.

Pond on the cheap
You can't skimp on a liner or a pump, but you can build your pond without rocks. Use landscape timbers. Build them up like Lincoln Logs in any shape you wish. You have to use about 16 penny nails, so be prepared to whack at them with at least a heavy roofing hammer. When you have it as high as you wish, line the inside with roofing felt and drop the liner in. Fill up the pond and then use a 1 x 4 to finish the top. If you wish, you can have a waterfall in a corner, but a bubbler in the middle is just as nice.

Leeches
Pond questions - leeches
I'm planning to do a bit of pond cleaning one of these days. I'm not looking forward to it though due to me finding a large number of leaches below one of several rocks in my pond. They're quite small, about 1 cm in length, probably because there isn't much in the pond to suck blood out of. I've got about 20 goldfish in the pond and I've never seen one of them with a leach attached to it.
Is it normal to have leaches in ponds?
Where did they come from?
Is it safe to get in the water without getting some horrible disease from them?
Will the leaches latch onto the goldfish, or will my fish eat the
leeches? (probably both)
Answer:
Leeches or blood worms are harmless and quite normal in ponds, although we don't like them. They can help your pond by eating some of the organic matter trapped in your filter. They will be eaten readily by the fish and are carried in, as eggs, in bird poop. Birds are the carrier host. The type primarily found in our ponds are not the swimming type, so the fish are safe for the most part and they will usually be found in filter matting where the fish can't get them.

Speaking of koi
Koi ponders have learned the hard way that their fish tear up every plant they try to grow in the pond with them. The plant debris clogs up filters and pumps, and even skimmers. It makes a big mess. Koi owners have realized that they had to make a choice between the two and apparently decided on the fish. Most of the koi owners I know have two ponds, one for fish and one for the plants they started with. Koi aren't prima donnas, they are terribly destructive. If they weren't beautiful, and filled with personality, we wouldn't even bother with them at all.

Letters, we get letters
Question about koi pond construction:
I have had several propositions so far this year for a pond. I know where I want it, just not entirely sure how to build it. I want it 5' below ground and 2' above ground, with a viewing window facing the house. I want it right behind my swimming pool so I can almost literally swim with my fishes.
The offers were from two builders in particular, one wants to do gunnite and the other will use EPDM, both will do it over reinforced concrete block. One wants to build a filter shed in the corner of the yard, and the other wants to put a filter "room" below ground next to the house. It is for koi so it will have to have a bottom drain, or two, and the biggest filtration I can afford. I also will, being in Florida which is aka predator heaven, screen it in with my lanai and use the same patio paver blocks around the pond area to match the rest of the
deck area. What do you think? Have I lost my marbles?
Pondlady sez:
I think your plans are over the top!
Oh, one thing. Often swimming pool builders have pond
specialists.
We both know all the problems with concrete, especially in FL
where you are pretty close to sea level. Might want to find out your elevation before doing gunnite.
The filter room below ground can make it difficult to access
when things need servicing.
Answer to pondlady's question:
One gave me a wonderful price for Diamond Brite. What do you know about using this in a pond? I have the same thing in my pool, which is just a finish as far as I know, over concrete construction.
I am above sea level here and the ground is graded so that my property is about 4-5' above the roads and fields around the area. They have to do that because of the septic leachfields I think. Anyway, I am building it 2' above ground to be on the safe side. I have also spoken to the other guy, a pond builder who is expert with koi ponds, to do the installation of the filtration equipment. So these two guys will work together on it to assure me of the best my money can buy.
Pondlady sez:
I don't know Diamond Brite, but think it is just a brand name for a finish, just as you mentioned.
Your pond sounds as if it will be divine. Please send pictures during and after construction.

Pond questions
I have a pond about 3' wide and about 2 1/2' deep- all fish have died in last 2 months- noticed whitish discoloring on the skin developed then they died. Had about 12 or 14. Would a light in pond help?
Thanks.
Pondlady sez:
A light won't do anything for keeping the fish alive. The whitish discoloration may be parasite infestation if it was noticeable before they died. Otherwise, it may have nothing at all to do with the deaths.
My guess is that there was not enough oxygen in the water to
support that many fish. In fact, I doubt there was enough water unless the fish were very small. If you didn't have filtration, that would be another problem. The light will do nothing at all that I know of.
If you put too many fish in your pond, inevitably, you will have a fish kill. It WILL happen.
Thanks.

Questions over the years
Dear pondlady, my fish all died overnight. What should I do?
Pondlady sez: You could try CPR. I'm sorry, I just couldn't resist. First, remove the dead fish and bury them in the vegetable garden, then check your water.
Did you add water yesterday and forget dechlor? That is the most common reason for a total fish kill.
Check these things as well:
Is there run off from a roof or a road or a patio getting into your pond?
If there were children around the past few days, did they throw stuff like an entire can of fish food in the pond?
I would change the water before restocking your pond.

You need submerged vegetation
If you don't have anacharis, cabomba, or one of the submerged plants that gives off oxygen you cannot have a balanced ecosystem. Most of the letters I get ask why fish die, why water turns green, what makes the pond turn into a cesspool. The best answer I have is that there is no submerged vegetation. The fish eat it, fish waste feeds it. It serves as the very lifeblood of the pond.

More than ponds
I use rocks for lots more than ponds. I always use the same kind of rocks, called Arkansas Moss Rock. It's a fieldstone and can be gotten in flat fairly good sized pieces. It's hard to build a waterfall with little rocks. Since we do not grow rocks in Louisiana, we must buy them by the pound. They run about 35 cents a pound and when you need tons, you are talking big bucks.
Often after the pond is in, I will put in a path using more flat rocks. Occasionally building a terrace by placing them piled up against a raised bed to anchor the bed will be an effective accent in an otherwise flat landscape.

pH, important or not
Generally pH is not something we have to worry about in our ponds. Our New Orleans water pH is so high...about 9....and I never worry about it. Sometimes in a new unsealed concrete pond, lime can leach out and pH skyrockets to unsafe levels. There are commercial products you can use to bring it down. Usually they are called pH decreaser or pH down.
BTW, pH is a measure of how acid or alkaline our water is. A high reading or number means alkaline, a low one means acid. About 7 is ideal.
I have never found a pond with a too low pH reading, but baking soda would probably fix that.
When I find a pH level that's too high, I usually use vinegar to lower it. That can make the neighbors think that you are either dying Easter Eggs or making a giant Caesar salad in the back yard, but it will do the trick. Some folks use muriatic acid, but I am too chicken for that.
But usually if you have the proper amount of submerged
vegetation and floating vegetation, the pH will straighten itself out.

Question:
just started up a 100 gallon pond and all but 4 fish died so we drained it and started again , now its doing better but in the last few days its getting darker in color, i know we need some alge but how much is too much? we have 4 koi and i apple snail and a few - 18 small very small gold fish one lillie pad plant and one cleaner fish cant think of its really name , anything you can do to help us , its not easy being green!!!
Pondlady sez:
You have waaaaayyy too many fish. You can't have koi in such a small pond. A koi pond must be at least 3' deep with massive filtration. You can have 3 or 4 goldfish in a 100 gallon pond.
You also need at least 10 bunches of anacharis and 1/2 of the top of the water surface covered with floating plants.
Check my web site: www.pondlady.com, click on resource center for lots more info.
