Pond in a Sugar Kettle

Here in Louisiana we grow sugar cane. In long ago days, the sugar was extracted by hand and the resulting liquid was put into kettles, sometimes as large as 8 feet across. Horses or people then walked round and round the kettle pulling or pulling a large mixer to turn the sugar into syrup. Since this method is no longer used, we have many huge cast iron kettles around. Some people have turned them into ponds. Gotta be one of the great recycling ideas. It is so popular that you can now buy fiberglass 'sugar kettles' and have a pond that you can move and care for easily.

Pond letters

Dear Jan,

I just started digging out a spot for my water garden.
I got it about a foot deep before it started to rain.
It has since filled with rain water, about 10 in deep.
it's been almost two days and it still has 4 in of water in it. I was planning on using an epdm liner, Do i need to put a drainage system under my pond, so the rain water doesn't lift it out of the ground?

ps can goldfish live in a mud hole?

Pondlady sez:
Goldfish can probably live in most any water. I know that there were goldfish in my abandoned pond post Katrina that lived there for over a year with hardly any water in the pond, no pump, but much anacharis. But I would not recommend keeping goldfish in a mudhole or in an abandoned pond.

It sounds like you are near sea level, so I would not put a drain in because ground water will come up through the drain.
Be sure to make your pond at least 4" above grade so the ground water will be pushed down and stay where it belongs.

Dechlor

Please, please keep a bottle of dechlor on hand. If you never need it, that's wonderful, but here's why you need it. You turn the water on to top off your pond. It's going to take a bit of time, so you decide to fold the laundry while you are waiting. The phone rings. You chat with your friend for a few minutes. Then you remember you have to get some bill payments in the mail, so you hop in the car to drop them off at the post office. While you are out, you decide to pick up a few things at the grocery store and pick up the dry cleaning. In the cleaners, you talk with the clerk about the weather for a few minutes, get back in your car and see you need gas, so you stop to fill up the tank. You get home and for the life of you, you can't figure out why the driveway is flooded.
Suddenly it dawns on you. You rush to turn off the water and see your fish lying at the bottom of the pond not moving. If you have dechlor in the house, you can probably save those fish.
Whew, aren't you glad you have some?

Pond Pump Killers

The pond pump uses an impeller, a small reverse propeller, to take in water. If a pump burns out, most of the time, it is the impeller that gets clogged, makes the pump work too hard and burns it up. Most pumps have a safety mechanism built into them that shuts the pump off when it gets too hot and lets it run again when it cools off. So if you notice your pump working intemittently, know you have a problem. UNPLUG the pump and check your impeller immediately. It is usually on the bottom behind a screen that you can easily detach. Chances are you will find gunk in there. It may be too late to save the pump, but it is worth a try. Wash the pump with a strong hose stream from the outgo end. That will help get the junk loose. If you can't get to the impeller with your hand, use a screwdriver to start it moving again, much like you use a broom handle in your garbage disposal.

To keep junk out of the impeller, protect it with a pump prefilter and clean it often.
Most pumps come with a prefilter, often a small cylinder filled with foam rubber that screws on the impeller end of the pump, other times, the pump will arrive already in a box of foam rubber. Pondmaster pumps, a favorite of mine, arrive complete with a black box and layers of prefilter material.

Pond pumps

We rarely consider utility pumps as pond hobbyists, but I think it is useful to know they exist and wen to use them. When I was actually doing field work, I used to clean 200+ ponds yearly. To get this done quickly and efficiently, I used a bright blue, squatty Little Giant pump




These pumps have a cast iron housing and will suck up solids up to 2" in diameter and at 4000 or so gph, they can empty a pond in short order. You must be careful or they will suck in fish. I would never use them as a regular pond pump because they use much electricity, but for pond cleanouts. Nothing can beat them. They are tough, and reliable but really heavy.

Around the pond

My pond is built, now what? Until we landscape around the pond we have nothing but a rock pile. I try to use soft plants, plants that mound up and trail over, often into the water.

There certainly are no set-in-stone rules about what to plant around the pond. For low maintenance and to keep the raccoons out, use asparagus fern. For a tropical feel, use Russellia, variegated ginger, giant bird of paradise. For an Asian feel, use juniper prostrata and an ornamental grass like purple fountain grass. If you are in the shade use ferns. If you love the ferny look but are in sun, use dill, yarrow, and other herbs. Ornamental potato vine works well in sun or shade, so does bleeding heart vine. Let it trail over the waterfall.

Cannas can work in the water and out for a great broadleaf look. Louisiana Iris can also work in and out for a strap leaf addition.

The picture above shows how many plants work around the pond. This was my pond in New Orleans after a very long time of no maintenance. Somewhere back in there, a water flows.

Above ground ponds

I built this pond at the end of a driveway in front of the back porch. I talked for a long time to convince the client not to build a pond on the driveway, but could not talk her out of it. So on the driveway, it went. I used cinder blocks for a strong wall, dropped the roofing felt in it and then the liner. After filling it with water, I started covering up the cinder blocks with Arkansas Moss Rock. For what it is, it turned out OK. I put lots of soil in between the rocks, so I could tuck plants in there.

It's getting cold!

Even down here in New Orleans, it's getting chilly. Mornings are down in the 50's and afternoons are reaching the 80's. I know that sounds warm to you Northerners, but we know that winter is coming, or for some of you, it's here. Time to stop feeding your fish or maybe you already have.
Some of you take your goldfish and koi inside for the winter. If you do, make sure you have adequate filtration and aeration in your inside tank. And just as important make sure it is large enough for all those fish. Don't forget that the fish, because they are most likely in a smaller amount of water, need to have the filter cleaned more often than when they were outside I doubt you have a tank the size of your outside pond in your house, so be sure to keep that filter clean. And never, never turn the pump off. Fish are oxygen breathers just like we are, so make sure they have enough to breathe. If you see fish gasping for air at the top of your inside tank, they are not getting proper aeration. If your power goes out, you must make sure the fish tank water is moved sufficiently to keep oxygen dissolved in it. Just think, if your house heating system goes out because of loss of power, you can keep warm squeezing the turkey baster in the water until the power returns.

More about pumps

There are so many kinds of pumps for the pond: Electric motor driven, magnetic drives, solar driven. There are submersible pumps; we use them most often, but sometimes the same pump can use used out of the water. It's called an in-line pump.

They all do the same thing. An impeller (sort of a propeller in reverse) sucks water in one end and blow it out the other. We use them to power our waterfalls, make our spitters or fountains work or just aerate the pond. In terms of expense, motor driven is most expensive, usually costing about a buck a day to run 24 hours, mag drive a bit less and solar, of course, costs nothing. The solar technology is just now coming into its own, so those pumps would be my choice. Oase is making a line of solar pumps that has a 2 year warranty, a year more than most pumps



I will try one next time I need a pump.

How much does it cost to run a pump?

Electric costs are easy to compute. I am often asked how much it costs to run a submersible pump and if there is a difference between brands. I will use the example of a 100 watt light bulb and a utility cost of $0.08 per KWH. A KWH is a kilowatt-hour or, 1,000 watts used for 1 hour. A 100 watt light - .1 kilowatt or .1 KWH = less that 1 cent per hour.

• Find the actual wattage used by the motor. (If the actual amp draw is not available, estimate by using the full load amps plate.)

• Watts = volts x amps for single phase motors. The light bulb has an amp draw of 8.7 x 115 volts = 100 watts.

• Compute your cost per month by multiplying the KWH x 24 (hours used per day) x 30 (days used per month) x cost in KWH (to find the actual cost look at your last power bill and divide the total power charges byt KWH used).

Pond electricity

If you have a
pump


or

lights


in and around your pond, you must connect your cords into a GFI outlet. Some folks call it a GFCI. It is a Ground Fault Interrupter and has the capacity to cut off power instantly if it gets wet. If you are in the water or holding the cord when water comes in contact with electricity, you will realize the GFI was the best thing you had installed. Most construction codes call for them, but oftimes outside outlets do not have them. And in older homes, you won't find them either. If the GFI happens to get wet accidently, you must push the red button on the outlet to reset it. Have your electrician install them whenever water is near. You won't regret it. Water and electricity don't mix. Ever!

Cooling down

For the past three days, I have awakened to cooler weather. Don't tell me fall has finally arrived in New Orleans. Now we are forced to do the fall pond tasks we have been putting off. Clean that pump filter; it needs it. Cut back those plants before the water is so cold you can't stand to put your hands in it. Use a net to get the debris out of the bottom. Leaves are turning color now and will fall into the pond in a few days. Put netting or some other cover over the pond to catch them. It's easier than getting them out of the water later.

Here are some great tools to help you get those jobs done

A quick fish note

Fish can get sunburned. Don't let that happen by providing shade for them to hide under. It also is cooler in the summer and gives the fish a place to hide when predators arrive.

Fall color

Here in the South, if we are lucky enough to survive the summers, we can have color in our gardens and around our ponds throughout the fall and winter. I like to use snapdragons and petunias. Pansies are great as well for reliable and exciting color throughout the winter. Don't forget, pansies love blood meal. Put about a teaspoonful in each hole before you put the plant in. If we want to take a chance on no freezes during the winter, and that's a fairly safe bet in these days of global warming, we can take a chance on pentas, impatiens and begonias.

Overwintering Pond Plants

Here in South Louisiana we don't have to do much to our aquatic plants in the winter. When they start looking ratty, I cut them back to just above the water line. If you live where it freezes, do the same thing. They will return in the spring, happy and healthy. Water lilies are different, of course. If you live up north and have hardy lilies, remove the leaves and make sure the lily does not freeze solid. I would do that by dropping the lily to the very bottom of the pod. It will come back in May or June.

Finding pond leaks

Sometimes liners do get punctured. Raccoons can leave holes behind after their nocturnal dinners out. Sometimes statues fall in the pond and can puncture the liner. Around here Katrina shoved trees through liners, but they were easy to find. Other times, it's just a good old fashioned mystery.

A friend told me that he finds leaks in swimming pools by slowly pouring in fine sand and watching where it goes.
I would definitely try that if you have decided that you have no waterfall leaks, no tubes or connections are leaking, or your skimmer, if you have one, is not leaking at the liner penetration. It is indeed a great idea if you live where you are not below sea level. Pouring food coloring or a bit of milk in will do the same thing.

Here in New Orleans, we are below sea level, so we rarely lose water from a liner leak. If we have a liner puncture, we have to find where the ground water is seeping in, not where pond water is seeping out! Here's how I do it. I empty the pond. Totally. I have been known to take a hair dryer so I could dry the liner completely. Now look around. If there is water coming in, you have found your leak. If you stilll cannot find it, put the garden hose under the liner and turn the water on. Watch until you see water coming up through the liner. Aha, there's the leak.

Leaks are easily patched with a sticky tape that is much like the stuff you use to patch a tire. You can usually find it in big box stores.

All ponds settle

Probably the biggest problem I ran into while building ponds was water leakage. What pond builders, whether professional or do it yourselfers, fail to realize is that ALL ponds settle. How much depends on where in the world you live. Here in New Orleans I have seen ponds settle as much as 15" over several years because we live in a swamp. When you are building your pond, elevate the sides as much as possible so the inevitable settling does not cause major problems any time soon.
One of the earliest problems with pond settling is water leaking off the back or sides of the waterfall. If your water level drops quickly and for no known reason, turn off your waterfall and fill up your pond. If the water level has not dropped the next morning, you know water is leaking from your waterfall. Usually it is a simple matter to find the miscreant rock and straighten it out. Even if you do have to call someone to move rocks around, you have saved yourself some money by troubleshooting the first part of the problem.

Pond color in the fall and winter

Sunset in Hot Springs, Arkansas.


I am starting to plan my fall garden, while most of you are weeding and mulching, getting ready for a long winter. We rarely have freezes here in New Orleans, so we don't have to plan for that. We just put different plants in the ground.
For you lucky southerners, here's how to put color in your pond in the winter when the water lilies are dormant. Put a painted cinder block in your pond. (I use one painted black so it doesn't show.) Put together a color pot of pansies and snaps or petunias and snaps and put it on top of the cinder block so the bottom of the pot is not or is just a half inch or so in the water. The cinder block should be level with the top of the water or just barely under it. You can leave the pot in the pond or you can change it out to suit you. I put in chrysanthamums now and poinsettias for December. I will do 3 - 5 color pots to make the pond really pop.

Just because the season is drab does not mean the pond has to be.

The Fall Pond

Sunset in Eureka Springs, Arkansas.


The pond in autumn is such a beautiful part of the garden. It shows us, even if we live in the South that the seasons are changing, the plants are reacting to longer nights and shorter days. The new water lily leaves are getting smaller and smaller and there are fewer of them. The fish spend more time at the bottom of the pond just floating there getting ready for winter and their long sleep. Everything tells us that the garden wants rest now and aside from cleaning out pond debris, our maintenance is nearly non-existent.

If your pond is under a tree and leaves are falling, you must remove them before winter sets in completely. They will decompose; the toxins will build up under the ice and kill the fish. Some people put a net over the pond to keep the leaves out. Do not throw visqueen over it because that shuts off oxygen to the fish.

A fish out of water

When it is cold outside, we often need to net just one fish out of the water and no matter how hard we try we can't do it. We often end up cold and wet and covered with pond scum because we tried so hard to reach just a little bit farther. Why on earth would we need to know how to get fish out of the pond? Sometimes fish have some sort of disease and treating the entire pond is almost impossible, but treating a few sick fish is economically feasible.

Pour warm water into one end of the pond. The fish will come toward the warm water and right into the net you have conveniently placed there.
