A free-form pond can be customized for any landscape, with different rocks, plants, shapes, and waterfalls. But we’ll give you some helpful points on placement, size, and materials.

Before you start, call 811 or your local one-call center to have electric and gas lines marked so you know where to dig to steer clear of them. Then, when you map out the location of your pond, put it where it will be noticed—visible from a window, off a patio, or along a walkway—but away from the play areas of small children or pets. Keep clear of major root systems or mature trees, which can block too much of the sunlight plants and fish need. You’ll also need to be within reach of a grounded exterior outlet so you can plug in a pump, an essential tool for keeping the water aerated; most pumps come with a maximum cord length of 25 feet, and extension cords are not recommended. You may need to bury the power cord a few inches down in PVC pipe to hide it.

Space permitting, you need at least 40 cubic feet for your pond—about 7 feet by 4 feet—to keep the water clean. An initial shallow terrace just inside the perimeter of the pond holds rocks that conceal the liner edge and keep it in place. A second, deeper terrace supports plants that live in the water and help balance the pond’s ecosystem. As you dig, you must slope the sides of the pond so that if the water freezes, the ice will push up instead of against the liner. Even in warmer climates, small ponds can change temperature rapidly, so if you’re adding fish you’ll want a deeper pond that will maintain a more consistent temperature and accommodate the fish—18 to 24 inches for goldfish and at least 3 feet for koi.

To maintain the consistent depth of the water, you need to line the pond. A thin layer of sand and old newspapers or burlap bags softens the jagged edges of rocks and roots. But over that you will need to put a waterproof skin. There are several types of flexible liners meant for small ponds—made from polypropylene and EPDM, among other materials. Look for one that’s weather-resistant, so it will stand up to UV rays and freezing temperatures. It should also be rated “fish-safe” if you plan to stock your pond and come with a warranty of 10 to 20 years so your pond will be watertight for many years to come.

ImageLay out the size and shape of your pond with a rope or garden hose. Using a spade, dig down 3 inches in a 1-foot-wide ring outside the outline to create the stone-border shelf. Next, create a plant terrace by digging a 1-foot-wide shelf 8 inches deep inside the rope outline. Only dig the terrace in areas where you plan to put plants.

Continue digging inside the plant terrace to make the bed of the pond—a minimum of 18 inches deep, with a slight slope.

5 Things to Consider when Adding a Pond:

A garden pond serves as a tranquil haven to any homeowner. It contributes to the overall feeling of serenity and is an ideal relaxing place in your own backyard. Furthermore, having a pond as an addition to your landscape could certainly increase your property’s value.

Although, the construction of a garden pond may appear to be too complex especially for inexperienced homeowners, good planning plus the aid of a professional landscaping company could easily turn the project into a delightful experience.

The following are the prime considerations before adding ponds to your yard:

  • Location
  • Size
  • Water Quality
  • Plants
  • Maintenance

#1 – Location  This is the most vital aspect that determines the success of your pond. Of course, it needs to be placed on a spot that is visually appealing and accessible; however, there are still some other elements that rely heavily on the location. Here are several factors that must be considered:

  • Sunlight. Your pond must receive at least six hours of direct sunlight every day. Most plant species and floras demand direct sunlight. However, too much of it could cause algae to thrive. Therefore, a supplementary exposure of indirect light for about six to eight hours is also necessary.
  • Leaves. Naturally, you would not want your pond to get populated with falling leaves and pine needles. Unattended leaves will decompose within the pond. If you cannot find a location free of overhanging trees and plants, then you might employ catch nets to help solve the problem.
  • Drainage. Your area needs to have excellent drainage systems and is far from flooded buildings and swamps. Excess rain will cause your pond to overflow hence it needs a place to dissipate. Your local landscaping company could help you with drainage solutions.

#2 – Shape and Size  After you determine your ideal pond location, the next thing to do is to layout your pond.   Ponds come in a variety of sizes, anywhere from tens, hundreds, or even thousands of gallons.  But, the most crucial consideration for designing a pond is its chemical stability and temperature. Water stability is directly proportional to the pond size. Therefore, the larger the pond is, the more stable the water temperature and chemistry becomes. This is due to the fact that pH (potential hydrogen) and temperature changes take place more gradually in large volumes of water.   Now you might ask, what is the ideal pond size? Well it actually depends on your preference. Most successful pond owners go for a few hundreds of gallons. However, if you wish to have thriving species of plants and fish, then you could go for a larger pond. You might want to consult your landscaping company for help regarding the appropriate size, shape and depth that would meet your needs.

#3 – Water Quality  In order to sustain life forms in your pond, you also need to consider water quality. It is normal to have water attributes change, but it must occur gradually and not instantly. Abrupt changes in water parameters are the leading cause of poor pond health causing plant and animal deaths. Your water’s chemical and physical attributes must be taken into account and be monitored constantly especially if you have a newly built pond.

  • Potential Hydrogen (pH). The pH levels are used to determine the degree of acidity or alkalinity of your water. It is highly possible to have pH levels of community waters to change; however, it should not occur drastically on your pond. Healthy pH levels for ponds range from 6.5 to 7.5. Your local landscaping company may advise you with the necessary treatments to help maintain water stability.
  • Chlorine. Most water supplies are being treated with chlorine for sanitation. This however, is toxic for aquatic lives. Fortunately, chlorine in the water can be easily removed. There are dechlorinators available that will help keep your water stabilized.
  • Temperature. Temperature is one of the intangible aspects in the environment. Although you could not do much to keep it from changing, you could still maintain necessary water temperatures to sustain aquatic life in our ponds. Such actions include the addition of certain plant types, water change and deployment of pumps. Your landscaping company can recommend actions to help complement temperature change.

#4 – Plants  Plants play a vital role in any pond. It makes garden ponds look attractive and natural, and serves as breeding sites for fish. Water plants also help regulate temperature and help cleanse out nutrients that may pollute the water. The following are the common types of water plants that you may employ in your garden pond.

  • Free-floating plants. These are those water plants that float on the surface of the pond, leaving their roots drooping in the water.
  • Deep-water aquatic plants. These water plants have their leaves floating on the water’s surface with their roots submerged for about 18 inches in depth.
  • Submerged aquatic plants. These water plants are entirely submerged underwater and serve as oxygenators for ponds.
  • Marginal water plants. These plants grow in shallow water and thrive around the perimeter of the water garden.

#5 – Maintenance  The most common problem that is encountered by pond owners is green water. This is caused by an overabundance of free-floating algae consuming plant nutrients. There are certain methods that one could employ to resolve cases of green water. Although there are many natural ways such as the addition of aquatic plants, netting and water change, the most effective solution often employed by pond owners is the application of filtration methods. If you are unsure as to what filtration methods to use, you may seek help from your trusted local landscaping company.   If you consider installing a garden pond in your yard, it might be best to work with a landscaping company to ensure that it is built to cater your needs.
