How Do You Divide Water Lilies? | Decorative Ponds & Water Gardens Q & A

How Do You Divide Water Lilies?

Cindy – Galesburg, IL

Dividing lilies may seem somewhat complicated, but our step-by-step process will explain exactly what you need to do. Try to plan it so you divide them during your spring cleanout, which would give easy access to tubers. Dividing is necessary every two to three years, and it is helpful if you notice the lily grew mostly pads and few lilies over the past season.

Step 1: Remove lilies from pond or container and rinse off. Plant baskets are ideal containers until they are ready to be moved to the pond.

Step 2: Trim away root growth and old foliage.

Step 3: Cut the tuber down to size. You can safely cut the tuber down between two to three inches on the growing part with a sharp knife. This can be increased to five to six inches on longer plants. Remember to also cut off new buds and older leaves, so that the new root system has a chance to grow.

Step 4: Plant each tuber separately or discard if you wish to reduce the lilies’ quantity in your pond. Use plant fertilizer and planting media for best results and a continuing healthy pond.

Step 5: Replant them shallow in the pond until new growth begins.

Step 6: Upon new growth lilies can be moved deeper into the pond.

What Considerations Should I Make When Ordering Plants For My Water Garden? | Decorative Ponds & Water Gardens Q & A

What Considerations Should I Make When Ordering Plants For My Pond?What Considerations Should I Make When Ordering Plants For My Pond?

Monna – Kettering, OH

3 Considerations to Make When Ordering Plants for your Water Garden:

1.) Hardiness Zone: Another thing to consider when order plants are the hardiness zones and shipping times. Plants are assigned a hardiness zone depending on the type of climate they can tolerate. Choosing plants that will do well in your zone will allow for greater success. Due to the cold weather, we will hold your plant order for you and ship it once your location is past the last frost warning for the season. This ensures the plants ship at a time that is more suitable for travel and save you the hassle of trying to store them until spring.

2.) Variety: There are numerous varieties of plants to consider when ordering. Floating plants such as water hyacinth and water lettuce are great to extracting algae-causing nutrients from the water. Submerged plants such as hornwort are oxygenators that will create oxygen throughout the water column. Also, submerged plants add hiding plants for koi and other fish. Bog/marginal plants such as dwarf cattail or arrowhead add a nice touch of nature to any water garden. Water Lilies of course add beauty and color and like floating plants add shade and protection for koi and goldfish.

3.) Coverage: We recommend adding enough plants to cover 60% of the surface of the pond. This balances sunlight and shade and ensures a balanced ecosystem.

If you are unsure of which plants to order or how many, The Pond Guy keeps it easy with Aquatic Plant Packages.

What Can I Do To Maintain My Pond This Season? | Decorative Ponds & Water Gardens Q & A

Can sidewalk salt be used to melt the ice off my pond?

This will be our first full season with our pond. What should we do for proper maintenance?

Joe – Aurora, CO

The first season with your new pond can be an exciting and relatively hassle free endeavor, as long as you take the right precautions to maintain it properly. Lucky for you, you’ve come to the right place to learn exactly what you’ll need in order to successfully maintain your pond for the season.

Remember, a balanced ecosystem is key. Listed below are the main elements used to maintain a balanced pond.

Filtration – Whether you have a waterfall, pressurized or gravity type filter, make sure the included Filter Media is clean and in good condition. Mechanical filtration like skimmer filters should be cleaned regularly to prevent clogging. Biological filter media, like the pads in your waterfall or bio-media in your pressurized filter, should be cleaned sparingly to promote an accumulation of water-filtering beneficial bacteria.

Fish – The highlight of many ponds, fish add color and life to your decorative pond. They also, however, add waste and nutrients that can quickly accumulate and unbalance your pond. 1-inch of fish for every square foot of surface area is a rough guideline for maximum fish load. Keep in mind that your fish are continually growing. That means your 3 inch fish that were added last year are now 4-6 inch fish which more than doubles the waste that needs to be filtered. The more fish you have and the frequency at which you feed them plays a large role in how much filtration you will need to remove this additional waste.

PlantsAquatic Plants are an enormous natural boon to your water garden or fish pond. Not only do they provide habitat for your fish, maintaining 40-60% plant coverage shades your pond and prevents dramatic increases in water temperature on sunny days. Plants also provide additional natural filtration as they extract nutrients from the water added by organic debris and fish waste.

Aeration – Proper aeration is another key factor for pond maintenance. An aeration kit like the Pond Logic® PondAir™ or KoiAir™ will provide extra circulation to keep debris from accumulating at the bottom of the pond while increasing oxygen levels for your fish and water-filtering aerobic bacteria.

Natural Pond Treatments – Natural products like those contained in the Pond Logic® DefensePAC® will greatly increase water quality by boosting aerobic bacteria counts, binding up phosphates from organic material and eliminating organic debris.

Including each of these key pond elements in your water garden or fish pond greatly reduces stress and guesswork associated with a troublesome unbalanced pond. Simply put, a stable ecosystem means less work on your part. If a problem does arise, you can then pinpoint and adjust whichever element above that is throwing your pond out of balance.

Should I use a heater or aerator in my water garden? | Decorative Ponds & Water Gardens Q&A

When should I remove the fountain from my pond?

Should I use a heater or aerator in my water garden?
Lindsay – Pittsfield, ME

So you already know that it is important to keep a hole open in the ice that forms over your water garden during the winter months. This provides an outlet for harmful gases and an inlet for new oxygen-rich air. The question now is which device do you choose to get the job done. The good news is if you have already made your purchase for the season either one will perform excellently. Both a heater and aerator will maintain a hole in the ice but unlike a pond heater, this is only one of many tasks an aeration system performs for your water garden.

When we talk about pond heaters we are referencing units like the K&H™ Thermo-Pond 3.0 Pond De-Icer which does not heat the water in the pond but instead keeps a ring of water open allowing gas to escape through the vent in the top of the unit. Since most ponds deeper than 18” do not freeze solid this is all that is needed to allow oxygen exchange while the fish are dormant. When running a pond heater periodically check in on the pond to make sure ice does not form over the vent hole. To reduce electrical expense most pond heaters are thermostatically controlled to run only during a given temperature range, but they are measuring water temperature instead of air temperature. This means it is unlikely that the water temperature will raise enough to ever shut off the heater. To save some extra money on energy bills use a Thermo Cube® in tandem with your pond heater as it will determine when your pond heater should run based on the ambient air temperature.

Aeration keeps a hole in the ice during the winter by producing bubbles and water motion to slow the ice from forming. This allows for the same gas exchange created by a pond heater, however your Aeration System will circulate the entire pond volume and infuse it with dissolved oxygen making it more efficient at oxygen/gas transfer. People will sometimes run pumps beneath the ice trying to create this same effect but it is the tiny air bubbles that boost dissolved oxygen levels and create the friction that prevents ice from forming. Your pond benefits from aeration year round making an aeration system a helpful and highly functional tool regardless of the season. The installation process is simple and straightforward and aeration systems are available in various sizes and shapes allowing you to select a system that best fits your pond. When selecting a system make sure you purchase a unit that is rated for your ponds volume in order to provide enough outlet for proper gas exchange.

The performance of both pond heaters and aeration systems vary depending on how cold it gets in your area. Even when vented properly, layers of ice appear may over when temperatures dip well below freezing. If this only occurs temporarily, and is short in duration while the coldest temperatures and wind are present, there should not be any cause for concern, as a calm or sunny day will give the pond the help it needs to re-open the hole in the ice. If it is necessary to manually reopen the air vent do not try to break through it by hitting it with hammers or heavy objects as this creates vibrations that can harm your fish. If necessary pour a bucket of warm water over the vent hole to melt it back open.

Whichever unit you choose to use will perform to keep your fish safe for the winter months and ensure that they will be healthy, happy and ready to go in the spring.

Do I need to remove the UV in my pond for the winter? | Decorative Ponds & Water Gardens Q&A

Andrew – Memphis, TN

Like a lot of people, UV components don’t tolerate cold very well. Unlike people (most people, anyhow), those components tend to crack when frozen. So, in the interest of avoiding unnecessary expense when you bring your pond back online in the spring, removing your UV for the winter months is a wise course of action.

In ponds where the UV is a component of the filter system, the same rule applies: it’s worthwhile to take the entire filter out for the winter. Fortunately, the task is pretty straightforward. When the time comes to shut the pond down for the year, the first step is to drain the water from the UV/filter and give them a thorough cleaning. Next, be sure to cap off the tubing ends with a plastic bag or a snug-fitting cap to keep debris from entering the system. Finally, place your filter components in dry storage to keep them in good shape for next season.

But wait! What about your fish? Even though you’re done with your pond for the season, they’re not going anywhere – and they’ll still need an adequate supply of oxygen to survive the winter. And nothing provides oxygen more reliably than our Airmax® PondAir™ Aeration System and our Airmax® KoiAir™ Aeration System. With the addition of one of these systems, you’ll ensure winter water circulation – and keep your pond water well oxygenated for the fish that make your water feature a three-season sight to behold.

When should I switch my fish food? | Decorative Pond & Water Garden Q&A

When should I switch my fish food?

When should I switch my fish food?

Jordyn – Milwaulkee, WI

If you’re eating fish food, you should probably consider switching it right away. I recommend pizza. Unless, of course, you’re a fish – which, for the purposes of this post, we’ll assume you are.

Fish, as you probably know, are extremely susceptible to seasonal cycles, and the environmental changes they bring. When gauging the best time to transition from one type of food to another, it’s vital to monitor water temperature – which, when you use our Pond Logic® Floating Pond Thermometer, is a snap. The second, more subtle indicator is fish behavior. When water temperatures drop below 50 degrees Fahrenheit, fish movement become slower and more sluggish, or they’re eating significantly less, it’s time to switch to a wheat germ-based food like Pond Logic® Spring & Fall Fish Food.

When fish ease toward their dormant months, wheat germ-based food provides easily-digestible nutrition, and ensures that your fish won’t go dormant with undigested food in their bellies. Because undigested food decomposes over time, it poses a serious health risk to fish, and can release toxins into their systems that can result in sickness – and even fish loss. When using our Spring & Fall Fish Food, you can continue to feed your fish safely, without exposing them to unnecessary risk of illness.

When water temperatures drop into the 40s or fish stop eating altogether, it’s time to stop feeding, allowing fish to settle in safely for their long winter’s nap.

I empty my skimmer every day. Is there a better way to keep leaves out of my pond? | Decorative Pond & Water Garden Q&A

Joseph – San Francisco, CA

Leaves are notoriously difficult to train. Try as you might, they simply fall wherever they please. And when their drop zone of choice is your pond, the task of cleaning them out quickly loses its novelty. Fortunately, there are lots of ways to keep even the most determined leaves out – and cleaning your skimmer on a regular basis is just the beginning.

For those who experience limited leaf drop in their pond, a skimmer may do the lion’s share of the work by gathering up the majority of floating leaves and debris. For any surplus, and for leaves and debris that sink to the bottom of the pond, hand nets and vacuums may be sufficient to keep your water clean and clear.

But not everyone enjoys the satisfying sense of accomplishment that comes with manual leaf removal. If you’re one of those who don’t, we strongly recommend the use of pond netting to stop leaves before they reach the water. At The Pond Guy®, you’ll find plenty of options. For economical, single-season purposes, try our Dewitt Economy Pond Netting. For a more durable option that stops leaves and debris, keeps predators at bay and allows abundant light penetration, consider our Clear Fine Mesh Pond Netting. For durable protection that will provide years of use, the nylon mesh construction of our Premium Pond Netting is an exceptional value.

For the ultimate in pond protection, though, our Nycon Big Top Pond Cover is a natural choice. Designed to prevent penetration by even the smallest debris – while keeping predators out – this durable cover forms a tent over your pond, and will provide years of seasonal service.

However you choose to preserve your pond’s pristine appearance, timing is of the essence. As soon as leaves start to fall, it’s time to take action. And whether you’re skimming, cleaning or covering, we have everything you need to make the job a breeze.
