A: Those lily pads may provide much-needed shade and protection to your pond’s underwater inhabitants, but if the plants lack those beautiful pink, peach, yellow and white flowers, that could be a sign that something’s amiss.

Here, we’ve outlined some possible causes of your lilies’ missing flowers:

  • Not Enough Nutrients: Curling or yellowing of the leaves or flowers can be signs of nitrogen, iron and magnesium deficiency. Have you fertilized your lilies lately? If not, if may be time to give them a little plant food. Thrive™ Aquatic Plant Fertilizer Tablets slowly release nutrients for up to one month, providing your plants with what they need to flourish.
  • Insufficient Light: Are your lilies getting six to eight hours of partial to full sun a day? Without that sunshine, the plant will appear weak and frail. If they’re under a canopy or in a shadier part of your pond, move them to a sunnier location.
  • Overcrowded Plants: Plants – terrestrial and aquatic – need room to stretch out their roots and grow. If they’re placed in a tiny planter or there are too many packed in one area, this can stunt their development. Take some time to pull out those plant baskets or bags from your pond and divide the lilies into separate pots. Here are step-by-step instructions for dividing water lilies, though we recommend waiting until the spring.
  • Poor pH Levels: Water lilies do best in water that’s in the 6.2 to 7.4 pH range. Check pH levels frequently with a pH Test Kit to ensure the measurements are within that range and correct them accordingly.

Like your roses or other plants in your flower garden, your water lilies will benefit from some regular trimming and dead-heading. Prune or trim any flowers or leaves that have turned yellow or brown. This will encourage new growth – and hopefully some new blooms!

A: Water lilies and lotus … blue flag iris … hyacinth … so many aquatic plants, so little time. A pond full of these colorful beauties – along with the hardworking, submerged oxygenators – adds splendor and life to your waterscape. Not only that, but birds will visit, bugs will buzz through and aquatic critters will stop by, attracted by the blooms and foliage.

Like your terrestrial garden, a water garden needs some planning and forethought; without it, you could end up with an aquatic jungle. Here’s what we recommend for adding plants to your pond.

Choose Wisely
Before you get your feet wet (and your hands dirty!), first consider what types of plants you want in your water feature and how many you’ll need.

Aquatic plants are typically categorized by their function in a pond. They include floating plants, like water hyacinth and water lettuce, that have roots that reach down from the water’s surface; submerged plants, like vallisneria and hornwort, that live on the pond’s bottom and release oxygen into the water; bog plants, like cattails and iris, that ring the perimeter of the pond; and water lilies and lotus, which provide dramatic surface color and underwater shade.

When browsing for plants, select a mixture of floating, submerged, bog and lilies/lotus, with the goal of covering about 60 percent of your water’s surface. A sample plant shopping list for a 50-square-foot pond looks something like this:

  • 6 to 12 floating plants
  • Several submerged plants
  • 2 bog plants
  • 1 water lily

Don’t forget to add aquatic plant media, fertilizer and containers, like pots, plant bags, planting baskets and floating planters , to your list. You’ll need them when you transplant and care for the new greenery. Speaking of which …

Planting How-To
Once you’ve planned out and purchased your plants, it’s time to move them in to your water garden. The different types of aquatic plants need to be handled differently:

  • Floating Plants: Simply place these easy-care plants in the water. They will float freely and take up nutrients through their root systems.
  • Submerged Plants: Grow these underwater plants in plant bags or other planters. Fill your container with planting material, plant several bunches of them together and submerge into the desired section of your pond. Another option: Tie a bunch to a weight and drop it into the pond, using one bunch for every 2 square feet of surface area. Their roots will take up nutrients from the water.
  • Bog Plants: Best grown in containers filled with aquatic plant media, bog plants like their roots wet. Position them around the edges of your pond in 6-inch-deep water, or inside your pond with a floating island planter.
  • Water Lilies and Lotuses: These beauties thrive in pots, like those found in our Water Lily and Water Lotus Planting Kits. To transplant, fill your tub with clay and a clay/soil mix, and add some aquatic planting media on top. Position the tuber inside the soil with growing tip pointed up. Submerge the pot so the plant’s tip is 3 to 6 inches deep. Once the plant starts to grow and its leaves reach the water’s surface, place the pot in a deeper area of your pond.

Feed for Healthy Growth
Your newly planted plants will need nutrients for beautiful blooms, so don’t forget the fertilizer! Aquatic plant fertilizers come in two forms: spikes and tabs.

Fertilizer spikes, like Laguna Plant Grow Fertilizer Spikes, slowly release plant food over a 12-month period. The balanced nutrients encourage foliage growth, root growth and flower production, while their low phosphorous and no-copper formula ensures no adverse effects to fish, plants or water quality. Spikes are easy to use: Push them into the soil (one for every 1 to 2 gallons of planting container space) and forget about them until next year.

Tabs, like CrystalClear® Thrive™, feed aquatic plants throughout their growing season. As with the spikes, the balanced nutrients in tabs encourage greenery and bloom production, but they need to be added to the soil every 2-4 weeks for best results. Use one tablet to two tablets per gallon of potted soil, and push it deep into the media 3 inches from the crown of the plant. Pack the hole with dirt to prevent the fertilizer from being released into the water, and you’re good until next month.

A: A good mix of aquatic plants does more than beautify your water garden. The marginal, floating and submerged plants, such as those found in our Aquatic Plant Packages, also absorb excess nutrients in the water and shade the pond’s surface, which can help prevent algae attacks and protect your finned friends from hungry herons and raccoons.

When planting aquatic plants in and around your pond, you should ideally have 40 to 60 percent of your water garden’s surface covered with floating aquatic plants, like hardy water lilies, water hyacinth and water lettuce. This allows for enough nutrient absorption and shading to prevent algae from gaining a foothold in your pond.

Just like the plants in your vegetable garden, those lilies and bog plants need some nutrients added to their soil to thrive. Here’s what we recommend:

  • Spikes: Fertilizer spikes, like Laguna Plant Grow Fertilizer Spikes, slowly release plant food, which makes them super easy to use. The balanced nutrients in the spikes encourage both foliage and root growth and flower production, while the low phosphorous and no copper formula ensure no adverse effects on water quality or fish and plant life. You simply push the spike into the soil (one for every 1 to 2 gallons of planting container space) and forget about it until next year.
  • Tabs: Tabs, like TetraPond® LilyGro™ Aquatic Plant Food, are formulated for use during your aquatic plants’ growing season. As with the spikes, the nutrients in the fertilizer encourage greenery and bloom production, but the tabs need to be added to the soil monthly for best results. Using one tablet per gallon of potted soil, push it deep into the soil 3 inches from the crown of the plant and pack the hole with dirt to prevent the fertilizer from being released into the water.

During the growing season, plan to fertilize your water lilies and marginal plants once per month. Floating and submerged plants should have plenty of nutrients in the water to feed them. Enjoy your blooms!

Q: Do I need to fertilize my aquatic plants?

Bruce – Taneytown, MD

A: If your aquatic plants look lackluster, aren’t as lush as you’d like or are failing to produce those show-stopping blooms, they might need a little help – and that’s where fertilizers come to the rescue.

Whether we’re talking about plants in your water garden or vegetable garden, the soil they’re living in provides them with nutrients that they take up through their root systems. If you have your plants in pots or if they’ve been in the ground for some time, the soil will need a boost of plant food. Adding fertilizer will encourage quicker growth in new and established plants, and it will deliver enough nutrients for the plants to form those colorful blooms.

So what kind of fertilizer should you use? There are three basic types to choose from:

Spikes: Fertilizer spikes, like Laguna Plant Grow Fertilizer Spikes, slowly release plant food over the course of one year – making them super easy to use. The balanced nutrients in the spikes encourage both foliage and root growth and flower production, while the low phosphorous and no copper formula ensure no adverse effects on water quality or fish and plant life. You simply push the spike into the soil (one for every 1 to 2 gallons of planting container space) and forget about it until next year.

Tabs: Tabs, like TetraPond® LilyGro™ Aquatic Plant Food, are formulated for use during your aquatic plants’ growing season. As with the spikes, the nutrients in the fertilizer encourage greenery and bloom production, but the tabs need to be added to the soil monthly for best results. Using one tablet per gallon of potted soil, push it deep into the soil 3 inches from the crown of the plant and pack the hole with dirt to prevent the fertilizer from being released into the water.

Liquids: Liquid fertilizers, like Microbe-Lift® Bloom & Grow Aquatic™ Plant Supplement, add micro- and macronutrients to plants through the water rather than soil. These supplements, which need to be added to the pond water once or twice a week during the plants’ growing season, help produce brighter, faster blooms and healthier, stronger roots. The liquid fertilizers are safe to use around fish, but unsafe if the water is intended for human consumption.

No matter which form you choose, make sure it has no or low levels of phosphates, which fuel algae growth. You want your plants to grow – not the green water, right?

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.

Let’s face it: floating and surface plants, like lilies and hyacinths, are the rock stars of any water garden. They’re the show-offs, the preeners, the colorful ones that visitors “ooh” and “aah” over; the divas that pond owners proudly feature on center stage.

But, may we ask, where would the rock star be without his support crew – the techies, the roadies, the groupies? Still playing air guitar in front of his mirror, that’s where. Lilies, hyacinths and the like just happen to be the most visible and attractive feature of a supportive ecosystem that should include their plainer relatives – the Submerged plants, like Vallisneria, Red Ludwigia, Hornwort and Parrot’s Feather. These worker plants compete with algae for the nitrogen produced by decaying plants and fish waste,produce oxygen to help keep the pond properly aerated,andprovide shade and shelter for koi and other fish. Submerged plants may not be flashy, but they’re a critical component in maintaining water quality and general pond health.

The easiest way to add one of these workers to your water garden is to plant its stems in a Laguna Submersible Pond Planting Basket along with an ample supply of Microbe-Lift® Aquatic Planting Media, and place it on the bottom of the pond. The baskets come in various sizes with mesh sides and bottoms – this allows the plant to seek nourishment outside the basket, without the risk of growing out of control.

Any performer will tell you that a well-fed support crew is a happy support crew. So to make sure your Submerged plants are getting the nutrition they need, we highly recommend the Laguna Temperature Activated Aquatic Fertilizer Spikes, a verbal mouthful that also delivers the goods. Simply push a spike into to the soil near the plant until the cap is just above the surface and you’re all set for a year.

So, by all means, add Submerged plants to your water garden and let your lilies rock on!
