Q: Do you have any tips for adding plants to my pond?

Patricia – Charlestown, WV

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.

I just bought a plant package. What should I do now? | Decorative Ponds & Water Gardens Q & A

Rick – Winchester, NH

A: Congratulations! For water garden enthusiasts like us, opening an aquatic plant package is like celebrating Christmas in spring. A box of colorful flower tubers, oxygenating plants and algae-eating snails arrives at your doorstep, and you get to look forward to a season of fun in your backyard playground.

Depending on the package size (small, medium or large) you received, you’ll get:

  • Water lilies
  • Floating plants, like water hyacinth, water lettuce and parrot’s feather
  • Bog plants, like blue flag iris and dwarf cattail
  • Pond snails

These pond plants work together to shade the pond, aerate and filtrate the water, provide habitat for wildlife and insects (and your snails), and beatify your landscape.

Ready to get growing? Here’s how to care for – and play with – your Christmas-in-spring present.

Pond Snails

After traveling all those agitating miles to your doorstep, the Black Japanese Trapdoor Pond Snails may appear lifeless or even dead, but don’t worry: They’re most likely hiding inside their shells. Wake them up and welcome them to your garden by filling the bag halfway with pond water, and then floating or holding it for a few minutes while the gastropods acclimate to the new environment. Then place the open bag in a shallow area and let them work their way out and into the deeper section of your pond.

Plant Care

Before your plant package arrives, purchase some planting containers (like baskets, bags or pots) and aquatic planting media. Use soil designed for water gardens; avoid using bagged potting mix and other lightweight soils from your local garden center, as they will float and cloud the water in your pond.

  • Water lilies: With your pots and plant media ready, take out your water lily tubers and place one inside a pot with the growing tip facing outward. Fill in around the tuber with the aquatic planting media, making sure the roots are well spread and the crown is sitting just below the soil surface. Place the planted pot in a shallow area of your pond to encourage faster growth. Once leaves have reached the surface, you can move the water lily to a deeper part of your pond.
  • Floating Plants: These plants are easy to propagate. Simply place in the water! They will float freely and take up nutrients from the water through their root systems.
  • Bog Plants: Like the water lilies, these around-the-edge plants require a pot and planting material. Position the tubers in the media so that the cut end of the tuber is against the side of the pot, not in the middle. Why? Because the roots need as much room as possible to spread through the soil and across the container. Once it’s planted, submerge the container on a shelf that’s up to 6 inches below the water surface.

Keep Them Growing

Like the plants growing in your vegetable garden, your aquatic plants will require fertilizer to help them grow healthy and strong. Spikes or tabs, like CrystalClear® Thrive™ tablets, can be pushed into the soil at planting time. They’ll slowly release into the media, feeding your lilies and irises the nutrients they need to thrive. From April through August, continue to feed your plants, following all manufacturers’ recommendations for fertilizer application rates.

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!

Water Garden & Feature Q & A

Q: I would like to fertilize my aquatic plants but I heard fertilizing can cause algae blooms. Is this true? – Alan of New Jersey

A:Fertilizing your aquatic plants are a great way to ensure healthy and blooming plants all season. Most water garden owners are afraid to fertilize their aquatic plants because they feel that it will cause algae blooms. This isn’t the case when using low-phosphorus fertilizers.

Initial Planting of Aquatic Plants
When planting aquatic plants I suggest using Aquatic Planting Media instead of soil because it is a great way to get your plants off to a good start. Aquatic Planting Media is pre-colonized with beneficial bacteria to help initial growth. Planting media can be used in lily pockets or when plants are
placed in a pot.

Fertilizing Your Aquatic Plants:
Bloom & Grow™ is a nitrate and phosphate free supplement that is formulated for aquatic plants of all types to promote larger, brighter and faster blooms as well as healthier and stronger roots. Aquatic Plant Fertilizer Spikes are also a great way to fertilize your plants. Just one application will fertilize plants for the entire season.

These above methods will allow you to enjoy those gorgeous blooming aquatic plants without having to worry about excessive algae blooms.
