...Waterplants...

 

From early May through the summer we provide high quality Waterplants for your ponds and water gardens. Waterplants add an attractive naturalizing effect to your pond, as well as reducing the amount of algae. Go for a varied collection of water plants for each pond. Water Lilies and Water Hyacinths boast beautiful flowers and also help to shade the water, which reduces algae growth. Marginal plants placed around the edge of the pond help make the pond look natural. Choose oxygenating plants such as Hornwort, which is submerged in the water, to reduce algae growth even further.

The best selection for Waterplants is in the month of May and June; however you can purchase many plants well into late summer and early fall.

-open/close- -open/close-Success with Waterplants – Care & Tips


Light:

Waterplants require a full sun to part shade location. Provide most varieties of Waterplants with a minimum of 4 hours of direct sun every day.


Fertilizer:

Feed potted Waterplants with waterplant fertilizer monthly from April to September. This specialized fertilizer is available as a tablet; you can easily insert the recommended quantity of tablets into the soil of the plant so it can be absorbed by the roots. Floating water plants like the Water Hyacinth do not require any fertilizer, as they take the nutrients they require directly from the water.

Repotting:

When repotting your Waterplants you should use very heavy, clay-like garden soil; a water garden soil mix is available and is an excellent potting medium for all of you pond plants. To repot your plants, carefully remove from its existing pot, place it in an appropriate pot and add water garden soil to fill the extra space, maintaining the soil level. Gently water the new soil to help prevent it from clouding the pond water, then lower the plant back into the pond. You can place a thin layer of small stones on the surface of the soil.

Water Lilies should be planted into fairly large containers to allow them to grow and produce more flowers. A small-sized Lily should be good in a 10” to 12” pot; a larger Lily should be planted into a pot approximately 15” or larger in diameter. Marginal plants do well in an 8” to 10” pot.

Plastic Pots are available in many sizes and are the ideal choice for repotting your Waterplants. Mesh pots are also available in some sizes.


Algae:

Algae growth occurs in all Water Ponds, especially early in the season and in new ponds; its growth is accelerated by sunlight, warm water and dissolved nutrients (from fish, soil, decaying matter, etc.). Although most find it unattractive, algae is common and completely harmless.

To Discourage Algae Growth:

  • Avoid changing the water, as this adds more nutrients for the algae.

  • Have a mixture of plants for the pond and provide 60% of the water surface with shade. Hornwort and Water Hyacinths help to remove nutrients from the water. Water Lilies and Water Hyacinths cover the surface, providing shade for the water.

  • Add a filter to collect debris.

  • BE PATIENT! Allow the pond time to achieve a good balance between plants, nutrients, light and temperature.


Overwintering:

Water Lilies can be overwintered in the bottom of your pond, provided you can move it to an area that is at least 2.5-3' deep. Return your Water Lily to shallow water in the spring for better growth and flowering.

If your pond is not deep enough to overwinter a Water Lily, remove it from the pond late in the year, clean off the leaves and place it in water in a cool spot such as a fruit cellar (around 5 C) for the winter. Keep it moist, cool and dark. Return it to the pond as soon as temperatures stay warm enough in the spring.

Hardy Marginal plants can remain in the pond during the winter months.

Some Tropical Waterplants can be brought indoors for the winter and kept growing in a shallow pan of water that is placed in a sunny window. Water Hyacinths should be treated as an annual and composted.

Water Plant Care Tips:

  • Place Waterplants in water immediately upon returning home. Waterplants can remain out of water for 1 hour; during this time keep plant out of direct sunlight.

  • Raise Water Lilies up to about 12” below the water's surface for the growing season to encourage growth and flowers.

  • Keep Tropical Waterplants indoors until there is no risk of frost; air and water temperature should stay above 10ºC, usually around the end of May.

  • Reduce algae growth by providing shade for 60% of the water's surface and placing Hornwort in the pond.

Choosing a Water Lily
Water Lilies can be used for nearly every size of water garden or pond, and can even survive in “tub gardens” if given the right conditions.
Here is a list of our recommendations, according to spread:

Small Ponds: Spread: 15 – 75 cm (6” – 30”), Water Depth: 10 – 20 cm (4” – 8”)
Medium Ponds: Spread: 75 – 120 cm (30” – 48”), Water Depth: 25 – 50 cm (10” – 20”) Large Ponds: Spread: 150 – 215 cm (5’ – 7’), Water Depth: 25 – 60 cm (10” – 24”)

Repotting Water Lilies
Use very heavy, clay-like garden soil; Belgian sells a water garden soil mix that is an excellent potting medium for all of your pond plants. Carefully remove plant from its existing pot, place it in an appropriate pot and add water garden soil to fill the extra space, maintaining the soil level. Gently water the new soil to help prevent it from clouding the pond water, and lower the plant back into the pond. A thin layer of small stones can be laid on the surface of the soil.

Water Lilies should be planted into fairly large containers to allow them to grow and produce more flowers. A small-sized Lily should be good in a 10” to 12” pot; a larger Lily should be planted into a pot approximately 15” or larger in diameter.
