Water Plants

• Line your open weave black plastic baskets with burlap or black, porous landscape fabric so soil can’t escape and cloud the water.
• Use an aquatic soil for water plants and be sure to cover it with washed gravel, pebbles, or small rocks. The added weight keeps the planter from popping to the surface.
• Place each planted basket in the pond at the required growing depth of each type of plant. If you need to raise a container higher, be sure to place the riser on an extra piece of PVC to protect the PVC liner beneath from tears.
• To eliminate the salt in a concrete block, immerse it completely in a bucket of water for 24 hours. It will take several weeks for your water plants to start growing. Your water may turn green during that time. There will come a time when the water suddenly clears and, if it doesn’t, keep adding more plants.
• Remember Melantho Snails live solely on algae. They’re just as important to your miniature eco-system as the fish, frogs, and dragonflies.

• Check all filters in your pond once a week. Less output from fountains, waterfalls, or pumps may indicate that a hose is clogged or the filter is dirty and may require cleaning or replacing.
• Water contains elements such as salts and nitrates which remain because evaporation is 100% pure. The build-up of these elements is one of the major causes of algae. These plants will absorb both; you just have to establish the right ratio of plants to the volume of water.
• When filling your pond for the first time, let the water sit for a week. It may turn green but do not empty it.
• After a week it will be safe to start adding water plants.

Water Lilies

Water Lilies come in two forms; hardy and tropical. Hardy plants can be cut back and left in the water garden over the winter. Tropical plants are treated as annuals or lifted and wintered inside.

• The major visual difference between the two is that hardy Water Lily blooms sit on the surface of the water with the foliage while tropical blossoms rise on long stems well above the leaves. Both are easily grown requiring a minimum of 6 hours sunlight daily, rich soil, and quiet water. They are placed 45 cm – 60 cm (18” – 24”) deep with 20 cm – 30 cm (8” – 12”) of water over the crown of a hardy Water Lily and 15 cm – 20 cm (6” – 8”) over the crown of a tropical.
• Hardy Water Lilies bloom yellow, red, apricot, white, and pink.
• Tropicals are white, pink, red, yellow, purple-violet, and blue.

• Lotus leaves and flowers stand 45 cm – 125 cm (18” – 48”) above the water depending on the variety. Exotic fragrant blossoms last 3-4 days allowing the unusual seedpod to develop.
• Lotus requires many weeks of sunny, warm weather and rich soil to bloom well. Hardy to Zone 5, it sometimes won’t flower the first year.
• To overwinter, ensure your lotus is at least 3.5 feet deep in your water garden to protect the tuber from freezing.

• These water plants are classified as “floating” oxygenators. They liberate oxygen that helps to clean the water, and they absorb excess nutrients that cause algae.
• Floater plants float on the surface with their roots dangling in the water, moving wherever a breeze takes them. They shade the water and provide protection for fish.
• They include Water Lettuce with its soft, velvety, blue-green leaves arranged in the form of a rosette, Water Hyacinth with its’ shiny, leathery leaves and blue flowers, and Duckweed with tiny leaves and spreading habit. Duckweed is also food to goldfish. For Water Lettuce and Water Hyacinth Use one plant per square meter (yard) of water

• Oxygenating plants are planted in pots that are placed right at the bottom of the pool. These plants also keep water clear and they control algae naturally.
• They provide spawning space for fish and provide shelter for baby fish.
• There are many submerged oxygenating plants to choose from but there should be a maximum of three plants per square meter (yard).

• Planted in shallow water at the edge of a water garden, marginals soften the edge of your feature and give it a natural appearance.
• Hardy shallow water plants include Arrowhead with its distinctive leaf and spikes of delicate white, three-petalled flowers. Pickerel Rush produces tight clusters of blue flowers on tall spikes from midsummer to fall. Variegated Sweet Flag is particularly distinctive with slender green and cream leaf blades.
• There are also tropical marginals some of which can be kept indoors as houseplants. Others should be treated as annuals and replaced each year. Read plant tags carefully to confirm their care tips.
