Calitriche Hamulata is a water star wort, an excellent British submerged native plant. These pond plants are submerged and part terrestrial (grow on land and in water), excellent for oxygenating and maintaining clean and healthy pond water.
Aquatic plant. If purchased from a store or transplanted as an adult plant, you can plant water starwort directly into the silt at the bottom of the pond in as deep as 18 inches of water, though around 6 to 12 inches is best. For younger or less established plants, an aquatic basket can be used until the roots become more robust and are able to hold the plant into the soil.
An ideal soil would be made up of 45% minerals (sand, clay, silt), 5 % organic (plant and animal) material, 25% air and 25% water. The mineral portion would be loam (20 – 30% clay, 30 – 50% silt and 30 – 50% sand).
Cut back in spring to keep in check as it is a vigorous grower. Once the plant(s) die back in the fall, you’ll need to remove any dead matter from the pond to maintain healthy water quality. Seeds can be allowed to drop to the pond bottom or harvested and planted later.
Provide good air circulation, with temperatures between 65 (18 °C) to 75 F (23 °C) and nighttime temperatures between 50 t(10°C) to 60 F (15 °C).
