Rooted water herb with slender, branching stems and tiny leaves edged in sawlike teeth
Beyond the saw-like leaves and the tolerance for alkaline water and poor sunlight, the Spiny Naiad shares the physical attributes, habits and lifestyle of the other Naiads. It is a rooted plant that is heavily branched and grows entirely under water. It is greenish with a tint of purple or brown in colder seasons. Its flowers and seeds are extra-tiny and hard to spot because they grow close to the leaves. The Spiny Naiad is native to the US and can be found across the country. It is, in fact, found across the world. It is, as noted earlier, not choosy. It will grow in fresh water as well as brackish and alkaline water. It is a seasonal plant that has the ability to reproduce through fragmentation but rely more on mass seed production. The mass seed production is one of the remarkable features of Naiads. A hectare of the weeds can produce upwards of a million seeds in one season. The seeds are then dispersed through a clever technique. The plant's twigs break away, with leaves intact and seeds safely attached, allowing water currents and wind to carry them away. Along the way, the seeds detach from their ride and sink to the bottom, ready to start new weeds when the season turns.
he normal approach is to cut and rake the Spiny Naiad out of the water. The technique is fairly successful if done before the seeds mature and the twigs detach from the plant on their dispersal missions. One of our weed control products, the Deskuzzer, is particularly suited for the task because it has a long reach. It is a 5 foot wide floating seine with sturdy abrasion, ultra tough screen, and a 24 foot pull line that makes it easy to gather the weed. A more thorough technique is to use another of our weed control tools, the Lake Bottom Blanket. This is a 10 feet wide sheet of specially treated polythene that is anchored in the water by weights so as to block out sunlight. It is made of lighter-than-water material, enabling it to remain suspended in the water without touching the water bed. That leaves plenty of space for fish and other aquatic animals to go about their business as usual. The Blanket has already been proved effective in over 400 lakes in 29 states, with a 100% kill rate of weeds in less than four weeks. The Blanket is dark on one side and white on the other, a combination that totally blocks sunlight. Even the Spiny Naiad which can survive in limited sunlight cannot handle the sunless environment. The Lake Bottom Blanket is approved for use by the DNRs and DEPs of California, Nevada, New York, Connecticut, Massachusetts, Washington. Is there something about weeds that you would like to know?
