Floating Pondweed
Floating Pondweed (Potamogeton spp.) is a hardy aquatic perennial plant hardy in USDA hardiness zones 4-11. These plants grow in or near standing or running water and like calm water conditions with low swift currents. As their name indicates, the roots of this aquatic plant penetrate the mud or sandy bottom of the water allowing the leaves to float on the surface. They can also survive in slightly salty waters. The leaves are long and can be round or have multi lobes that look like fingers. Their color range is not as diverse as stemmed pondweeds since their only colors are generally either dark or light green. Depending on the species, the flowers sport either dark green or yellow spikes. These plants drops their flowers, seeds and leaves in autumn, in order to survive the winter season in a dormant state and start anew in the early spring.
Floating Pondweed requires constant and consistent water supply. They are tough plants that can provide a variety of plants with cleaning water. These plants tend to be more prone to dehydration than it is to waterlogging. To help them endure the heat, they prefer a steady supply of water. It is best not to over water them. In a cold winter season, when rains are not frequent, make sure to give them water once in a while.
Floating Pondweed can grow in both sunny and partially shaded areas. It prefers green and white spectrum of light to develop the nicer shade of foliage and flower spike for the species. Most of the times these plants show faster growth rate in areas of full to partial sunlight. On the contrary, they can also manage in partially shaded areas, keeping the amount of light to its limits.
Floating Pondweed are able to live in temperatures ranging from -23°Celcius to +45°Celcius. They can tolerate some degree of frost in winter, but make sure to give them enough shade if the temperature rises above 32°F (0°Celcius). During hot summer months, temperatures of 86°F (30°Celcius) may cause winter damage, so you should make sure they are protected appropriately.
Floating Pondweed prefers slightly humid air around them since they can tolerate dry and humid environment due their root system. If the surrounding temperature exceeds 45°Celcius during hot summer days, you should mist the plants once in a while or provide some shade with natural or artificial covers.
Floating Pondweed is an aquatic plant and prefers to live in permanently wet or standing water. It is best to provide them nutrient-rich soil with proper drainage. The ideal soil should be able to hold water but not be waterlogged. A good mix for this would be one part of soil, one part of clay and one part of mulch such as peat moss and vermiculite.
Floating Pondweed does not require much fertilization. However, if you wish to fertilize them, you can use a water-soluble fertilizer in regular intervals. It is important to note that too much of fertilizer can be damaging to the plant, so make sure to stick to the instructions on the package and use the right amount of fertilizer.
Floating Pondweed is generally resistant to most pests. However, they can be affected by snails, slugs, aphid, and other pests. To prevent these pests, you can spread diatomaceous earth around the plants to keep them away. If there is an infestation of pests, you can use a combination of neem oil and other anti-pest organic products. Neem oil should be sprayed directly onto the plant parts that are affected and it should be done sparingly with intervals of 7 to 10 days. Keep the affected areas sprayed as long as the pests exist in the garden.
Floating Pondweed generally does not require repotting. They have very delicate roots so repotting should be done carefully as it can be very damaging to this aquatic plant. Only repot when roots become congested or when pot size is too small to provide enough space for the roots to spread out.
Floating Pondweed does not need regular pruning and should only be pruned if necessary. Prune overgrown plants when they become too thick and cut back the leaves to thin out the growth. You can also trim off any brown or dead leaves as they don't look attractive. However, make sure not to prune more than 20% of the plant in a season as it can hinder its overall health.
Floating Pondweed does not need mulching, as it is an aquatic plant that prefers to live in standing or running water. However, if you choose to use mulch, you should opt for organic mulches such as peat moss or sphagnum moss.
Floating Pondweed can be propagated using stem cuttings. You can also propagate this plant by dividing the rhizomes. Cut the rhizome into 4-5 sections and each section can be planted into its own pot. This method is the fastest way to grow more of this species. You can also reproduce it through seeds, but it takes a longer time to see the results.
There is no need to provide support as Floating Pondweed is an aquatic plant that is capable of floating on its own in standing or running water.
Floating Pondweed does not require a rest period and can grow year round. However, they may experience winter dormancy in colder temperatures and will need to be kept in a warm location at these times.
Floating Pondweed is not toxic to pets. However, make sure to keep them away from the plant as they may cause damage to it.
