Emergent Plants: Early spring to summer

Emergent plants are those that root in the bottom of the pond and grow up through the water, with their stems, leaves, and flowers often extending above the water’s surface. These plants are among the first to start growing as the weather warms up in the Southeast.

• Cattails: Cattails are one of the most recognizable pond plants and can start growing as early as late winter to early spring, depending on the temperature. Cattails can quickly establish themselves and spread, so it’s important to monitor their growth and thin them out to prevent them from taking over the pond.
• Pickerelweed: Pickerelweed is another common emergent plant that thrives in the Southeast usually around March or April, when the water temperature begins to rise. Pickerelweed is valued for its attractive purple flowers and ability to provide habitat for wildlife. But, like cattails, it can spread rapidly and may require management to keep it in check.

Submerged Plants: Late spring to early summer

Submerged plants grow entirely underwater and are essential for aerating the water and providing shelter for fish. These plants usually start growing a little later than emergent plants because they rely on warmer water temperatures to kickstart their growth.

• Coontail: Known for its bushy, fan-shaped leaves, coontail typically starts growing in late spring when the water temperature is consistently warm. Coontail is a fast grower and can provide excellent cover for fish – but if left unchecked, it can form dense mats that may require regular thinning.
• American Pondweed: This plant is beneficial for ponds because it provides food and habitat for aquatic life, but it can also spread quickly and may need to be managed to prevent it from becoming too dominant.

Floating Plants: Spring to Fall

Floating plants are those that float on the water’s surface, with their roots hanging down into the water. These plants can start growing in spring and continue to thrive throughout the warmer months.
