Soil washes away from slopes and puddles during heavy rain. Standing water can ruin the health of plants and lawns because it makes the roots weaker.
You need suitable plants that prevent soil erosion for the Connecticut weather. Some native plants are appropriate for wet soil and steep slopes in Connecticut. Let’s find out!
Plants to Reduce Erosion and Improve Drainage!
Roots connect the soil particles and prevent erosion. The foliage and stem can slow the speed of water as it flows across your lawn. Roots also form small holes in the soil, so rainwater can filter into the ground in these areas.
Plants can assist with minor runoff problems; however, they will not correct serious drainage problems. If water pools near your foundation or your yard floods often, it is time to hire a lawn care professional.
Inspect Your Yard
- Walk in your yard after every spell of heavy rain. The presence of puddles and bare soil is a red flag.
- Observe the direction of water flow.
- Next, check sunlight, as some plants prefer shade.
- Always test your soil before plant purchases. Clay soil is slower than sandy soil. Plant for the moisture and sunlight conditions in your yard.

Switchgrass and little bluestem have a fair tolerance to road salt. They are both good roadside plants for sunny locations. Too much salt injures plant roots. Avoid having significant amounts of road salt near plants.
Sedges native to their region make excellent ground cover for areas around walkways with wet soil. People also plant them for their roots, which cover areas of bare soil that receive runoff from impervious surfaces.
Plants for Wet and Dry Conditions!
Seasonal moisture and dry periods after establishment are not harmful to switchgrass. Allow adequate space for plant development. Try not to have big shrubs in close proximity to narrow paths that block access.
