The Fast-Growing Native Ground Cover That's Perfect For Yards With Damp Soil

Filling in empty spots in your garden can be a chore, but if the spots are in a damp area, the difficulty increases. Whether there's poor drainage or your garden is set in a low-lying area where water accumulates, damp soil can cause root rot and diseases, and overall, is not ideal for many plants' survival. When it comes to filling empty garden space, people often turn to ground cover plants as a beautiful solution. Unfortunately, these wet conditions won't support many ground cover plants. 

There is one, however, that stands out in the crowd and flourishes in wet environments. The sensitive fern (Onoclea sensibilis) actually prefers moist soil, as it is native to swamps and marshes. If you have damp spots where other common ground covers aren't worth putting, it may just be the perfect ground cover for you.

The sensitive fern is a large fern with feathery fronds that grows best in loamy or clay, highly fertile soils. Don't let the name fool you. Ultimately, sensitive ferns are only sensitive to frost and drought. They are capable of growing aggressively, spreading rapidly via spores and rhizomes. This efficient reproduction is actually what gave fern plants an advantage, becoming one of the first plant groups to adapt to grow on land. The sensitive fern is hardy all the way from USDA Hardiness Zones 2 through 10. Deer and rabbits are not usually attracted to the fern when searching for a snack, which is another benefit of growing it as a ground cover.

There are some common mistakes to avoid when growing ferns, such as picking the wrong site. Plant sensitive ferns in a sheltered area, as this is a plant that likes both shade and moisture. Keeping it out of direct sunlight and protecting it from cold winds is important to support growth. Upon the first frost, the vegetative fronds will die off. But never fear, they will be back next year to resume their green expansion.The smaller fertile fronds remain all year. 

It is also vital to understand the best methods for watering ferns to prevent a deadly drought. These plants thrive in wet areas, so you should make sure their soil remains moist — especially in the summer months, when even normally wet spots may dry out. Try to keep the soil damp without waterlogging it. Monitor garden conditions to make sure the soil also remains fertile enough for optimal growth. With the right care, your sensitive fern will flourish.
