Selecting the right plants for wet land in Ohio

I recently wrote about gardening for climate change and adapting to changing precipitation patterns and periods of drought from a general standpoint. However, thinking about the way the weather has changed more locally, in Northeast Ohio, it definitely seems to be wetter more consistently and for longer periods of time. Logically, those of us with wet yards need to consider planting trees, shrubs and groundcovers that are more tolerant to wet conditions.

Not all plants grow well in wet areas

Many plants struggle to grow when soil is constantly wet because their roots require oxygen and saturated soil has no room for air. Trees and shrubs may be able to survive but often experience weak root growth and grow poorly as a result. These plants will also be more susceptible to soil-borne diseases and other issues.

Defining a wet area

A wet area constitutes more than an area of land that is wet all of the time year-round. Sloped sites are not always well-drained and can be considered wet when the soil is composed of a high clay content or it has a high water table and holds too much water. Other sites may appear well-drained for most of the year, but could still be too wet to support many trees or shrubs. These sites typically drain slowly and stay wet for extended periods of time when rain is abundant in the spring and fall.

Amending the soil

Soil amendments only relieve soil moisture problems if the entire root zone of a mature plant can be altered, which means amending the soil in tree planting holes is often ineffective and sometimes destructive.

However, trees can be planted with as much as ⅓ of their root balls above the soil line and loam soil and organic matter can be added on top of the existing soil to establish them on marginally well-drained soil.

Gardens and beds where shrubs are planted can be amended by adding organic matter such as compost, peat and composted sludge. 

Sand is ineffective in improving drainage when less than 50 percent of the soil is composed of sand, which makes it a poor soil amendment.

  1. Hi Sara,
    Thanks for the article. Do you know of any seed or tree planting programs that offer these trees etc. That you mentioned? I’d like to plant diversity to prepare for future climate changes.

    • Stephanie,

      I’m not sure where you’re at, but Ohio Prairie Nursery ships seed mixes for specific soil conditions and the soil and water conservation district in your county likely holds an annual native plant sale, tree sale or both. Those are the places I would start. Best of luck to you!
