Just like most living things, your plants, shrubs and trees can only handle so much water.
If a flash flood hits your garden occasionally, your plants should rebound. But if your garden keeps flooding when it rains or is often affected by major floods, that’s a problem.
Learn how to fix that, and moving forward, replace damaged plants, trees and shrubs in your garden with plants that thrive in wet soil.
Garden Flooding Problems and Solutions–Plants, Trees and Shrubs that Grow in Wet Soil
How can I tell if a flood did damage to the trees, plants or shrubs in my garden?
Plants that sit in saturated soil, called waterlogged soil, will drown after a week because their roots can’t access oxygen–only water.
If you see water pooling in your yard, poke deep holes in the ground when the water begins to drain. Try not to step on the waterlogged areas much when they’re wet, or you’ll worsen the problem.
Then, monitor your trees’ health for the next few months to see if there’s any long-term damage. Keep your eye on oaks, hickories, lindens and some maples. They're more likely to have problems since they’re not used into flood conditions.
Look for the following signs of tree trouble after a flood:
- Broken limbs
- Exposed roots
- Leaning or unstable trees
- Gouges in the trunk
- Premature fall color
- Wilted or discolored leaves
- Dieback of branches
