Can Plants Solve Houston Backyard Drainage Problems?

Plants don't absorb heavy rainfall fast enough to prevent flash flooding in Houston. Grass is the best short-term uptake, but for 30-minute deluges, you need engineered drainage: regrade to direct water away, install area drains (NDS boxes) piped to street, or build a dry well (fabric-lined gravel pit) to infiltrate runoff.

For erosion control, groundcovers help. But volume management requires pipes, swales, or dry wells—not plants. Clean gutters and leaf guards are step one. Step two: move water away from the house structurally.
