Your wood retaining wall has to be properly maintained in order to last longer and remain appealing.
To make sure it endures, remember these suggestions:
At least twice a year, visually examine the retaining wall.
Every few years, use a protective sealer or stain to increase the wood's resilience to moisture, UV light, and pests.
Examine the backfill material for any indications of blockage or erosion when cleaning the drainage pipe.
Maintain the correct grade and slope to stop water from building up behind the wall.
Large trees and plants shouldn't be planted too next to the wall since their root systems might damage it.
