The answer to 'when to retaining wall installation' is that the best time to install a retaining wall is typically in the spring or fall when the weather is mild and dry. This allows the ground to settle properly and helps ensure the stability and longevity of the wall. Retaining walls can be installed year-round, but the spring and fall seasons are generally considered the optimal times for installation.
When planning a retaining wall project, it's important to consider factors like the soil conditions, the slope of the land, and the intended purpose of the wall. A professional landscaper can assess your property and provide recommendations on the best type of retaining wall and the ideal installation timeline.
