Whisky barrel planters are a perfect way to add charm and growing space to your porch or deck but they tend to be heavy and difficult to move around. Plus, without proper drainage – they’ll rot out quickly and likely only last one growing season. This project will create an improved barrel planter that is lighter in weight and has a built-in drainage system to ensure longevity.

Time: 2.5 hours
Skill Level: Easy
Estimated Project Cost: $60.00 (as shown)
