To begin building your whiskey barrel for planting, you’ll need to purchase a wood barrel. Look for barrels that are made from solid oak and have been treated with a food-safe coating—these will last the longest when exposed to outdoor elements. Consider researching reputable merchants online that offer wood barrels for sale in different sizes, shapes, and finishes depending on your preference. If possible, inspect the barrel before buying it to ensure there is no damage or cracks that could prevent water from leaking out of the container after it’s planted. Once you’ve acquired the necessary supplies, follow the steps below to create an attractive and functional whiskey barrel planter!
How to create whiskey barrels for planting
- Drill multiple drainage holes in the bottom of the barrel using a power drill.
- Apply a few coats of food-safe coating to the inside and outside of the barrel, allowing ample drying time between each coat. This will help protect the wood from water damage and rot.
- Fill the bottom of the barrel with a layer of gravel for additional drainage.
- Place potting soil into the top portion of the barrel until it is about 3/4 full, leaving a few inches of space at the top to accommodate plants as they grow larger over time.
- Plant desired flowers, vegetables, or herbs in the soil making sure to leave enough room for them to spread out once they reach maturity.
- Water regularly and add more soil or compost if needed to keep the plants healthy.
- Decorate the outside of the barrel with paint or wood stain to give it a unique look and protect it from weathering.
- Place your finished whiskey barrel planter in an area that receives full sun exposure, such as a deck or patio, for optimal growth and flowering results.
