Are Whiskey Barrels Good for Plants? The Surprising Answer

Ever wondered if those old whiskey barrels collecting dust in the backyard could be repurposed for your garden? You're not alone. Many gardeners and whiskey enthusiasts alike have asked themselves the same question. After all, oak barrels were once used to age and mellow whiskey for years, imparting flavors of vanilla, caramel, and spice. It seems only natural that their wood might also benefit plants and soil in some way.

Introduction to Using Whiskey Barrels for Plants

Using whiskey barrels for plants may seem strange, but many gardeners swear by it. The barrels’ porous wood and lingering aroma can benefit plants in surprising ways.

Whiskey barrels allow for drainage and aeration, which most plants need. The wood absorbs excess moisture while still retaining some water for the roots. This creates an ideal balance of air and moisture for plant growth. Many plants, especially herbs and vegetables, thrive in whiskey barrels.

The barrels also impart a subtle flavor to the plants. As the wood ages, it releases compounds that give whiskey its distinctive taste. These compounds seep into the soil and get taken up by the plant roots, influencing the plant’s flavor and aroma. Gardeners report herb plants especially take on notes reminiscent of the whiskey once aged in the barrel.

If you want an inexpensive container with built-in drainage and the potential to enhance your plants’ flavors, give whiskey barrels a try. You can often find used barrels at liquor stores, wineries, and garden centers for a reasonable price. With the right plant and a little TLC, they can make a great home for your garden.

The Chemistry Behind Whiskey Barrel Planters

Whiskey barrels aren’t just for aging bourbon anymore. Turns out, they make great planters too. The wood in barrels has special properties that can benefit your plants.

The Chemistry

Barrel wood, like oak, releases compounds as it weathers that actually help your plants thrive. Tannins, for example, are natural fungicides that fend off disease. Lignins break down into simple sugars that feed soil microbes and your plants.

• Barrels also raise the pH of the soil, making it less acidic so more nutrients are available for your plants to absorb. The wood itself is porous, allowing for good air flow to the roots.
• As the wood ages, it develops more cracks and crevices for roots to wind their way through. Some gardeners even drill extra holes in the bottom of barrels to improve drainage and aeration.

Whiskey barrel planters are ideal for small trees, shrubs, veggies, or flowering plants. The next time you’re at the garden center, consider upcycling a barrel into a planter. Your plants will thank you for it!

Potential Drawbacks of Whiskey Barrel Planters

Potential Drawbacks of Whiskey Barrel Planters

Whiskey barrels may seem like a charming planter, but there are a few downsides to consider before using one in your garden or home.

The wood in whiskey barrels is treated to impart flavor to the alcohol, and some of the chemicals used can leach into the soil, potentially harming plants. While many plants will still thrive, the leaching may stunt the growth of more sensitive varieties. It’s best to line the barrel with a sealant before planting to prevent contamination.

Barrels also retain moisture and can lead to root rot if not properly drained. Drilling extra holes in the bottom and filling the bottom third with gravel or perlite will improve drainage and aeration for the roots.

Whiskey barrels are difficult to move once filled and planted, so choose a permanent spot. Their weight means they can be unstable, posing a risk of tipping over if bumped or on uneven ground. Securing barrels to stakes in the ground or a wall can prevent accidents.

Though charming, whiskey barrels may require extra work to become suitable, thriving planters. With some modifications and the right plant choices, barrels can make an attractive garden feature, but go into the project aware of their potential downsides.

Best Plants for Whiskey Barrel Planters

Mint

Mint is a perfect herb for whiskey barrel planters. Its refreshing aroma complements the lingering scent of bourbon in the wood. Mint grows quickly and spreads easily, so plant it by itself. Choose peppermint or spearmint—both do well and can thrive for years.

Lavender

The delicate purple flowers of lavender pair beautifully with whiskey barrels. Lavender thrives in hot, dry conditions, so the slight moisture-wicking effect of the barrels is ideal. English lavender is the most common type, with a classic floral scent. Once established, lavender requires little maintenance beyond annual pruning.

Rosemary

Rosemary is a fragrant, drought-tolerant herb that loves the free-draining environment of whiskey barrels. Its piney aroma mixes nicely with notes of oak and vanilla. Rosemary can grow quite large, so choose a dwarf cultivar like ‘Arp’ or ‘Barbecue’ and prune it regularly to control its size.

Thyme

Thyme is one of the most versatile herbs for whiskey barrel planters. Its earthy, herbaceous scent complements bourbon flavors. Thyme comes in many varieties, from upright English thyme to mat-forming creeping thyme. All do well in barrels and require little maintenance. Thyme retains its flavor when dried, so you can harvest some to use in cooking.

Preparing Whiskey Barrels for Gardening Use

Once you've acquired an used whiskey barrel, you'll need to prepare it before using it as a planter. The aging process that gives whiskey its distinctive flavor also leaves behind compounds that can be harmful to plants. Follow these steps to get your barrel garden-ready:

• Clean the barrel thoroughly. Scrub the inside with a diluted bleach solution to kill any bacteria and rinse well with water. Let it dry completely to avoid mold growth.
• Seal the barrel. The porous wood will leach moisture from the soil and your plants won't thrive. Apply 2-3 coats of sealant, like polyurethane, to the inside of the barrel. Water-based is a good choice since the barrel will be used for gardening. Let it dry as directed between coats.
• Add drainage holes. Whiskey barrels don't have built-in drainage, so you'll need to drill several holes in the bottom, about 1/2 inch in diameter. This allows excess water to drain and prevents root rot. Place a saucer under the barrel to catch drips.
• Consider a liner. As an extra precaution, you can put a plastic liner or liner bag in the barrel before adding soil. This prevents the sealant chemicals from leaching into the soil and provides an extra moisture barrier. Cut slits or holes in the bottom of the liner for drainage.
• Add fresh soil and compost. Fill the barrel about 2/3 full with a mixture of potting soil and compost or composted manure. Whiskey barrels have a lot of room for roots to grow. The compost will provide nutrients to get your plants off to a good start.

With some TLC, an old whiskey barrel can make a wonderful planter for shrubs, flowers, herbs, and vegetables. Taking the time to properly prepare the barrel will help ensure your plants thrive.

Filling and Caring for Whiskey Barrel Planters

Once you have your whiskey barrel planters, it’s time to fill them up and get planting. Here are some tips for caring for plants in whiskey barrels:

Drainage

Whiskey barrels don’t have drainage holes, so you’ll need to drill some in the bottom before adding soil. Aim for 8 to 12 holes that are at least 1/2 inch in diameter. This will allow excess water to drain and prevent root rot. You can also place a few inches of gravel at the bottom of the barrel before adding soil for extra drainage.

Soil

Use a well-draining potting mix, not regular garden soil. A mixture of perlite, compost, and potting soil works well. Fill the barrel about 2/3 full with the potting mix. For smaller barrels, you may need to fill it a bit higher, but be sure to leave some space at the top for watering.

Plants

Choose plants that can tolerate the confined space of a barrel, such as dwarf shrubs, succulents, herbs, or annual flowers. Dwarf azaleas, lavender, petunias and dwarf spirea all do great in whiskey barrels. Make sure the plants you choose are suitable for your climate and the amount of sun the barrel will receive.

Watering

Check the moisture level of the soil regularly and never let it completely dry out. Water thoroughly until water flows out the drainage holes. The limited soil volume means barrels can dry out quickly, so you may need to water more often, especially in hot or dry weather.

Fertilizing

During the growing season, fertilize the plants in your whiskey barrels every few weeks. Use a balanced, all-purpose fertilizer and follow the directions on the product packaging. Fertilizer will help your plants grow healthy and full.
