Hi there, I'm Dave Thompson, your friendly neighbourhood gardener from Staffordshire. With over 15 years of digging in the dirt, I've come to appreciate the versatility of barrel planters. Whether you're working with a modest courtyard in the Midlands or a sprawling garden, these rustic containers can add charm and functionality to your space. Let's dive into the best plants to grow in barrel planters.

Quick Answer

Barrel planters are ideal for growing herbs like rosemary and thyme, ornamentals like lavender, and small fruit trees such as dwarf apple trees.

Choosing the Right Plants

When selecting plants for your barrel planters, consider the size of the planter and the available sunlight. In the UK, our weather can be a bit unpredictable, especially here in Staffordshire, so choose plants that can handle a mix of sun and rain.

Herbs

Herbs are a fantastic choice for barrel planters. They thrive in the well-drained conditions of a raised container and are easy to maintain. Here are my top picks:

  • Rosemary: Loves full sun and is evergreen, providing year-round interest.
  • Thyme: Another sun-lover, perfect for culinary use.
  • Sage: Great for both cooking and attracting pollinators.

Ornamental Plants

For a splash of colour, consider ornamental plants. They can brighten up any gloomy Midlands day. Here are a few to consider:

  • Lavender: Provides colour, fragrance, and attracts bees.
  • Pansies: Hardy and available in a variety of colours.
  • Heuchera: Adds vibrant foliage and texture.

Fruit Trees

If you have a bit more space, why not try growing fruit trees in your barrels? Dwarf varieties are perfect for this purpose.

  • Dwarf Apple Trees: Compact and productive.
  • Dwarf Cherry Trees: Beautiful blossoms in spring.
  • Fig Trees: Prefer a sunny, sheltered spot.

Seasonal Planting Guide

Timing your planting can make a big difference in success. Here's a quick guide to help you:

Tips for Success

Here are a few tips to keep your barrel planters flourishing:

  • Ensure proper drainage by drilling extra holes if necessary.
  • Use quality compost mixed with grit for optimal soil structure.
  • Position your barrels to make the most of available sunlight.
  • Water regularly, especially during dry spells.

Maintaining Your Barrel Planters

Regular maintenance is key to keeping your plants healthy. Prune herbs to prevent them from becoming woody, and deadhead ornamentals to encourage more blooms. Keep an eye out for pests, particularly slugs and snails, which are common in the UK.

Frequently Asked Questions

Can barrel planters be used indoors?

Yes, barrel planters can be used indoors, but ensure they have proper drainage to avoid waterlogging. Choose plants that thrive indoors, such as herbs and smaller ornamentals.

How do I prevent my barrel planter from rotting?

To prevent rotting, line the inside of the barrel with a plastic liner or use a wood preserver on the exterior. Ensure adequate drainage.

What size barrel planter should I use?

The size depends on what you're planting. For herbs and small ornamentals, a depth of 30-40 cm should suffice. For dwarf fruit trees, aim for at least 50 cm in depth.
