Beautiful urns with diverse plants suitable for UK gardens

Urns can be a striking addition to any garden, offering a touch of elegance and height. As a gardener in Staffordshire, I've had the pleasure of experimenting with various plants in urns over the years. The secret lies in selecting the right plants that not only thrive in our climate but also complement the aesthetics of your outdoor space.

Quick Answer

Choose plants that suit your urn's location, such as shade-loving ferns or sun-loving geraniums, and ensure good drainage and appropriate soil mix.

Considerations for Choosing Plants

Before you begin planting, it's crucial to consider the location of your urn. Will it be in a sunny spot or a shaded area? This will largely determine the types of plants that will thrive there.

In the Midlands, we experience a variety of weather conditions, so opting for hardy plants that can withstand occasional frost or heat is wise.

Sun-Loving Plants

  • Geraniums: Vibrant blooms that love full sun and provide long-lasting colour.
  • Lavender: Adds fragrance and attracts pollinators, perfect for sunny spots.
  • Petunias: Ideal for creating a cascade of colour over the sides of urns.

Shade-Tolerant Plants

  • Ferns: With their lush green fronds, ferns bring texture and interest.
  • Hostas: Known for their striking foliage, they thrive in partial shade.
  • Begonias: Offer vibrant flowers and thrive in shaded areas.

Planting and Maintenance Tips

Once you've chosen the right plants, the next step is to prepare your urn. Ensure it has adequate drainage holes to prevent waterlogging, which can damage roots. A good mix of compost and soil will provide the nutrients needed for healthy plant growth.

Regular watering is essential, especially during dry spells common in our summers. However, avoid overwatering as this can lead to root rot, particularly in clay-based soils.

Frequently Asked Questions

Can I use any soil in my urn?

It's best to use a mix of potting compost with added grit for drainage. This ensures the roots have enough air and don't become waterlogged.

How often should I water plants in urns?

During the warmer months, you may need to water daily, especially if the urn is in full sun. In cooler weather, reduce watering frequency but ensure the soil doesn't dry out completely.

What size urn should I use?

The size depends on the plants you're growing. Larger urns are ideal for mixed plantings or larger species, while smaller urns suit compact plants or single species displays.
