Tales from the Walled Garden: August 2023 – How to Deadhead Perennials: A Gardener’s Guide for Hampshire Blooms

The Beauty of Late Summer Gardens in Hampshire

As summer threatens to draw to a close, Houghton Lodge Gardens is still bursting with life and colour. While some plants are turning to seed, others, like the vibrant Dahlias in our cut flower beds, are showcasing their best and providing a kaleidoscope of colour. But to ensure this beauty persists and even intensifies, there’s a gardening technique every enthusiast should master: deadheading.

Understanding the Art of Deadheading

Deadheading is more than just a routine task for any gardener; it’s a way to breathe new life into your perennials. For those unfamiliar, deadheading involves removing spent flowers or seed heads from plants. This not only enhances the aesthetic appeal of your garden borders but also promotes healthier growth and more abundant blooms, extending the summer colour across your gardens.

Why Deadhead?

Here are a few reasons why it is important:

  • More Blooms, More Beauty: By removing faded flowers, you encourage plants to produce more blooms instead of diverting energy to seed production. You will see all of the gardening team meticulously deadheading during August.

  • Seed Collection: For plants you wish to propagate, deadheading allows you to collect seeds at the right time such as those in the wildflower beds.

  • Garden Cleanliness: It helps in maintaining a tidy garden, free from potential disease and pest habitats.

Deadheading Techniques

While the concept is simple, the technique can vary based on the plant so it is best to check before you get happy with those secateurs:

  •  General Technique: For many perennials, simply pinching away the spent bloom with your finger and thumb does the trick.

  • Using Tools: For a cleaner cut or for tougher stems, gardeners can use secateurs or pinchers.

  • Specific Plants: For plants like agapanthus, it’s best to cut all the way down to the base of the stalk. However, for Dahlias, only the flower head needs removal.

August Tasks for Gardeners

With the end of summer approaching, here are some essential jobs to keep your garden in top shape:

  • Deadhead Regularly: Especially for perennials like Dahlias, this ensures continuous blooms into the start or autumn

  • Seed Collection: Harvest seeds from plants like sweet peas and aquilegia as they mature.

  • Manage Wildflower Beds: Once the seeds have scattered, it’s time to strim or mow your wildflower beds.

  • Savour the Moments: Don’t forget to take a moment to enjoy the serene beauty of your garden during these last days of summer.
