Head Gardener's Notes: High Summer 2026

The gardens are now moving through the height of summer and, after an exceptionally dry period, much of our attention has been focused on maintaining standards rather than making major changes. The lawns have inevitably lost some colour in places and growth has slowed compared to earlier in the season, but many of the borders continue to perform well despite the lack of rainfall, although the stress is showing on some of the less drought resistant plants.

Throughout May, June and July the team has concentrated on the continued upkeep of the formal areas. As is often the case, the work is not always dramatic, but it is essential; regular cultivation, hoeing, weeding and garden maintenance help keep these areas looking their best throughout the busiest visitor period of the year.

The dry conditions have meant that some seasonal tasks have required less attention than they might in a more typical summer. Instead, we have been able to focus efforts on detailed maintenance work within the beds and borders. The team has spent considerable time carrying out maintenance rounds, working through areas methodically and addressing the many small jobs that collectively make a significant difference to the appearance of the gardens.

A particular focus over recent weeks has been the Flag Garden and Italian Garden, both of which have featured regularly in our work schedules. These spaces are among the most visited parts of Penshurst Place and demand continual attention throughout the season.

July has also seen the annual clipping of the box hedging. This is one of the most recognisable summer gardening tasks and plays an important role in maintaining the structure of the formal gardens. Freshly clipped box provides a strong framework that supports the surrounding planting and reinforces the historic character of the garden.

Away from the public eye, the team has continued to support workshops, prepare areas for events and undertake the regular inspections and maintenance work that are essential to managing a historic garden of this size. While these tasks are less visible than planting projects, they are vital in ensuring that visitors can enjoy the gardens at their best throughout the season.

As we move towards late summer, our focus will remain on maintaining standards across the gardens while planning for the work that autumn will bring. Gardens are always changing, and one of the pleasures of this time of year is seeing how different areas respond to the season and the weather that each year brings. However, we will be very happy for some rain.
