Following a punishing summer characterized by record-breaking heat and a severe lack of rainfall, gardeners are seeking ways to salvage their plants and adapt their approaches for future dry spells. The summer of 2026 has been described as "brutal" and "a horror show" by many, with some reporting physical strain from the increased effort required to keep gardens alive. Experts note a significant rise in injuries, humorously dubbed 'watering can-itis' by physiotherapists, from the arduous task of manually watering plants.
The extended drought, the driest in 190 years, has led to a declared drought across 70 percent of England and all of Wales, prompting a reassessment of traditional gardening practices. Many are questioning the environmental and energy costs associated with maintaining water-intensive plants like hydrangeas, azaleas, rhododendrons, petunias, and sweet peas. Even seasoned gardeners, such as Monty Don, are reconsidering their planting strategies to better cope with anticipated future droughts, suggesting a need for a "totally different palette" of plants.
Philippa Burrough, whose garden in Essex is known for its drought-tolerant species, described the summer as "horrific." She reported losing a well-established beech hedge and noted that dahlias, usually a strong performer, were "terrible." However, she found that certain plants, including gaura, sedums, ornamental grasses, and surprisingly, some varieties of roses—traced back to Middle Eastern origins—fared well. Burrough is embarking on a two-year project to re-landscape her eight-acre garden with more drought-tolerant species and to incorporate shade belts to mitigate extreme heat.
Reviving Lawns and Borders
Parched lawns, appearing straw-like, are likely dormant rather than dead. Grasses conserve moisture by turning brown, but their roots typically remain alive. Experts advise against immediate restoration efforts such as scarifying, which requires a strongly growing lawn, or reseeding, as grass seed germination demands significant watering. The recommendation is to let nature take its course, allowing the grass to revive naturally before a final pre-winter trim. For those considering removing lawns, it's noted that they absorb water better than hard surfaces and are more wildlife-friendly.
Autumn is presented as the ideal time for planting, particularly drought-tolerant species inspired by Mediterranean flora. This allows plants to establish deeper root systems before the summer months. Mulching with organic matter is recommended as soon as sufficient rain returns to help retain soil moisture and nourish plant roots. For gaps left by heat-stressed plants, drought-tolerant options like sedums, cistus, and lavender are suggested.
Recommended Drought-Tolerant Plants
Several plant types are highlighted for their resilience to heat and low water conditions:
- Sedums: Known as stonecrop or ice plants, their water-storing leaves make them exceptionally tough. Varieties like 'Autumn Joy', 'Red Cauli', 'Matrona', and 'Xenox' are recommended.
- Eryngiums (Sea Hollies): These plants with striking, spiky flowers and cones thrive in sunny, well-drained sites and require minimal water once established. 'Big Blue', 'Neptune's Gold', and 'Steel Blue' are suggested.
- Catmint (Nepeta): With deep roots that help them survive hot summers, catmint becomes maintenance-free after its first year of watering. Compact varieties like 'Amelia' and larger ones like 'Six Hills Giant' are noted.
- Bearded Irises: A cottage garden favorite, these thrive in hot weather and come in a wide array of colors.
- Phlomis (Jerusalem Sage): This plant relishes hot conditions, with hooded flowers appearing from late spring until autumn. Yellow 'Phlomis russeliana', pink 'Phlomis italica', and 'Phlomis tuberosa Amazone' are options.
- Agapanthus: Adapted well to Britain's climate, they require a sunny spot and are very low-maintenance once established, producing large umbels of trumpet-shaped flowers.
- Agastache: Native to North America and Mexico, these members of the mint family are loved by pollinators and cope well with dry conditions, offering a long flowering season with aromatic spikes.
- Lavender: The quintessential Mediterranean plant, lavender requires full sun and well-draining soil, needing no watering once established. 'Hidcote' and 'Munstead' are popular varieties.
- Echinops (Globe Thistles): These plants with globe-shaped blue flowers are happy in any well-drained, sunny spot. Cutting them back after the first bloom can encourage a second flowering.
- Leucanthemum (Shasta Daisies): These have proven to be very resilient, producing flowers for extended periods with minimal watering. Varieties include 'Snowcap', 'Ox-Eye', 'Crazy Daisy', and 'Banana Cream'.
Shrubs that can withstand heat and drought once established include Gaura, Hebe, Rosemary, Perovskia (Russian Sage), Escallonia, Cistus (Rockrose), Caryopteris, Buddleia, Santolina (Cotton Lavender), and established Roses.
Autumn Action Plan
With the arrival of rain and no immediate frost, autumn offers an opportunity to revive gardens. Gardeners are advised not to despair if a plant appears dead; a quick check for green beneath the stem's surface can indicate life. Even if a mature plant shows no green, it may sprout anew from the base in spring. Pruning back brown stems and mulching are recommended.
Deadheading spent flowers on plants like cosmos and dahlias can encourage new blooms. Diluted tomato feed or seaweed fertilizer can boost flowering plants, especially those in patio pots that may have depleted nutrients. Tall plants and young trees should be staked against predicted autumn winds. Late-summer flowering plants like ornamental grasses, salvias, heleniums, and echinaceas are available at reduced prices and can fill gaps while also being suitable for overwintering.
Containers can be refreshed with autumn-appropriate plants such as heather, heucheras, cyclamen, and low-growing sedums. Regular watering is still necessary if rainfall has been insufficient, with particular attention to camellias developing new buds. Planning for the following year can begin by ordering hardy annuals like cornflowers and calendula, which can be sown in September to withstand winter and bloom in late spring or early summer.
