Following weeks of intense heat and dry spells, the UK is experiencing a welcome shift with cooler temperatures and rainfall. However, experts caution that this relief is insufficient to fully counteract the prolonged dry weather that has led to drought declarations in several counties. Gardeners are now advised to focus on recovery and future-proofing their outdoor spaces.
Water Management
Experts emphasize smart watering practices, especially with ongoing hosepipe restrictions. Cheryl Harper, Managing Director of Greensleeves Lawn Care, suggests utilizing rainwater collected in water butts or safely reusing greywater from household activities. Watering should occur in the early morning or late evening to minimize evaporation, with a focus on the driest areas. Jonathan Davis, a grass expert at Lawnsmith, recommends infrequent, deep watering sessions, two to three times per week, as more effective than daily light sprinkles. While lawns may show signs of regrowth within 10 to 14 days of consistent watering, full recovery can take two to four weeks.
Soil and Mulch
Improving soil's moisture retention is crucial. Applying a two to three-inch layer of mulch, such as compost, bark chippings, or well-rotted manure, helps keep the soil damp, regulates temperature, and suppresses weeds, according to Andy Simms of MyBuilder.com and David Denyer, a florist and gardening expert at Eflorist. For compacted soil, particularly in dry patches, gently aerating with a garden fork can create channels for water and air to penetrate deeper.
Lawn Care and Decking
Homeowners are advised against cutting heat-stressed grass too short, as this can deplete its remaining moisture. Cheryl Harper suggests raising mower blades to their highest setting or pausing mowing until healthy green shoots reappear. Leaving fine grass clippings on the lawn can act as a natural mulch, shading the soil. For sun-damaged wooden decking and furniture, Jimmy Englezos, a DIY expert at Ronseal, recommends cleaning with a stiff brush, applying a decking restorer, and allowing the wood to dry completely before applying oils, stains, or paint. This process can take up to two days after restoration.
Future-Proofing and Plant Selection
With extreme weather events becoming more common, experts suggest adopting a 'Mediterranean' gardening approach. Andy Simms recommends plants that thrive in sunny and dry conditions, such as olive trees, lavender, and camomile. David Denyer endorses options like rosemary, salvias, sedums, agapanthus, verbena, and yucca, which offer color and interest while tolerating dry spells. This shift in approach aims to prepare gardens for increasingly unpredictable weather patterns, with experts believing this inspiration from Mediterranean gardening will be significant by 2027.
