Garden Experts Offer Tips for Autumnal Recovery After Record Heat

As the season shifts from record-breaking heatwaves to cooler, wetter weather, gardeners are being advised on how to bring their outdoor spaces back to life. Home improvement retailer Wickes has collaborated with a garden expert to outline five key steps for an "autumn reset" aimed at helping gardens recover from a summer of scorching temperatures and prolonged drought.

Clair Albone, Senior Category Manager for Gardens at Wickes, emphasized the critical nature of early autumn for garden maintenance. "Many people assume garden care stops when the weather cools down," Albone stated, "But early autumn is one of the most critical times of year for gardens. Taking a few simple steps now is the secret to helping your garden recover and thrive come spring."

Reviving Lawns

Following a summer of intense heat, the early autumn period is presented as an ideal time to address lawn care. While cooler temperatures and rain might suggest the end of strenuous garden work, the combination of warm soil and heavy rainfall can create conditions conducive to thatch, moss, and soil compaction. These issues can impede the flow of air, water, and nutrients to grass roots.

"Reviving grass in early autumn is crucial for achieving a healthy lawn by spring," Albone noted. She recommends scarifying or dethatching as a starting point to remove accumulated dead thatch, moss, and debris. For compacted areas, tools like the Wickes Carbon Steel Lawn Aerator can help loosen the soil, facilitating better root system access during the wetter months.

Maintaining the lawn height at approximately 4-5 cm is advised as the grass begins to recover, helping to protect it from harsh cold and promote growth in the spring. When mowing, it is important to avoid removing more than one-third of the grass blade at a time to prevent undue stress on the recovering grass.

Water Management and Soil Nourishment

Autumn's arrival signals an opportunity to harvest rainwater, creating a reserve for future dry periods. Albone highlighted the unpredictability of UK weather and the importance of preparing for drier conditions. A rainwater harvesting system, such as a Wickes 210L Water Butt, can store rainfall for later use on lawns and plants.

The summer's heat can leave garden soil hard, dry, and compacted, hindering water penetration when autumn rains fall. Introducing organic matter in autumn is suggested to break up compacted soil, enhance drainage, and replenish nutrients. This process provides a healthier foundation for plants as they enter winter. Albone explained that after a hot summer, topsoil can become an "impenetrable, concrete-like crust," potentially leading to flash flooding during autumn rains. Adding nutrient-rich compost or farmyard manure in late autumn or early winter can improve soil structure. A layer of mulch is also recommended to suppress weed growth and prevent competition for water with recovering plants.

Experts advise against the immediate use of chemical fertilizers on stressed garden beds, as these can potentially harm plant roots. Instead, a focus on restoring soil moisture through slow, deep watering and the addition of organic matter is recommended. Gentle feeding can be considered once the soil is hydrated and plants show signs of recovery.

Plant Relocation and Furniture Protection

The cooler months are also presented as an opportune time to rethink garden layouts and relocate established shrubs and plants. As many plants enter dormancy, their growth slows, and their exposed roots experience less stress compared to transplanting during warmer, sunnier periods. It is advised to choose a day when the soil is neither frozen nor waterlogged, to dig widely to preserve the root ball, and to water thoroughly after repositioning.

Beyond the plants, protecting patio furniture from the wetter weather is also part of the autumn reset. Rain, damp leaves, and cooler temperatures can damage exposed furniture. Protective covers can help keep furniture dry and extend its lifespan through the autumn and winter months.

Pruning Considerations

While tidying the garden is important before winter, avoiding over-pruning is crucial. Albone cautioned that beds likely sensitive and dehydrated from the summer heat require a gentle approach. Deadheading spent flowers and removing completely dried or damaged stems are vital tasks, but cutting back healthy growth or heavily pruning stressed shrubs and trees should be postponed until spring.
