As summer temperatures continue to rise, gardening experts are sharing essential tips to help protect plants and lawns from prolonged periods of hot, dry weather. Michael Griffiths, author of "The Easy Garden," emphasizes that proactive, simple steps can ensure gardens remain healthy even during heatwaves.
Watering Strategies
Experts recommend watering plants during cooler parts of the day, either early in the morning or late in the evening, to minimize evaporation. Deep watering, which encourages stronger root growth, is advised over frequent light sprinklings. For potted plants, a method involving soaking them in water for about an hour until the compost is fully saturated is suggested. This ensures the soil is thoroughly rehydrated, not just the surface.
Providing Shade and Mulching
Plants, particularly those in pots or delicate species like young shrubs, may require temporary shade during the hottest parts of the day. Options include using garden fleece, shade cloth, umbrellas, or strategically placed containers. Applying a layer of mulch, such as bark, compost, or well-rotted manure, around plants is another key technique. Mulch helps retain soil moisture, suppress weeds, and regulate soil temperature, reducing the need for frequent watering.
Lawn Care in Hot Weather
Maintaining lawns during summer involves cutting them less frequently but with mower blades set higher. Longer grass helps retain moisture and protects roots from drying out. Experts advise against mowing during the peak heat of the day, opting for early morning or evening. A summer lawn fertilizer can provide a final feed before autumn, but late-season feeding should be avoided to prevent excessive winter growth. While lawns may appear brown during dry spells, this is often a natural drought response and grass typically recovers with rain. For those aiming to keep lawns green, one deep watering per week is recommended to encourage deeper roots. Newly laid turf requires more intensive watering, initially once or twice daily for the first two weeks, then gradually reduced.
Plant Maintenance and Pest Control
Deadheading, or removing faded flowers, encourages plants to produce more blooms rather than focusing energy on seed production. This practice is beneficial for repeat-flowering varieties such as roses, dahlias, lupins, peonies, cosmos, and salvias. Trimming geraniums and delphiniums can also promote fresh growth and subsequent flowering. Regular pruning and feeding can revive hanging baskets. Experts also caution against fertilizing drought-affected plants or dry soil, as it can cause 'burning.' It's advised to water thoroughly before feeding and to avoid over-fertilizing during extreme heat. Hot weather can also encourage pests like aphids and slugs. Regular inspection of plants allows for early detection and management of infestations. Encouraging natural predators and proper watering can help control pest populations without relying heavily on chemicals. For ant nests, sweeping away soil mounds and using deterrents if necessary are suggested.
Barbecue Care
Summer is also barbecue season, and experts recommend regular maintenance for outdoor cooking equipment. Cleaning grills after use and checking gas connections or charcoal trays can extend their lifespan. Clearing fallen leaves and debris around the barbecue area is also advised.
