The Beechgrove Garden 2023 Episode 21: Bugs, Blights, and Other Garden Diseases

 

The popular BBC gardening program Beechgrove Garden returned for episode 21 of its 2023 season, providing helpful tips and inspiration for home gardeners. This episode focused on protecting plants from some of the most common garden pests and diseases.

Host Carole Baxter presented an informative “Back to Basics” segment all about identifying and treating various bugs, blights, and other issues that can damage garden plants. She covered potato blight, apple scab, and blackspot disease on roses—explaining what symptoms to look for, how these problems develop, and key ways to prevent and manage them.

Meanwhile, fellow hosts Diana Yates and Calum Clunie explored other gardening topics around the Beechgrove estate. Diana reviewed the progress in her small “vertical garden” area, demonstrating creative planting ideas for gardeners with limited space.

 

Learning to Spot and Stop Potato Blight

Potato blight, also called “tattie blight,” can quickly defoliate and destroy potato plants once it gets started. Carole explained that this fungal disease thrives during cool, wet, and humid weather. Dark brown lesions form on leaves, stems, and tubers. Entire plants collapse within days under severe infections.

The Hutton Criteria provides guidelines for predicting blight outbreaks. Carole noted that two consecutive days with temperatures above 10°C and relative humidity above 90% for over 6 hours are optimal blight-spreading conditions. Regularly checking potato foliage becomes critical during potential blight weather. At the first small spots, remove and destroy affected leaves immediately before the infection spreads.

For any plant with over 25% damaged tissue, Carole recommended cutting off all foliage at the base to stop the blight from reaching the tubers. While not a cure, this containment strategy can sometimes save the potato crop. Preventing blight in the first place involves practicing good crop rotation, planting resistant varieties like Orla and Sarpo, and earthing up plants to protect tubers.

 

Controlling Apple Scab Fungus

According to Carole, apple scab fungus thrives under the same rainy, humid conditions that encourage potato blight. Small, olive-colored spots appear first on leaves and fruit skin. Without treatment, these lesions enlarge, turning brown or black. They disfigure apples but remain shallow enough for safe eating after peeling.

Promptly removing and destroying infected leaves keeps damage localized. Resistant apple varieties like Discovery and Grenadier avoid the worst scab problems. Providing good air circulation through proper pruning creates an environment less hospitable to the disease. As with blight control, preventive autumn sanitation including quick removal of fallen leaves stops apple scab from overwintering and reinfecting trees the following spring.

 

Battling Blackspot Fungus on Roses

Among the most serious rose diseases, blackspot fungal infections create dark spots ringed with yellow on leaves. Entire leaves turn yellow then brown as blackspot spreads. Carole noted this fungus favors rainy conditions and vulnerable rose types like hybrid teas, floribundas, and climbers.

Along with immediately pruning off affected leaves and branches, growing blackspot-resistant rose varieties is key. Kordesia, for example, is a yellow floribunda rose with good disease resistance. Proper siting, care, and feeding also strengthen roses against infections. Good air circulation, well-drained soil, full sun, and avoiding excessive nitrogen fertilizer reduce blackspot’s foothold.

 

Other Key Garden Diseases

In addition to the fungal blights and blackspots, Carole touched on common bacterial and viral diseases that can damage gardens. Bacteria like Pseudomonas and Xanthomonas thrive in humid weather and create leaf spots, cankers, and dieback on roses, tomatoes, peppers, and other plants. Mosaic virus diseases stunt plant growth and mottling leaves. Aphid-transmitted rose rosette disease causes malformed flowers and stems. Careful inspection, hygiene, and propagation allow the containment of bacterial and viral pathogens.

 

Diana’s Small “Vertical Garden”

Co-host Diana Yates gave viewers a tour of her vertical garden section at Beechgrove, designed to maximize planting in a small 4×4 meter space. Vertical structures and containers leveraged vertical growing space for increased yields. Diana used colorful verbena, tall cosmos, climbing beans, and vining nasturtiums climbing on obelisks and trellises. She interplanted ornamentals like dahlias with edible crops in containers.

Though bunnies ate her lower-growing lettuces and strawberries, Diana’s vertical approaches kept other produce away from these garden pests. She advised leaving spent plants to stand for seed harvest, then following up with cool-weather crops like broccoli and greens. Protective covers or mesh can shield plants from late cabbage moths and butterflies. Diana’s segment provided many great tips for maximizing a small garden.

 

Key Steps for Improving Lawns

Beechgrove co-host Calum Clunie joined head gardener Scott Jackson to evaluate the estate’s lawn care needs. They observed how clover sprouting up signals low soil nitrogen. Regular mowing hadn’t met the lawn’s nutritional needs amid unpredictable weather patterns. Thatch buildup was also apparent in some areas.

Scott recommended overseeding thin patches as well as aerating, scarifying, and top-dressing the entire lawn this autumn. Well-timed fertilization with a phosphorus-potassium-rich blend will feed the lawn’s roots without spurring excess top growth before winter dormancy. Letting grass grow taller before final mowing allows it to store more energy. These steps will rejuvenate the lawn for a healthy spring green-up.

 

Reviewing Progress in the Walled Garden

Beechgrove’s George Anderson provided updates from his summertime garden projects. He highlighted rejuvenating a tired rock garden screen by amending soil, improving drainage, and planting hardy sedums and sempervivums. George also explained how pruning and training a rampant climbing rose prevents it from smothering nearby trees. In the vegetable garden, he demonstrated a novel method for curing, organizing, and hanging onions to store them for winter use.
