All about alliums, clematis cuttings, summer care for succulents and the best plants for moths

This week on Gardeners' Corner, host David Maxwell dives into a lush tapestry of summer gardening wisdom, spotlighting the allium as Bulb of the Month—celebrated for its architectural beauty, diverse colors, and surprising utility beyond the garden. The episode reveals that alliums, once past their flowering peak, can have their floppy foliage removed immediately to keep borders tidy, a lesser-known tip that transforms their post-bloom appearance. Wildlife expert Katie Bell brings live moths into the studio, challenging the myth that moths are dull or night-only creatures, and reveals that day-flying species like the hummingbird hawk moth are drawn to tubular flowers such as red valerian and honeysuckle. She also champions the creation of 'moon gardens' with white, night-scented blooms to attract both moths and bats, urging gardeners to reduce light pollution and avoid pesticides. Meanwhile, Claire McNally guides listeners through propagating Clematis Montana using softwood cuttings or ground layering—ideal for preserving cherished family plants. The episode also explores the practical and poetic potential of garden design, from repurposed bicycle wheels to massive reclaimed stones, and offers a bold new perspective: dismantling show gardens after their brief life to free up creative space. Finally, a deep dive into succulent care reveals that even aggressive plants like agave and aeoniums thrive best with minimal intervention, especially during summer dormancy.
