Sow Yellow Rattle Now + Deadhead Dahlias for Weeks More Flowers

Keep your garden blooming into autumn. Learn precise deadheading, sow yellow rattle to start a wildflower meadow, and plant elephant garlic the right way. As days shorten, plants push energy into seeds and flowering slows. We show exactly where to cut out finished canna flower spikes at the base so the plant’s energy returns to fresh buds. The same principle works for dahlias and tithonias, keeping borders in color for weeks. It is also garlic-planting time. See how to plant elephant garlic properly: pointy end up, clove set deep with roughly a clove’s depth of soil above it, and spaced about 8–9 inches apart. It can reach around three feet tall and needs winter cold for vernalization to form proper cloves. In the orchard, we begin a wildflower meadow rich in pollen and nectar for bees. Learn how to scarify turf hard to expose soil, then sow a tailored mix plus extra yellow rattle (the meadow maker) at about 1.5 g per square metre before the end of October. Press seed in with a mower roller and mow short a couple of times before winter. Expect no visible change until spring, then a gradual transformation over several years. Carol tours East Leach House where early autumn glows: fiery dahlia ‘David Howard’ with heleniums, blue drifts of asters with Geranium ‘Rozanne’, scented clematis ‘Cassandra’, and vivid ceratostigma lighting up the borders. In Glasgow, Francis meets Ewan Sutherland, whose hands-off wildlife garden features a green-roof shed, an ingenious bug hotel, a wasp-friendly feeder, creative weed control, and unusual edibles like pignut. Mark revisits Nyman’s to see rainwater harvesting, groundwater recycling, and a tough-love watering strategy that builds resilience. Gardener Kirsten Kelly’s South African meadow beds thrive through heat with minimal irrigation thanks to raised dunes and careful plant choice. Back at Long Meadow, we take stock of the Paradise Garden, cutting back flopping stipa to stop it smothering neighbors and celebrating stalwarts like verbena. We also drop into a forest garden at East Harp Tree that layers fruit and nut trees, shrubs and perennials for year-round harvests. Plus, a Pembrokeshire garden turns bog and rock into beauty by embracing its limits, even converting a surprise surface well into a lush bog bed and repurposing a salvaged still as a water feature. Weekend jobs: lightly dome-prune shrub roses now, aerate compacted lawns with a fork then rake out moss and thatch, and plant biennials such as wallflowers, sweet williams, forget-me-nots and foxgloves. #yellowrattle #wildflowermeadow #deadheading #elephantgarlic #autumngardening #wildlifegarden #Nymans #GardenersWorld
