20 September

VEGETABLE PATCH : Root vegetables shine in today’s cool autumn soil! Harvest mature beetroots by gently loosening the soil with a garden fork before lifting – those with 7-10cm diameter offer perfect sweetness and texture. / Prepare new beds for garlic by incorporating 2kg of well-rotted compost per square meter, working it 25cm deep to improve drainage. / Direct sow winter radishes like ‘Black Spanish’ and ‘Daikon’ 1cm deep in rows 20cm apart, thinning to 10cm spacing once seedlings emerge. / In Mediterranean regions, plant turnips and swedes now for winter harvests – elsewhere, protect with cloches if frost threatens.

LANDSCAPING : The slanting autumn light reveals where perennial divisions will benefit your garden most. Mark ornamental grasses ready for division after flowering finishes – varieties like Miscanthus and Pennisetum benefit from rejuvenation every 3-4 years. / Dig and divide overcrowded iris rhizomes, replanting the healthiest outer sections with the rhizome just visible at soil level. / Prepare planting holes for bare-root roses arriving next month by digging 40cm wide and deep, incorporating bone meal at the base to encourage strong root development. / Collect ripe seeds from Echinacea, Rudbeckia and Helenium, storing in paper envelopes in a cool, dry place.

INDOORS : House plants sense the seasonal shift in light quality. Gradually reduce watering frequency for succulents and cacti as days shorten, allowing soil to dry completely between waterings to prevent root rot. / Move citrus plants to bright windowsills, turning pots weekly to ensure even growth. / Check African violets and begonias for crowding – divide congested plants using a sharp knife, ensuring each section has adequate roots and leaves. / Pot up amaryllis bulbs for Christmas flowering, leaving the top third exposed above the soil surface.
