VEGETABLE PATCH : A descending moon in a leaf sign — the kind of day that old kitchen gardeners called “green gold” for a reason. Sow autumn spinach (Spinacia oleracea ‘Matador’ or ‘Medania’) in rows 25 cm apart, seeds 2 cm deep and thinned to 15 cm once germinated — the descending energy encourages strong leafy growth without bolting in the shortening days / Direct-sow land cress (Barbarea verna) in a shaded corner of the bed, scattering seed thinly and raking in lightly; it will fill gaps left by summer harvests and provides peppery leaves well into autumn / Transplant Chinese cabbage (Brassica rapa subsp. pekinensis ‘Kasumi’ or ‘Bilko’) seedlings raised under cover, spacing plants 35 cm apart and watering in with 0.5 litres per plant — firm the rootball gently to eliminate air pockets / Cut mature Swiss chard (Beta vulgaris ‘Bright Lights’ or ‘Fordhook Giant’) stems at the base with a clean knife, leaving the central crown intact so a second flush of leaves develops over the next three weeks.
INDOORS : Summer heat builds up quickly on south-facing windowsills, and leafy herbs notice it first. Repot overcrowded mint (Mentha spicata or Mentha × piperita) into a pot one size larger — 14 to 16 cm diameter — using a loam-based compost mixed with 20% perlite for drainage; roots escaping the drainage holes are your clearest signal it’s time / Harvest outer leaves of indoor lettuce (Lactuca sativa ‘Little Gem’ or ‘Tom Thumb’) grown in deep trays, taking no more than one-third of the plant at each cut to keep production going / Mist the foliage of parsley (Petroselinum crispum) and chervil (Anthriscus cerefolium) lightly in the morning — both appreciate humidity when indoor air turns dry under summer sun, and consistent moisture reduces the risk of premature bolting.
