VEGETABLE PATCH : The ascending waning crescent keeps sap moving upward into stems and leaves — a solid window for leafy crops that deserve your attention today. Sow spinach (Spinacia oleracea ‘Matador’, ‘Medania’) in drills 1.5 cm deep, rows 25 cm apart; thin later to 8 cm and expect germination within 7–10 days in warm spring soil / Direct-sow Swiss chard (Beta vulgaris ‘Bright Lights’, ‘Fordhook Giant’) in rows 35 cm apart at 2 cm depth — each seed cluster can produce two or three seedlings, so thin to the strongest at 5 cm tall / Transplant celery (Apium graveolens ‘Golden Self-Blanching’) and celeriac (Apium graveolens var. rapaceum ‘Monarch’) seedlings started under glass, setting them 30 cm apart with the crown just at soil level; water in with 0.5 litres per plant to settle roots / Check pak choi (Brassica rapa subsp. chinensis ‘Joi Choi’) and mizuna (Brassica rapa var. nipposinica) sown earlier this week: thin to 15 cm apart so each plant has room to develop full, tender leaves without bolting / On heavy soils, incorporate a handful of sharp grit per planting hole before setting out celery to improve drainage and prevent crown rot over wet spells.
INDOORS : Seedlings of basil (Ocimum basilicum ‘Genovese’, ‘Red Rubin’) raised on a warm windowsill are ready to pot on once their first true leaves are firm and fragrant. Move each into a 9 cm pot filled with peat-free multipurpose compost, burying the stem just up to the lowest leaf pair to encourage a stocky habit / Aubergine (Solanum melongena ‘Moneymaker’, ‘Listada de Gandia’) plants under glass benefit from a liquid feed of balanced tomato fertiliser at half strength (5 ml per litre) now that flower buds are forming — potassium at this stage supports strong cell walls and better fruit set later / Check the undersides of cucumber (Cucumis sativus ‘Marketmore’, ‘Passandra’) leaves for the first signs of red spider mite: a fine misting of the foliage with plain water raises humidity and makes conditions less hospitable for the pest without reaching for chemicals.
