Step-by-Step Growing Guide
Chia (Salvia hispanica) requires a long, warm, frost-free growing season of 120+ days. It thrives in well-draining, moderately fertile soil with a pH of 6.0–8.0 — it is remarkably tolerant of alkaline conditions unlike most crops. Loosen soil to 30 cm depth but avoid excessive fertilisation which delays seeding. Direct sow after last frost when soil reaches 16°C; chia seeds are tiny and should be scattered over a prepared seedbed, barely covered with 3 mm of soil, and gently firmed. Thin to 30 cm apart in rows 45 cm apart. Full sun is essential — shade dramatically reduces seed yield. Water during establishment and at flowering, but reduce once plants are established; chia is notably drought-tolerant. Apply a phosphorus-rich fertiliser at flowering to maximise seed set. In temperate climates, start indoors 6 weeks early and transplant carefully to extend the season.
