Step-by-Step Growing Guide
Malabar spinach (Basella alba — green form, Basella rubra — red-stemmed form) is the premier heat-season spinach substitute, thriving precisely when regular spinach bolts. It requires rich, well-draining, moisture-retentive soil with a pH of 6.0–7.0. Direct sow after the last frost when soil reaches 20°C minimum, or start indoors 4 weeks early. Soak seeds in warm water for 24 hours before sowing to break dormancy; germination is erratic without scarification. Sow 1 cm deep, spacing 30–45 cm apart at the base of a trellis at least 2 metres tall — Malabar spinach is a vigorous twining vine. Water frequently; the large succulent leaves lose significant moisture and the plant wilts dramatically under drought stress. Feed monthly with a nitrogen-rich fertiliser to promote leafy growth. In humid, hot summers it grows explosively. In cool weather below 15°C, growth slows dramatically and the flavour becomes slightly mucilaginous.
