Things to consider
Malabar spinach is a familiar leafy vegetable; eat only washed, cooked leaves and tips. The ripe fruit contains a purple-red juice used as food colouring and should not be eaten in quantity.
How to grow and care for it
Planting and pot
Soak seed in warm water for 24 hours then sow; space 30–45 cm apart next to a trellis at least 1 m tall (vines reach 3–5 m in one season so the support must be strong). Humus-rich, draining soil at pH 6.0–6.7 with compost mixed in.
Light
Full sun (about 6–8 hours) with afternoon shade in very hot climates; growth is slow below 27 °C and stops below 16 °C.
Watering
Keep soil evenly moist and mulched; letting it get too dry makes the plant flower and cuts leaf production.
Feeding
Balanced fertilizer every 2–3 weeks or all-purpose organic every 4–6 weeks; add aged compost or manure at planting.
Pruning
Pinch tips to branch and yield more foliage; cut overlong vines to prompt new growth; remove flowers to prolong leaf production.
Propagation
Cuttings of healthy stems with at least 2 nodes in water or moist soil (spring or early summer best); or seed soaked in warm water for 24 hours.
Pests and common problems
Spider mites, aphids and whiteflies; powdery and downy mildew; leaf miners in hot dry spells; leafhoppers. Keep airflow and remove diseased leaves.
For a bigger harvest
For plentiful greens: enough sun, a strong trellis, moist humus-rich soil, steady feeding, pinching and removing flowers. Pick leaves and young tips continuously from about 60 days after planting.
