New Zealand spinach is a tender, sprawling summer leaf crop that performs when true spinach runs to seed. Its branching stems carry fleshy leaves over a wide area, providing regular kitchen pickings in sunny weather. It is especially handy for warm, dry parts of a British garden.

When and how to sow

Soak the hard seed overnight before sowing. Start it indoors in April or May in module trays or pots, then plant out after the last spring frost; alternatively sow directly into warmed soil from late May. Give each plant 45 to 60 cm of space for trailing stems. Choose full sun and moderately fertile, free-draining soil, ideally improved with organic matter.

Care

Water during dry weather to encourage soft, productive shoots, especially after planting out. Once established, pinch growing tips to make plants bushier and guide stems away from paths. Keep the soil clear of weeds and mulch lightly to conserve moisture. It needs no support, but benefits from generous room to spread.

Common problems

This crop is generally trouble-free, although slugs may nibble low leaves and aphids can gather on young tips. Leaf spots are more likely where plants are crowded or foliage stays wet. Space widely, water at soil level, remove damaged leaves and clear old growth once frost finishes the crop.

Harvest

Begin taking leafy shoot tips when plants are well established and growing strongly, usually from midsummer. Snip short lengths of young stem with their leaves, rather than stripping one plant bare. Pick regularly for a cut-and-come-again supply. Growth ends with autumn frosts, so gather remaining tender shoots beforehand.
