New Zealand Spinach is a warm-season vegetable in the Aizoaceae family, grown either from a direct sowing or from transplants. It wants full sun, though it tolerates a little afternoon shade in hot regions and steady, even moisture. From sowing to first pick is about 50–70 days. It shrugs off a light frost but a hard freeze will damage it.

Grower’s note: A sprawling, drought- and heat-tolerant stand-in for spinach through summer. Soak the hard seed 24 hours before sowing. Pick the tender shoot tips and it keeps branching; it self-seeds freely. Blanch briefly before eating to cut the oxalates.

Sowing

Sow about 0.75″ deep, into soil between 65–85°F — germination is quickest near 75°F. It is slow and often erratic to germinate (10–21 days). For an early crop, start seed indoors about 4 weeks before your last spring frost and grow it under bright light.

Spacing & layout

Give each plant about 12″ along the row with roughly 24″ between rows. On a square-foot grid that is 1 per square foot. Allow at least 12″ of loose, workable soil for the roots. It grows well in containers at least 12″ deep.

Fitting it to your season

New Zealand Spinach needs roughly 50–70 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
