Heirloom / Open Pollinated New Zealand Spinach is a heat loving, short-lived, frost intolerant, perennial. We recommend soaking the Heirloom / Open Pollinated New Zealand Spinach Seeds for 24 hrs before planting, then direct sow seeds in full sun, covering with ½” of soil. Germination usually occurs in 7-10 days, but can be difficult. New Zealand Spinach plants like to sprawl, so you may want to trellis them to conserve garden space. Thin New Zealand Plants to 12-20″ apart.
