How to Plant New Zealand Spinach

Spinach grows and thrives in home gardens around the country, but grows best in cool, moist, early spring weather. New Zealand spinach, on the other hand, grows best in warm, frost-free weather and stays productive through the summer season. Plant this frost-sensitive annual vegetable in mid-spring with rich soil and good nutrition for summer and fall spinach harvests.
