Tetragonia, or New Zealand Spinach, requires a medium level of care. It prefers full sun, well-drained soil, and moderate to high water levels. The optimal growing temperature range is between 60°F and 85°F. Common challenges include susceptibility to leaf spot and mold diseases, along with pests like aphids and caterpillars. Tetragonia thrives in summer and requires less water in winter. In colder regions, it becomes dormant in winter, requiring protection from frost. Overall, careful monitoring and seasonal adjustments are key to its healthy growth.
