New Zealand Spinach problems — and how to fix them

New Zealand Spinach (Spinacia oleracea 'New Zealand') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Poor germination

Hard seed coats inhibit germination — soak seeds in warm water for 24 hours before sowing and plant after soil warms to at least 15°C (60°F). Cold soil is the most common cause of germination failure.

Frost damage

Frost-tender — even light frost (-1°C/30°F) kills plants. Do not plant out until all frost risk has passed. In short-season climates, start indoors 3–4 weeks before the last frost date.

Slow establishment

Growth is slow in cool spring conditions. Once temperatures consistently exceed 18°C (65°F), growth accelerates dramatically. Patience in spring is rewarded with prolific summer production.
