What are the characteristics of New Zealand Spinach?
New Zealand is a hardy leafy green vegetable with wonderful nutrition. Its soft leaves are slightly thick and grow along the stems. They have an oval to triangular shape with a pointed tip. Green leaves look shiny due to tiny salt-retaining hairs on their surface, known as salt bladders or trichomes. Such hairs hold additional salt, which allows a plant to grow well on salty soil while still performing photosynthesis. The older the plant is, the more it accumulates salt, making the leaves taste bitter and salty. Similarly, it produces small flowers in the leaf axils which later turn into the distinctive four-pointed fruit.

On the other hand, New Zealand Spinach is the opposite of regular spinach when it comes to growing conditions. Unlike common spinach, it does well only in warm weather and fails miserably in cool temperatures.
Nutritional Benefits of New Zealand Spinach
- New Zealand spinach is rich in calcium for strong bones and teeth, vitamin A for healthy organs, vitamin E to reduce inflammation, and vitamin C to boost your immune system.
- It also contains vitamin K so that wounds will heal faster and iron to make hemoglobin for the carriage of oxygen in the blood.
- Apart from these nutrients, New Zealand spinach is packed with manganese, folic acid, B-complex vitamins, Phosphorus, and riboflavin.
- However, it does have a high content of oxalates in the form of oxalic acid, which can be harmful. These may be reduced by cooking the leaves to minimize possible risks.
Uses of New Zealand Spinach
New Zealand spinach has a mild, slightly salty taste that is best when lightly cooked with tender leaves. To prepare, start by soaking the leaves in cold water for 30 minutes or blanch to reduce oxalates. Once ready, you may use it in pesto, sandwiches, pasta, and gnocchi. Its sturdy texture makes it a great substitute for regular spinach in frittata, casseroles, and stir-fries. Additionally, it pairs well with rich dishes flatbreads, and spanakopita. New Zealand spinach further adds flavor to soups, stews, and curries too.

Water
New Zealand spinach is renowned for its drought resistance but needs regular watering for the best flavor and vigorous growth. Especially during hot, dry summers, make sure the soil remains moist but not waterlogged.
Fertilizer

Pests and Diseases
Generally, New Zealand spinach is disease and pest-free. But it can occasionally affected by aphids and leaf miners. To prevent such pests, you may use organic insecticidal soap or neem oil which ensures good circulation and prevents fungal disease.
Harvest
Harvest New Zealand spinach when the plants are about 6-8 inches tall. Always get the outer leaves off first to allow the inner leaves to grow on. The plant will thereby remain fit and healthy with continuous production of leaves. Well, repeated harvesting not only supplies you with continuous fresh spinach but also urges the plant to form new leaves.

Seed Propagation
To propagate New Zealand spinach from seed, start by harvesting seeds in autumn. Look for brown seeds that are easy to collect. After gathering them, dry them thoroughly in a cool, dry, dark place. By March, they will be ready for planting. For quicker germination, soak seeds in water for 24 hours before planting. When planting, sow seeds about half an inch deep in loose, fertile soil enriched with organic matter. Space rows 3 feet apart and thin seedlings to 12 inches within rows. This spacing ensures plants have enough room to grow well. Following these steps will promote optimal growth for your New Zealand spinach.
Cutting Propagation
To propagate New Zealand spinach through leaf cuttings, start by selecting a healthy leaf. Use a sharp, clean knife to cut the leaf carefully so it stays whole and undamaged. Lay the leaf flat on slightly damp soil, making sure the bottom touches the soil. Keep the temperature around 25°C and give it bright, indirect light. With good care, you should see a new bud sprouting from the base of the leaf in one to two weeks.
