Plants grow 1 to 2 feet (.35-.61 m.) tall with a similar spread. There are several cultivars, some with smooth leaves and others with a savoy type leaf.

How to Grow New Zealand Spinach

A bright sunny location is best for growing New Zealand spinach. The plants do benefit from light shading during the hottest part of the day in southern regions.

You can even grow New Zealand spinach plants in containers. Keep soil moderately moist, but established plants can tolerate brief periods of drought.

New Zealand Spinach Care

New Zealand spinach has few pest or disease problems. Leaf miners can do cosmetic damage to the leaves. Other potential pests are cabbage worms, cabbage loopers, and aphids.

Drowning from poorly aerated soils and powdery mildew may occur. Make sure the soil is well draining, water from under the leaves and use row covers to protect leaves from pests. Mulch around the plants to prevent weeds, conserve moisture and keep soil cool.

Harvest when leaves are young, as older foliage may have a bitter flavor. You can remove just a few leaves or cut the plant back to the soil and let it come again. This is a really interesting, easy-to-grow green that can provide all the benefits of spinach well into the warm season.
