New Zealand spinach, also known as Tetragonia tetragonioides, is a versatile plant that can thrive in a variety of conditions. While it prefers full sun, it can also tolerate partial shade. However, it is important to note that New Zealand spinach may not grow as vigorously or produce as abundant a harvest if it is grown in shade compared to when it is grown in full sun.
In my personal experience, I have grown New Zealand spinach in both full sun and partial shade. When grown in full sun, the plants were more robust, with larger leaves and a higher yield. The plants also seemed to be more resistant to pests and diseases. On the other hand, when grown in partial shade, the plants were still able to survive and produce some harvest, but they appeared slightly weaker and less vigorous.
When considering growing New Zealand spinach in shade, it is important to choose a location that still receives a decent amount of sunlight throughout the day. Ideally, the plants should receive at least 4-6 hours of direct sunlight, although they can tolerate less if necessary. It is also important to ensure that the soil is well-drained and rich in organic matter, as New Zealand spinach prefers moisture-retentive conditions.
To compensate for the lack of sunlight in shade, you can provide additional support to the plants to prevent them from trailing on the ground. This can be done by using stakes or trellises to keep the plants upright. By doing so, you can help increase air circulation around the plants, which can reduce the risk of disease.
In terms of care, New Zealand spinach grown in shade may require more attention than those grown in full sun. Regular watering is essential to ensure that the soil remains consistently moist, as shade can sometimes lead to higher humidity levels. Additionally, applying a layer of mulch around the plants can help conserve moisture and suppress weeds.
While New Zealand spinach can tolerate some shade, it is best to provide it with as much sunlight as possible to promote optimal growth and harvest. If you are limited to a shady location, it is still worth giving it a try, but be prepared for potentially smaller yields and less vigorous plants compared to those grown in full sun.
