Share
Spring in New Zealand is the perfect season to clean out and refresh your hydroponic garden and make the most of your outdoor growing space. September brings longer days, milder temperatures, and the ideal environment for planting vegetables in a hydroponic tower. Whether you’re new to hydroponics or already have a thriving hydroponic system, now is the time to grow fresh, nutritious produce right at home.
Here are the top 10 vegetables to plant in your outdoor hydroponic tower this September, in New Zealand:
1. Lettuce
A true classic for any hydroponic garden, lettuce is fast-growing, space-efficient, and perfect for continuous harvesting. Varieties like cos, buttercrunch, and iceberg thrive in hydroponic towers, giving you crisp salads all spring long.
2. Spinach
Spinach loves the cooler temperatures of early spring. In a hydroponic system, it grows clean, tender, and nutrient-packed. Harvest the outer leaves often to keep it producing steadily.
3. Kale
Hardy and versatile, kale is one of the easiest vegetables to grow in a hydroponic tower. Young leaves are tender for salads, while mature leaves are perfect for smoothies or sautés.
4. Rocket (Arugula)
If you love bold flavour, rocket is a must-have in your hydroponic garden. It grows rapidly in vertical systems and can be ready for harvest in as little as 4–5 weeks.
5. Silverbeet (Swiss Chard)
Silverbeet not only grows well in a hydroponic system, but its colourful stems also make your tower look vibrant. It’s a hardy, reliable crop that provides endless leafy greens.
6. Basil
Spring is prime basil-growing season. In your hydroponic tower, basil will flourish in the warmer weather, giving you plenty of leaves for pesto, salads, and fresh garnishes.
7. Parsley
Both curly and flat-leaf parsley thrive in hydroponic gardens. Easy to grow and full of flavour, it’s a herb you’ll keep harvesting again and again.
8. Bok Choi/Pak Choi
Bok Choi and Pak Choi is perfect for spring planting in a hydroponic system. Enjoy the leaves in a stir-fry, stew or soup.
9. Spring Onions
Compact, fast-growing, and ideal for small spaces, spring onions thrive in hydroponic towers. They’re easy to tuck between leafy crops and provide a mild, fresh flavour.
10. Strawberries
Not a vegetable, but one of our favourite things to grow in a hydroponic garden for juicy, sweet goodness. Eat on their own, in a breakfast bowl, dipped in chocolate on Christmas day, or in a smoothie. We love Strawberries!
