How to Plant Garlic: A Simple Guide for NZ Gardeners
There’s something incredibly satisfying about pulling up your own garlic bulbs after months of growing. Whether you're a beginner or seasoned green thumb, growing garlic in NZ is easier than you think — and winter is the perfect time to get started. This garlic planting guide covers everything you need to know, from choosing the right varieties to harvest and storage tips.
When to Plant Garlic in NZ
The best time to plant garlic in NZ is around the shortest day of the year, typically in June or July. This timing allows garlic bulbs to develop strong roots over winter and form large cloves by summer. You'll then harvest garlic around the longest day, usually in December.
Choosing Garlic Varieties
For best results, look for garlic varieties NZ gardeners trust, such as Printanor (the most widely grown in NZ), Takahue, or Ajo Rojo. These varieties are well suited to our climate and known for good flavour and storage life.
Avoid supermarket garlic — it’s often treated to prevent sprouting. Always buy certified seed garlic for safe and successful results.
Soil Preparation and Planting
Garlic thrives in well-drained, loose soil enriched with compost. Good garlic soil preparation is key — work in a general-purpose fertiliser or a specific garlic fertiliser before planting.
Break bulbs into individual cloves (leave skins on), and plant them pointy end up, around 5 cm deep, and 15 cm apart, in rows spaced 30 cm apart. These garlic spacing tips help ensure airflow and reduce disease risk.
Raised beds or containers also work well, as long as the soil drains freely. Garlic doesn’t like wet feet!
Garlic Care Tips
Water regularly during spring but ease off as bulbs mature and tops begin to yellow. Avoid overwatering, especially in winter.
Weed regularly, as garlic doesn't compete well with weeds. You can also add garlic companion plants like chamomile or lettuce to make the most of your space and keep pests away.
Keep an eye out for garlic pests and diseases, especially rust and white rot. Proper spacing and crop rotation help reduce the risk.
Harvesting, Curing, and Storing Garlic
When the lower leaves start to brown and only a few green leaves remain, it’s time to harvest garlic. Lift bulbs carefully with a fork — don’t pull by the stems.
Lay garlic out in a dry, airy spot for 2–3 weeks to cure. Once dry, trim roots and leaves, and store in a cool, dry place.
Proper curing and storing garlic are essential for extending shelf life and ensuring your homegrown garlic lasts for months.
Final Thoughts
Planting garlic in winter is a fantastic way to grow your own flavoursome, chemical-free crop. With the right prep, spacing, and care, you’ll enjoy big, healthy bulbs just in time for summer.
