Reliable source for heritage seeds

This was my third time ordering from Koanga, and they're consistently good. I first got some native NZ plants a couple of years ago, then last year I bought some garlic bulbs and seed potatoes. This time, I picked up some heritage grain seeds and a few different squash seeds. Everything always arrives well-packaged and in good condition. The seeds germinate reliably for me, and I appreciate knowing they're committed to preserving these older varieties. It's why I keep coming back, even if I have to wait a little longer for delivery sometimes, which is understandable for specialty items. The consistency is what really stands out.

Good quality, a bit pricey

I bought a hand-forged trowel and some compost tea bags from Koanga. The trowel is really well-made and feels sturdy, definitely a quality tool that should last. The compost tea bags are convenient too. Shipping was reasonable, took about 4 business days to get to Auckland. My only minor gripe is the pricing; it felt a little on the higher side compared to other gardening suppliers, especially for the tea bags. But for the unique heritage products and ethical sourcing, I guess it's worth it. Overall, a good experience and I'd consider shopping here again for specific items.

Fantastic seeds, super fast shipping

I ordered a bunch of heritage tomato seeds and some heirloom bean seeds last week and they arrived so quickly! I think it was only 3 days to my place in the South Island. The packaging was great, and the seeds look super healthy. I can't wait to get them planted this spring. I'm definitely going to buy more from Koanga, and I've already told my gardening group about them!

Easy to find what I needed

I was looking for some specific medicinal herb seeds and found them easily on the Koanga site. The website was pretty straightforward to navigate. Shipping took about a week, which was fine. The seeds look decent, and I'm hopeful they'll grow well. It was a pretty chill shopping experience overall, no fuss. I might check out their gardening books next time if I need more info.
