About Leaf Produce in Kerikeri

Leaf Produce brings you fresh, tasty homegrown produce from our home garden in Kerikeri, Bay of Islands, New Zealand, since 2016.

Kerikeri is a growers’ paradise, with beautiful rich, volcanic soil – plus a commercial irrigation scheme (with water coming from irrigation lakes), so our produce has enough water all year round.

We've been selling our herbs, veges, and plants at The Old Packhouse Market, and sometimes at the Kerikeri farmers' market. Now you can buy selected products online, too!

Growing philosophy at Leaf Produce Kerikeri

We grow everything as naturally as we can, as we are passionate about the importance of healthy produce, healthy humans, and a healthy ecosystem. This means that we are continually trialling and experimenting with our growing methods so our plants and produce are as healthy as possible, using natural practices. It's very much a process of continual improvement, and learning to adapt to the different seasons and different weather patterns.

Most of the produce is grown from seed right here at Leaf Produce. But if we haven’t quite mastered on how to grow something from seed (some plants are mighty tricky to germinate), then we buy quality seedlings and grown them on.

Healthy, non-sellable plant matter is composted or used as mulch – we try not to waste anything, and it’s good to recycle the plant nutrients on-site.

We can't produce enough compost for our needs, so we buy in a specially formulated blend from a specialist wholesale supplier, that's free from artificial/chemical fertilisers.

Our approach to spraying

I really wanted to grow spray-free produce when I first started Leaf Produce. But I quickly learned that pests and diseases thrive in the warm, humid environment in our particular microclimate in Kerikeri. And the bugs just LOVE my yummy salads and herbs! I lost numerous crops – and income – so although being completely spray-free is a nice idea, it just isn’t a viable business model in this part of the world.

I do want to avoid the use of chemical sprays though - so I use natural sprays, but only as a last resort.

Our integrated pest management plan involves:

  1. Physical barriers: i.e. netting to keep the bugs away as much as possible. The netting doesn’t stop the bugs completely though – they are VERY determined to eat my yummy produce!
  2. Companion planting: certain plants growing together will help repel some bugs.
  3. Observation: I keep a close eye on all my crops, to check for early signs up bug damage.
  4. Manual control: Sticky traps are great for gnats, and I also spend time as needed squishing problematic bugs, such as caterpillars and slugs.
  5. Selective use of a natural spray: If bugs are found, only those plant beds with issues are sprayed. I use a natural spray, pyrethrum, which is actually a daisy extract, and the same spray that’s used by organic growers. What’s more, I’ve completed the Growsafe training to ensure that I’m using the spray safely. Withholding periods are strictly observed.

Note that our microgreens are spray-free, and in a growing media that's free from artificial fertilisers and chemicals.

Matthias Luethi, mentor

Cornelia’s father, Matthias, had a successful horticultural business in Kent, England, where he supplied 5-star hotel and restaurants in London’s West End with his farm-grown produce, 6 days a week. (The photo shows Matthias Luethi on the front cover of the Sunday Times Magazine in 1990.)

As well as being the first commercial grower of wild rocket in England, he also grew gourmet lettuces (before they became mainstream supermarket items), herbs and baby vegetables.

Matthias helped Cornelia set up Leaf Produce’s growing operations, and provides advice and ideas by phone and email.
