EVERGROW ORCHARD
Updated: Feb 26, 2020
Hard Grafter
Horticulturist and fan of the natural sciences, when Evergrow Orchard’s Sheryl Black isn’t grafting varieties to make a better cherry she’s trialling avocado growing in North Otago. Joseph Banks, eat your heart out.

Five minutes outside Oamaru, snuggled in the bosom of the rolling hills is a cherry orchard where innovation and experimentation meet good old fashioned green fingers. A pocket handkerchief sized piece of land, on an acre 1200 trees produce over a tonne of fruit inside plastic-covered tunnels that look like transparent caterpillars - and that’s with half the orchard only starting to fruit this year. Cherry trees can be Methuselahs, living for up to 80 years but their longevity does not mean they are easy to love - in fact cherries are one of the hardest things to grow. “You can’t just plant one and hope for cherries in Summer: you have to keep the rain off or they'll split, you need to keep the black aphids and the birds off them … you have to be dedicated to this tree,” says Sheryl.
For the last four years Sheryl and Warren Black’s cherries have been sold on Wansbeck Street over the summer, having bought the trees off Fred and Jill Field of Oamaru and moved them here. The cherry varieties are Stella and Lapin - French for rabbit. “And maybe they are named that because they are really big bunnies.” They also grow Tart (sour) cherries, plums and other stone fruit.
Oamaru is a great place to grow cherries. They ripen slower here than in central Otago, 120 days to ripen from blossom to picking versus 70 in Central Otago. The result is that they have a better cell structure and last longer once picked.
The ultimate grow-hards, today Sheryl and sister in law Suzanne are busy pruning, “dealing with pockets of chaos that happened over Christmas but we were too busy to deal with.” The Black family business is divided along the sexes in an interesting way: the husbands are away working as loggers, while the women are propagators. Planters married to choppers.
In the grow tunnels the trees have boughs like short bumpy arms with fat fruit fingers. They aren’t planted normally in the ground, but inside special bags made on site called EverGrow Bags, and this is the secret of their success. Filled with local soil, the bags cause a ‘bonsai’ effect: sat above ground they cause ‘air pruning’, where the root embeds in the soft inner fabric instead of circling until rootbound as in smooth walled pots. It then senses the air and thinks “nope’ before branching out back along its length. If the bag is planted in the ground, as most of the orchard is, the roots grow through the rot proof fabric into the surrounding soil, but as they thicken they get squeezed and this also causes them to laterally branch within the bag. This stops the tree being too vigorous and “because they are not having to be a huge tree, as soon as they realise they don’t have to put all their energy into that they focus on fruiting,” explains Sheryl. You do have to prune them but not nearly as much as you would if their roots were given a free reign in the ground.
"We make EverGrow Bags right here and they are becoming popular with people who want to have a patio or backyard orchard, keep the trees small and easy-care, and even dig them up bag-and-all and take them with them if they shift house."
This really should end with a joke about cherries, but they’re all pit-iful.

What a fantastic profile — Sheryl Black sounds like exactly the kind of grower who keeps horticulture interesting. I was especially taken with the detail about the EverGrow Bags and the "bonsai effect." The idea that air pruning tricks the root into thinking "nope" and branching back along its length is such an elegant solution to the rootbound problem, and it explains how 1200 trees can thrive on a single acre. The description of the tunnels looking like "transparent caterpillars" with trees bearing "fat fruit fingers" really brought the place to life.
The ripening comparison fascinated me too — 120 days from blossom to picking versus 70 in Central Otago, and the payoff being better cell structure and longer shelf…
This piece had me smiling all the way through, especially the image of the tunnels like “transparent caterpillars” and the line that the husbands are away as loggers while the women are the propagators — “Planters married to choppers” is exactly the kind of dry, practical wit you hear in real orchards. Sheryl’s warning that cherries are one of the hardest things to love rings true: keeping rain off so the fruit doesn’t split, fighting black aphids and birds, pruning after the Christmas rush when “pockets of chaos” have set in — that’s not gardening, that’s devotion with a secateur. I was also fascinated by the regional detail that Oamaru fruit ripens in about 120 days versus roughly 70 in…
What a fascinating look at Evergrow Orchard’s innovative cherry growing and avocado trials—Sheryl’s blend of science and hands-on skill is truly inspiring. For anyone who loves exploring stories like this through photos and discussion, you might enjoy the image chat community too.
The care behind these cherries really comes through, especially the balance of grafting, tunnel growing, and root management in the EverGrow Bags. It would be lovely to create a visual keepsake of work like this with a tool that can create a drawing from your photo.
This is such a lovely look into Sheryl and Warren's world - the fact that they literally picked up the trees and moved them is dedication I can't even imagine. The bit about cherries being one of the hardest things to grow really hit home though; so many people think you just plant and wait, but the rain protection alone sounds like a full-time job. Speaking of capturing all that hard work, I've been meaning to pull some stills from my own garden time-lapses to track how my trees are developing, and this video to frame tool has been surprisingly handy for that - just grab a frame each week and compare. Makes you appreciate the patience folks like the…
