This state-of-the-art fertigation system was an funding for Sauk Farm, a 20-acre natural tree fruit farm in Washington’s Skagit Valley, however grower Griffin Berger says it’s a essential a part of his strategy to “construct resiliency within the bushes.” (TJ Mullinax/Good Fruit Grower)
No recipe exists for regenerative natural apple rising within the western foothills of Washington’s Cascade Vary, a world away —climate-wise — from the apple trade’s epicenter east of these mountains.
“We don’t have the luxurious of 5 generations of information,” mentioned Griffin Berger, who co-owns Sauk Farm along with his father, Jesse. They’ve grown a pastime farm right into a soon-to-be 20-acre natural orchard enterprise over the previous seven years, because of Griffin’s power for experiments.
“I’m nonetheless studying,” he mentioned. “It’s a continuing journey of studying.”
Cowl cropping. Composting. Making compost tea blends. Fertigation.
Berger credit his “vitamin first” and soil-health-heavy strategy with enhancing his bushes’ resilience and enhancing the flavour of the fruit.
To stop high-density apple orchards from functioning like a monoculture, Sauk Farm embraces cowl crops, which they rotate from a nitrogen-fixing clover combine, seen right here, to a disease-suppressing mustard combine, together with compost and manure, to construct a various soil microbiome.

“I’m solely in enterprise as a result of I can produce taste,” which is what drives shoppers to spend extra for regionally grown natural apples, he mentioned. “I don’t have a enterprise with out that.”
His enterprise produces fresh-market apples and processed Honeycrisp merchandise which might be bought in about 100 shops. A few third of his merchandise are bought by the Puget Sound Meals Hub Cooperative, which was based in 2016 to construct a provide chain for Puget Sound farmers to entry retail and wholesale markets. Berger serves on the cooperative’s board of administrators.
“For being the younger man that he’s, he’s a robust chief and brings actually modern, progressive concepts whereas additionally staunchly representing a preservationist strategy to the co-op’s mission that we’re serving native farmers, serving to them to develop their gross sales channels,” mentioned government director Andrew Yokom.
He highlighted Berger’s innovation and embrace of expertise.
“What I see Griffin doing along with his adoption of expertise in his orchard and processing rooms is discovering methods to compete on value and high quality,” Yokom mentioned. “You may develop fruit so much cheaper out in Japanese Washington, due to this fact, it’s as much as us to supply worth to our clients. They’ll see it within the high quality of his contemporary apples and processed merchandise.”
On the farm, these progressive concepts embody planting high-density orchards with concrete posts from Italy, investing in a platform and state-of-the-art fertigation programs, and a brand new system for brewing compost tea.

Although he studied at Washington State College, Berger mentioned he usually has to look farther afield, at analysis from Midwestern or European climates, to get concepts that apply to his orchard. Past that, he conducts his personal experiments. Good Fruit Grower visited with him to be taught extra from his unconventional strategy to orchard soils.
“We’re simply attempting to construct resiliency within the bushes and within the soil to allow them to take care of each given situation,” he mentioned. “The issue with how I farm is that I by no means say no to attempting a brand new factor.”
Take his latest foray into compost tea. His thought was to take soil samples from thriving bushes in consultant soils and encourage microbes within the soil to breed in a substrate of compost and worm castings, fed by molasses, oat flour and kelp powder, amongst different issues. He applies the ensuing microbe-boosting answer to the orchards.
“It took me a 12 months to dial within the microbes we need to feed to the foundation zone of the bushes,” Berger mentioned. Now, he applies it at 30 gallons per acre and has observed extra mycorrhizae within the soils and better nutrient ranges within the bushes, permitting him to skip some foliar nutrient sprays.
Berger additionally designs his fertigation plans to “spoon-feed” each the bushes and the soil microorganisms. His system consists of three Dosatron injectors, so he can apply acidic, fundamental and impartial options concurrently.
He sees the soil system as a method to encourage the variety that results in an environment friendly orchard system.

“An orchard is a monoculture, and we’re attempting to make it not a monoculture,” Berger mentioned. “So, now we have to embrace cowl cropping and manure to get that microbial development and layers of biomass.”
He planted numerous cowl crops, too, rotating two blends each few years. For fumigation and pest and illness suppression, he opts for a sizzling mustard and rapeseed mix, whereas a clover combine with tillage radish and orchard grass boosts nitrogen fixation.
The quilt crops, manure and compost, and fine-tuned fertigation all assist his bushes make extra environment friendly use of their water and nutrient inputs, Berger mentioned.
“I feel with the regenerative factor, it’s attempting to piece collectively what’s lacking with natural certification now,” he mentioned. “Most individuals farm organically by switching out their inputs; regenerative is site-specific and about placing power into dialing in your soils.”
However whereas he chases soil range, he’s pulling again on crop range. Final 12 months, Berger ripped out 3 acres of grapes, and this spring he’ll start planting the first7 acres of a deliberate 15 new acres of MAIA-1, marketed as EverCrisp, and Crimson Crisp apples.
Apples return extra income and simplify his administration and gear wants.
“For the long run, it’s about doing what we’re good at,” he mentioned.
Berger likes CrimsonCrisp for its illness resistance and even cropping, and he mentioned EverCrisp is proving to be very resilient to local weather extremes.
In wet Skagit County, wooden posts pose a rot drawback, so Berger embraced the concrete strategy extra frequent in Europe. There’s a studying curve to utilizing them, with heavy gear wanted to vibrate the posts into place, however the trellis system is then rapidly put in, he mentioned. (TJ Mullinax/Good Fruit Grower)
Sauk Farm began its value-added line to make use of its culls, however the market demand has been so sturdy that it’s now sending most of its Honeycrisp into these merchandise and specializing in different varieties for the contemporary market. (TJ Mullinax/Good Fruit Grower)
To arrange for these new plantings — with 10-foot rows and 2-foot tree spacings — Sauk Farm put in concrete trellis posts final 12 months. Even with transport prices from Italy, the posts make financial sense for his farm, Berger mentioned.
“It’s a very excessive rainfall setting over right here, and the wooden posts simply rot out,” he mentioned, citing a deer fence put in in 2012 that’s already rotting in locations. The permanence of concrete makes it a sustainable asset. And as soon as the posts are in place, “it simply takes a wrench to construct the trellis system” utilizing galvanized wire clips.
Till these new plantings come into manufacturing, Honeycrisp is his prime crop. However, with the success of the farm’s funding in processing the consumer-favorite apple into juice, applesauce and dried fruit slices, Berger is shifting his strategy to it.
“Plenty of occasions we’re placing completely good fruit into the value-added line,” he mentioned, due to the demand to have stock year-round. Now, he limits his Honeycrisp to 2 picks: Good fruit for the contemporary market, after which every part else for processing.
The strategy permits for labor efficiencies, whilst he shifts to easier-to-grow apples for the contemporary market.
“It’s been quite a lot of trial and error, and I feel that’s what all good farmers ought to do,” he mentioned. “We’re not good, we’re not carried out, however now we have proof of idea and we’re worthwhile.”
