Should you make your individual potting combine or seed-starting soil blocks, your recipe in all probability requires not less than some peat moss. The truth is, myriad gardening books and magazines nonetheless reward peat for its capability to retain moisture and enhance soil texture. The ingredient actually has its advantages, however we’d all be higher served by leaving extra of this pure useful resource undisturbed.
“If we weren’t within the state that we’re with our local weather, I feel [using peat] wouldn’t be fairly such a damaging factor,” says Briana Bosch, proprietor of Colorado-based Blossom & Department Farm. “However, due to the dire straits that we’re in with local weather change and carbon emissions, we actually can’t afford to be taking away such a large sequester-er of carbon.”
Bosch provides, “When [peat] is harvested, it really releases that carbon, so then it turns into a contributor.”
With that in thoughts, Bosch started combing her native gardening facilities for peat-free options final fall. Studying the high-quality print on product web sites and packaging was considerably disheartening. “There’s actually not loads on the U.S. market that’s peat-free,” she says. “A part of that’s as a result of so many individuals don’t know to ask [for peat-free products].”
Bosch was capable of finding some peat-free choices. She discovered a product referred to as BeyondPeat at Wal-Mart, as an illustration. And she or he found FoxFarm’s Coco Loco potting combine, bricks of compressed coconut coir fiber and inexperienced sand.
“We simply form of grabbed a bunch of stuff off the cabinets,” Bosch says. “And I stated, ‘I’m going to attempt combining all of these items at totally different ratios and see if I can get a soil-blocking recipe that I’m proud of.’”
After a number of trial-and-error, she did. (She shares her peat-free, soil-blocking recipe and pointers in this video.) “We’ve had actually good outcomes with that,” she says. “However, after all, now we’re at all times making an attempt to take the following step ahead for sustainability. I began wanting on the coconut coir, which has its personal set of points.”

Coconut Coir Caveat
What’s the issue with coconut coir? For starters, processing it is extremely water-intensive. “In its pure state, coconut coir tends to be actually excessive in saline,” Bosch says. “Clearly, that’s not good in gardening. So, it takes lots of water to course of it to the purpose the place we will use it.
“And water is a treasured pure useful resource, too.”
Additionally, Colorado isn’t precisely teeming with coconut groves. So, the useful resource travels an extended approach to get to Bosch’s farm. As such, she started a brand new seek for gardening components with a fair smaller carbon footprint.
“Yearly we get increasingly in depth with the sustainability piece of all this,” Bosch explains. “It’s our duty as growers to be cautious and conscious, as a result of we do depend on the planet to make our residing. A part of that’s being accountable and taking good care of [the planet] in return.”
So far, Bosch has but to discover a potting soil combine that comprises neither peat moss nor coconut coir. She has experimented with rice hulls, leaf mulch and leaf mould as potential substitutes. Bosch not too long ago modified her soil-blocking recipe once more. It now contains PittMoss, a mix of recycled cellulose fiber, as a predominant ingredient. With the brand new addition, she’s been in a position to cut back the quantity of coconut coir she makes use of.
“That was actually intriguing, as a result of it’s materials that was in any other case going to go to the landfill,” Bosch notes. “It’s OMRI-certified, so there’s nothing bizarre in there. It’s cellulose, and, so, its water retention is admittedly good.
“We tweaked the [soil-blocking] recipe a little bit bit to make it work.”

Good, Higher, Finest
Thus far, the brand new concoction is working. Nonetheless, discovering a hyper-local useful resource that works simply as effectively could be much more superb. “The first step is to step away from peat moss and discover one thing else,” Bosch says. “After which the following, even higher step is simply discovering one thing recyclable just like the PittMoss. After which the most effective factor is to search out one thing that’s in your individual yard. Or one thing that you just’re reusing from the [local] atmosphere.”
After all, engaging in all that on a big scale doesn’t simply occur in a single day. “Particularly with massive operations,” Bosch says. “If somebody is scared to do a giant switch, say, ‘OK. Subsequent season we’re going to attempt beginning 1 / 4 of our seeds in one thing that’s peat-free.’ Then tweak it if it’s essential.
“After which within the [following] yr you may broaden. One step at a time.”
