If you make your own potting mix or seed - starting dirt engine block , your formula probably postulate at least some peat moss . In fact , myriad gardening books and magazines still praise peat for its ability to retain wet and improve soil grain . The ingredient certainly has its benefit , but we ’d all be well served by get out more of this rude imagination undisturbed .
“ If we were n’t in the state that we are with our clime , I think [ using peat ] would n’t be quite such a negative affair , ” says Briana Bosch , owner of Colorado - basedBlossom & Branch Farm . “ But , because of the dire straits that we ’re in with climate change and C emissions , we really ca n’t afford to be taking away such a massive sequester - er of atomic number 6 . ”
Bosch tally , “ When [ peat ] is harvested , it actuallyreleasesthat carbon , so then it becomes a contributor . ”
Going Peat-Free
With that in mind , Bosch start combing her local gardening shopping centre for peat - gratis alternatives last fall . interpret the fine photographic print on product web site and promotional material was somewhat dishearten . “ There ’s really not a lot on the U.S. market place that ’s peat - free , ” she says . “ Part of that is because so many people do n’t know to ask [ for peat - costless intersection ] . ”
Bosch was capable to detect some peat - free option . She feel a product calledBeyondPeatat Wal - Mart , for instance . And she discoveredFoxFarm ’s Coco Locopotting mix , brick of compressed coconut coir fiber andgreen sand .
“ We just kind of grabbed a bunch of stuff off the shelves , ” Bosch says . “ And I tell , ‘ I ’m going to try commingle all of these things at dissimilar ratios and see if I can get a soil - block formula that I ’m happy with . ’ ”
After hatful of trial run - and - mistake , she did . ( She deal her peat - free , grunge - blocking formula and pointers inthis picture . ) “ We ’ve had really good results with that , ” she pronounce . “ But , of course , now we ’re always trying to take the next footstep forward for sustainability . I started looking at the coconut coir , which has its own set of issues . ”

Coconut Coir Caveat
What ’s the problem with coconut coir ? For starters , processing it is very water - intensive . “ In its lifelike state , coconut coir tends to be really mellow in saline , ” Bosch enjoin . “ Obviously , that ’s not proficient in horticulture . So , it study a heap of water to sue it to the point where we can utilize it .
“ And water is a wanted rude imagination , too . ”
Also , Colorado is n’t precisely teeming with coco palm orchard . So , the resource travels a tenacious way to get to Bosch ’s farm . As such , she began a new search for horticulture factor with an even smaller atomic number 6 footmark .
To engagement , Bosch has yet to recover a potting soil mix that contains neither peat moss nor coconut tree coir . She has experiment with Timothy Miles Bindon Rice hulls , foliage mulch and folio moulding as possible substitutes . Bosch lately modify her stain - blocking formula again . It now includesPittMoss , a blend of recycle cellulose fiber , as a main constituent . With the newfangled summation , she ’s been able to reduce the amount of coconut coir she uses .
“ That was really intriguing , because it is material that was otherwise going to go to the landfill , ” Bosch remark . “ It ’s OMRI - certified , so there ’s nothing weird in there . It ’s cellulose , and , so , its pee retentivity is really good .
“ We tweaked the [ soil - block ] recipe a minuscule bit to make it exercise . ”

Good, Better, Best
So far , the new concoction is working . However , finding a hyper - local imagination that works just as well would be even more ideal . “ mistreat one is to mistreat off from peat moss and encounter something else , ” Bosch says . “ And then the next , even beneficial step is just finding something recyclable like the PittMoss . And then the good affair is to ascertain something that is in your own yard . Or something that you ’re reusing from the [ local ] environment . ”
Of of course , fulfill all that on a large scale does n’t easy happen overnight . “ Especially with boastful military operation , ” Bosch says . “ If someone is scared to do a heavy transfer , say , ‘ OK . Next season we ’re go to try starting a quarter of our seed in something that ’s peat - free . ’ Then tweak it if you need to .
“ And then in the [ pursual ] class you’re able to inflate . One stride at a meter . ”
