Sustainable Cow Pots for Better Garden Plants

Sustainable Cow Pots for Better Garden Plants

The best kind of sustainability is to take a waste product and turn it into a valuable resource; to turn garbage, as it were, into gold. There’s a farm family in northwestern Connecticut doing just that these days, and in the process it’s also creating an opportunity for gardeners.

Amanda Freund is, along with her sister Rachel and brother Isaac, the third generation of her family to work the Freund Family Farm in East Canaan, Connecticut.   Historically it has been a dairy farm and the Freunds still milk some 300 cows.   Keeping that kind of herd creates a potential for serious pollution: the farm’s acreage sits in the watershed of two rivers and its cows deposit some 30,000 lbs. of manure and urine every day.

But, says Amanda. her father Matthew decided to treat the manure piling up in the barn not as a problem but as an opportunity. Twenty years ago he installed a digester that extracts methane from the manure, producing enough gas to heat the family home while also separating the manure’s liquid from its solids. The liquid, as a sort of manure tea, the farm pumps out to use as fertilizer on its 400-500 acres of corn and other crops. The solids Matthew used to process into compost which he sold through his wife’s garden center. But then he found a better use.

Starting with a pot on the kitchen stove, he began experimenting with turning the manure solids into biodegradable growing containers; by 2006 he had a product ready for sale and the machinery he needed to manufacture it in bulk. This container has, in a university test, proved superior to other biodegradable containers such as peat pots in at least one very important respect. Once in the soil, once transplanted into a garden bed, the “cow pots” (as the Freunds call them) break down faster and more completely so that the gardener is less likely to experience what I have always found to be a disadvantage with peat pots, that when I pull plants at the end of the growing season, their roots are still largely confined to the pots in which I originally planted them.

Amanda Freund suspects that it is the nitrogen content of cow pots that enhances their decay. And of course, unlike peat pots, which draw on what many experts maintain is, in practical terms, a non-renewable resource, cow pots are tapping a renewable resource in over-abundant supply. To date, her family has produced some 35 million of these ingenious containers, controlling water pollution on the farm while conserving natural resources.   You’ll find them for sale during the winter-spring seed-starting season at local retailers and on-line as well. Why not do your bit for the environment and give your plants a treat? Give cowpots a try.

    I tried them when they first came out a few years back, and then at least, my response was basically “meh”. I very much liked that they were biodegradable, but other than that, I didn’t notice any appreciable difference in the plant growing in them. They were healthy enough, but not really any more than others. Maybe I’ll try them again – but the first time around wasn’t enough to convince me.

    They are better for the peat bogs, and at least a partial solution of what to do with all of that cow manure. For me, living as I do in the area, they are also a locally sourced product, which is greener.

    I first saw Cowpots mentioned on TV (Dirty Jobs? 20/20? *shrugs*) back when they were a brand-new idea and told my husband I wanted them for Christmas. It took a bit back then to find them here on the West Coast, but he did. Now I get them every year. Haven’t used peat since, but I still find pieces of old peat pots in my compost and garden soil from time to time. Not so the Cowpots.

    I’ve always wondered about these sorts of pots. I mean sure using a waste product as material to make a pot seems great, but you have to get new ones every year. I am still using the commercial grade plastic ones I purchased over a decade ago. I imagine I have saved more in petroleum from a lack of annual shipping and packaging than was used in their manufacture.

    It’s great that you are recycling, but nevertheless the carbon footprint of a plastic pot is huge, given all that is involved in the extraction and processing of petroleum. Turning waste into a resource is a win/win environmentally.
