Usually when people enter the Rose Garden they take a deep breath in through the nose and heave a big blissed-out sigh of appreciation …
Not today. The roses are still blooming; they are still sweetly fragrant, but the smell of the compost we started to spread yesterday is a little overwhelming. We decided to use Bristol’s own compost made from yard waste and … biosolids. If you’re not already familiar with the term, biosolids are the byproduct of sewage treatment. It’s nutrient rich and once it’s been thoroughly composted, pathogen-free. And pretty stinky.
Earlier this week, Gail and I visited the Bristol compost facility – which helped to facilitate deciding between spending the moon on our favorite organic compost that has to be trucked from all the way across the state, and getting Blithewold’s truck filled with the free compost made less than 2 miles away from here. We have both used the rich, dark biosolids compost in our own gardens (because it’s free!) but had never gotten the full scoop, so to speak.
It’s Class A, top grade compost made in a 20 year old facility (soon to be solar powered!) and is free to home gardeners who are able to pick it up themselves and sold to landscapers and garden centers all over the state. Sludge is trucked in from the sewage treatment plant, mixed with finely chopped yard waste, cooked for a minimum of 28 days and aerated by the most enormous rototiller on the planet (says me.) It’s tested for pathogens (fecal coliform) periodically throughout the cycle and the content is fully analyzed for heavy metal levels. Each batch must be within allowable limits – and 100% pathogen-free – before being released from the process. The people who make it are very proud of their product and seem to have good reason to be – plants love it.
We have been talking about amending the soil in the Rose Garden for years now. The soil is probably better than average, evident by the size and health of some of the plants in the garden, but has become more and more compacted and cement-like as we’ve all trampled it over the years. Some roses have struggled to thrive and it’s getting harder and harder, especially in a dry season, to water the garden well. I love thinking that this fall’s rain will really soak in right now rather than run off. And the unpleasant odor, which should dissipate within a few days, to me is a harbinger of next season’s sublime fragrance of a garden full of healthy plants. (Healthy soil = healthy plants.) We’ve taken so much – pleasure, plants and soil – from that garden over the years, it feels really good to finally give something back.
Have you given anything back to your garden yet? (Fall is the perfect time…) Have you ever tried compost made with biosolids? What do you think of it?
