I am looking for a way to recycle the contents of 3 old down-filled cushions. The obvious way is to add them to my compost heaps but I suspect it would be hard to keep the feathers where I want them. My compost heaps are near my neighbour’s back door and patio so it could be messy and inconsiderate. In the next few weeks I will be planting out my tomato plants into the soil in my greenhouse. I usually dig a trench and fill it with composted FYM. This year I thought I might put the feathers in the trench first. How silly is this idea?
