Depends on how you define it
I am frequently asked if I am an organic gardener, based on my reputation for having been heavily involved in composting and compost utilization research since 1972. My answer is yes and no.
The importance of organic matter in soils and the use of compost to improve and maintain soil productivity is not thoroughly appreciated. In my gardening practices, I use a combination of compost and chemical fertilizers and minimize restricted-use pesticides as much as I can.
