Healthy soil is at the heart of everything we do at Hart Farm Midvale. Across the property—whether in the orchard, the market garden, or the rolling grassland and wetland spaces—we work to build soil that supports a diverse and resilient landscape. We follow organic principles and return natural materials to the land through composting, vermiculture, and other practices that strengthen soil structure, biology, and long-term fertility. As we improve different areas of the property, we incorporate plant species that fit the local conditions and grow naturally alongside the native vegetation. The sections below describe the methods we use to build and support healthy soil throughout the farm.
We create compost using a balanced mix of carbon-rich and nitrogen-rich materials sourced from our home, our farm, and local businesses. We also supplement with locally sourced OMRI-certified compost when establishing new plantings or expanding growing areas. As our on-farm composting and vermiculture systems continue to develop, our goal is to meet more of our soil-building needs directly on the farm.
We maintain a large vermiculture windrow populated with red wiggler composting worms (Eisenia fetida), a species known for efficiently breaking down organic matter. These worms transform diverse organic inputs into nutrient-rich vermicompost that supports healthy soil biology across the property.
A key part of our process is feeding alternating sides of the windrow. By adding fresh material to one side at a time, we encourage the worms to naturally migrate toward the newest food source. This allows us to harvest finished castings from the opposite side with minimal disturbance to the worms and without mechanical separation.
We brew actively aerated compost teas during the growing season to support microbial diversity and healthy soil biology. These teas rely on our own worm castings and farm-made compost, which supply beneficial organisms that help build living soil structure and support resilient plant growth.
