We also harvest water from storeroom and workshop roofs in the area.” When probed about the use of fertigation, (injecting liquid fertil- izer through the drip lines), Bolly admitted the farm was not yet utilizing this practice, and planned to add it to the cultural plant care regime in the future when resources become more available. Jamaica lacks the same access to commercially manufactured amendments, supplements, liquid fertilizers, and other plant prod- ucts that North American farmers and growers take for granted. Bolly therefore relies on a potent, in-house compost blend that the team has perfected over the years. All kitchen scraps (including animal waste) are thrown into large open wooden crates bound by threaded mesh. A collection of carbon-rich materials like leaves, sticks, coconut husks, and scraps from tree pruning are added to the nitrogen-rich kitchen scraps with the addition of effective microorganisms. The team aims for a 5:1 carbon-to-nitrogen mate- rial ratio for optimal decomposition. A tarp covers the crates, which are routinely turned throughout the week. “Every year it gets a little better. A little richer. More fertile,” says Bolly. The farm also forgoes the use of most pesticides, resorting to only natural botanical-based remedies like neem oil or capsaicin. Bolly methodically intercrops the beneficial pest preventative marigold within many of the raised beds as a form of pest manage- ment. The callaloo is planted as to bolt and become shady in time for when spinach and chard need extra protection from the sun. Basil is found growing with tomatoes to improve flavors of both crops and to allow shade for the basil. Scallion (green onion) are found scattered amongst several crops to benefit from the strong allium scent which commonly deters some pests in the garden. Some insect pressure is inevitable in this system of farming, but the crops did not seem to mind the odd pest here or there. Since the farm’s inception, one of the primary goals is to utilize the crops in the restaurant’s supply chain to minimize unnecessary travel costs associated with buying certain crops out of town or out of parish. The restaurants are able to rely on the fact they will never have to source certain crops, and effectively utilize other on and off crops in a tastefully inspired, always changing menu. The hotel also offers a juice bar to other travelers along with its guests, which uses more than 50 per cent farm fresh greens grown on site. Roughly between 15 to 30 per cent of the Rockhouse’s two restau- rants food supply is derived directly from the farm. The hotel effec- tively manages and maintains the crops at a significantly reduced labor cost compared to cost of overhead food expenses, while furthering the autonomy of the organization as a whole. 134 groundbreakers
