C)Other cultivated grounds We use chemical control as a last resort. We are careful to evaluate the possible threat that each pest might represent. During the summer, we focus on weeding and pruning around the campus. When possible, we manually remove the pest such as bag worms removal from trees and weeds removal, when possible. We try to use the least caustic form of removal. When planning the landscaped areas, we prioritize pest-resistant cultivars. In addition to that, when we fertilize the grounds, we use cow manure and peat moss instead of other types of fertilizers.
