Horticultural Oil and Sulphur Treatment

Horticultural oil and sulphur treatment is a practical choice for protecting fruit trees, shrubs, and ornamental plants from common overwintering pests and certain fungal diseases. Applied as a dormant treatment in early spring before bud break, horticultural oil helps control insect eggs, larvae, and overwintering pests, while sulphur products can help manage certain fungal problems. These garden treatments are well suited to home orchards, edible gardens, ornamental landscapes, and other outdoor growing areas where preventative protection is needed at the beginning of the season. For gardeners in Quebec and across Canada, dormant oil and sulphur treatments offer a convenient way to support healthier plants before pest and disease pressure increases. Our collection brings together horticultural oil, sulphur treatments, and related products for fruit trees, shrubs, and ornamental plants, making it easier to find the right option for your spring garden needs.
