Wood horsetail thrives in consistently moist, slightly acidic soil and prefers dappled shade or partial sun, making it ideal for bog gardens or shaded borders. It is a fast-growing, ancient plant that spreads via rhizomes and can become vigorous in optimal conditions, so use root barriers if space is limited. Avoid letting the soil dry out, and site it away from delicate plants it may outcompete.
