watering

This native North American species of Equisetum is ideal for a wide variety of soil and sun conditions. It prefers damp soil and should be watered once weekly during the summer months, providing enough water to keep the soil damp but not so much that it puddles. During the winter months, the scouringrush horsetail will require less water, so allow the top layer of soil to dry out before watering.

sunlight

Scouringrush horsetail (Equisetum hyemale) is a plant species that prefers full sunlight. For best growth, it should get 6–8 hours of direct sunlight daily. The amount of sunlight will depend on the season and the regional environment. In summer months, scouringrush horsetail should receive a full 8 hours of direct sunlight, while in winter it is typically fine with 6 hours.

pruning

Scouringrush horsetail (Equisetum hyemale) should be pruned in late winter or early spring. Start pruning when the plants are still dormant, before growth emerges in the spring. Remove any shoots that are dead or damaged. Prune off shoots that are growing out of bounds or that are too tall. You can also prune off any that are crowding each other or shading desired plants.
