Field Horsetail thrives in consistently moist soil. Water regularly to keep the soil damp, especially during dry spells. Avoid allowing the soil to completely dry out, as this can stress the plant.

Soggy conditions are generally tolerated, as it naturally grows in wet areas.

Pruning is primarily for containment. Remove any stems that spread beyond desired areas or become overgrown. Cut back dead or damaged stems at the base.

Pruning can be done anytime throughout the growing season to manage its size and spread.

Field Horsetail is easily propagated by division of its rhizomes in early spring or fall. Simply dig up sections of the root system, ensuring each piece has some buds, and replant them in moist soil.

It can also be propagated by spores, though this is less common for gardeners.

Repotting is generally not required for garden-grown Field Horsetail. If grown in a container, it may need repotting every 2-3 years to manage its vigorous root system.

Choose a larger pot and refresh the soil, dividing the rhizomes if desired to control spread.
