Care

Watering

Marsh horsetail requires constantly moist to wet soil. Keep the substrate saturated with water, never allowing it to dry between waterings. In pots, place the pot in a permanent water saucer. This plant thrives at the edge of ponds or marshy areas.

Light exposure

Choose a location in full sun to partial shade. Marsh horsetail tolerates partial shading well but develops better structure with at least 4 to 6 hours of direct sunlight daily. It accepts poorly lit areas but remains less vigorous.

Soil

Rich organic, peaty or silty soil is ideal. Marsh horsetail even thrives in poor soils, but prefers slightly acidic to neutral, humus-rich substrate. Avoid compact, chalky soils.

Pruning and control

This plant doesn't require proper pruning. Simply cut back dried stems in late autumn or early spring. Warning: marsh horsetail spreads via underground rhizomes; contain it in a pot or limit the space if growing it in the ground to prevent invasive spread.

Fertilizer

Marsh horsetail generally doesn't need supplemental nutrients in natural or rich marshy environments. In pots, apply a moderate balanced fertilizer in spring. Avoid excess feeding that would encourage disproportionate growth.

Diseases and pests

Marsh horsetail is very robust and rarely affected by common diseases. Prolonged drying causes it to deteriorate quickly. No major pests affect this species under normal conditions. An overly dry environment remains its main enemy.

Did you know?

Marsh horsetail is one of the oldest plants on Earth: its ancestors dominated the coal forests of the Carboniferous period 300 million years ago, reaching tree-like sizes! Today, this primitive fern accumulates silica in its stems, making them rough and abrasive—once used to polish metals and glass before sandpaper was invented.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
