Plant Care
Black Hollyhocks are relatively low-maintenance plants that thrive with basic care. Water deeply but infrequently to encourage deep root growth, and avoid overhead watering to prevent fungal diseases. Remove spent blooms to promote continued flowering and prevent self-seeding. Support may be needed for tall stems, especially in windy areas. Apply a layer of mulch to retain moisture and suppress weeds.
Planting Instructions
Plant in spring or fall when temperatures are mild. Dig a hole twice the width of the root ball and at the same depth. Place the plant in the hole, ensuring the crown is level with the soil surface. Backfill with soil, firm gently, and water thoroughly. Space plants 18-24 inches apart to allow for proper air circulation. Add a 2-inch layer of mulch around the base, keeping it away from the stem.
