Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter.
Tuberous vervain prefers well-drained soil and can tolerate some drought once established.
Deadhead spent flowers regularly to encourage continuous blooming throughout the summer and fall. Cut back plants in late autumn or early spring to remove dead or damaged growth and to shape the plant.
This promotes vigorous new growth.
Propagate by division of tubers in early spring before new growth begins. Stem cuttings can also be taken in summer and rooted in well-draining potting mix.
Seeds can be sown in spring, though they may not come true to type.
Repot established plants every 2-3 years in early spring to refresh the soil and provide more space. Use a well-draining potting mix, such as a cactus or succulent blend. Ensure the new pot has adequate drainage holes.
