Water:
Gulf vervain thrives in environments with regular rainfall and prefers consistent moisture, tolerating brief dryness. It requires moderate watering weekly for optimal hydration. Typically grown outdoors, it may need supplemental irrigation during the growing season to support vigorous flowering.
Fertilize:
The gulf vervain thrives on abundant feeding for health and color. Apply organic water-soluble fertilizer directly to the soil to prevent leaf or flower burn. Feed the gulf vervain twice monthly in spring and summer, with some opting for monthly feeding in fall and winter.
Pruning:
Gulf vervain features vibrant purple flowers and exhibits drought tolerance. Prune in early spring to foster growth, shape the plant, and eliminate dead stems. Post-flowering pruning can prolong blooming, while regular pruning promotes a compact form. Utilize clean, sharp tools for optimal health.
Propagation:
Gulf vervain propagation success involves sowing seeds in a well-draining mix, lightly pressing them into the soil. Keep soil moist but not waterlogged; maintain moderate humidity and warmth. Once seedlings establish, thinning may be needed for optimal growth.
