Care:
Prune off the flower stalks after the plants are done blooming in late summer or early fall.

Because larkspur plants are highly susceptible to diseases, cleanliness in the garden is crucial for them, so do not let the old vegetation lie around all winter.

To lessen the likelihood of your plants being infected by such disease, provide adequate spacing, mulch your larkspurs, and keep your garden free of debri
