Delph disasters

SADLY, delphiniums have a rather alarming list of problems. Pests include slugs and snails, leaf miner, spider mite and leaf-eating caterpillars. Diseases include black leaf spot, root/crown rots, powdery mildew (particularly on wild species and types with purple/violet flowers) and viruses. Fortunately, most of these are rare or not a major problem, and it’s just slugs, snails and powdery mildew that we have to control.

All parts of a delphinium, but particularly the seeds, are poisonous in large doses.
