Shredded harts tongue ferns
The RHS suggest that these plants are generally pest-free but mine have clearly been attacked by something. Many of the leaves are shredded right back to the central spine and others are full of holes. This is the first time I have grown them and would appreciate some advice: is it likely to be slug or caterpillar damage? Should I remove the damaged leaves? Should I have sprayed them?
Thank you for your comments: photo attached:
OMG..never seen one like that ..chewed right down to the bare mid rib.
Never known anything to damage them before like that.
