What's eating my new dawn rose?

New Dawn is a vigorous climbing rose that tolerates a range of conditions, but aphids colonize its prolific new growth every spring. Japanese beetles cause widespread damage across the US in summer. Sawfly larvae appear on lower foliage. Its height makes it accessible to deer, and birds may nest within its dense canes.

Masses of greenfly on soft new shoots throughout spring, causing curling and honeydew that promotes sooty mould Spray affected shoots with insecticidal soap or neem oil; hose off from a ladder where necessary on tall climbers

Skeletonized upper foliage and destroyed blooms from June to August across most of the US Hand-pick in the morning; use neem oil spray across the canopy; apply milky spore or beneficial nematodes to surrounding lawn

Skeletonized patches on lower accessible leaves in late spring; larvae are pale and slimy Inspect and remove larvae by hand; apply pyrethrin spray to lower canes and foliage

Young climbing shoots and lower foliage browsed back, particularly in spring and late autumn Protect the base of canes with wire mesh or deer repellent; tall fencing is most reliable in high-pressure areas
