Henry's honeysuckle problems — and how to fix them
Henry's honeysuckle (Lonicera henryi) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Honeysuckle aphids
Colonies of aphids on new shoot tips cause leaf distortion and honeydew deposits. Blast off with a strong water jet or apply insecticidal soap. Encouraging natural predators is the most sustainable long-term approach.
Powdery mildew
Can appear in dry summers, especially in sheltered or crowded positions. Improve air circulation by thinning congested stems after flowering. Keep the root zone moist with mulch, and treat with a sulphur-based spray if needed.
Thrips
Thrips cause silver streaking and flecking on the glossy leaves. Most common in warm, dry conditions. Maintain adequate irrigation and control with insecticidal soap or biological control agents (Amblyseius cucumeris) in glasshouse settings.
