What's eating my grape-leaved passionflower?

Passiflora vitifolia, grown as a tropical climber, faces spider mites as its most common pest — especially in warm, dry conditions — alongside aphids that colonise new shoots and whitefly on leaf undersides. As a tropical subject often grown under glass, these three sap-suckers dominate the pest picture; neem oil addresses all three.

Pale yellow mottling and stippling across leaves, fine silk webbing beneath; premature leaf drop in severe outbreaks Raise humidity; spray with horticultural oil or insecticidal soap; repeat every 5–7 days; introduce predatory mite Phytoseiulus persimilis under glass

Clusters on soft shoot tips distort and curl new foliage; honeydew leads to sooty mould and can vector virus disease Remove by hand or water jet; apply insecticidal soap or neem oil; use yellow sticky traps to monitor

Clouds of tiny white-winged adults rise when foliage is disturbed; nymphs feed on leaf undersides causing yellowing and honeydew deposits Use yellow sticky traps; spray insecticidal soap or neem oil targeting leaf undersides; introduce Encarsia formosa under glass
