Why does your Lilium Oriental White Proud have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
This is the most common cause of fine webbing on Oriental Lilies, especially in hot, dry conditions. These tiny arachnids pierce the plant cells to suck out sap, leaving behind fine silken webs around the leaf undersides and stems.
While not producing true webs, cells that burst due to uneven water uptake can create a crusty residue or small bumps that may look like debris or fine filaments under high humidity. This is common in Oriental Lilies when soil moisture fluctuates rapidly.
Though they don't spin webs, heavy thrips populations can cause silvery scarring and irregular patterns that might be confused with webbing at a distance. They feed on the tender tissues of developing lily buds and leaves.
