Why does your Lilium LA Hybrid Puma have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often experienced by LA Hybrids like 'Puma'. They pierce the lily's leaf cells to feed on sap, leaving behind fine silk webbing as they build colonies.
Specifically in lilies, these mites create dense webbing around the flower buds and leaf junctions. This can lead to premature bud drop and stippling (tiny yellow dots) on the foliage of 'Puma'.
While not a pathogen, extremely dry air can cause delicate lily tissues to contract and create micro-fissures that may trap dust or debris, sometimes mistaken for fine organic webbing.
