Why does your Hosta fortunei have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are common pests for Hosta species, especially in hot, dry conditions. They pierce the leaf cells to feed, creating fine silk webbing and causing stippling (tiny yellow dots) on the foliage.
In advanced stages, a heavy population of mites creates dense, visible webs that can cover entire leaf clusters, eventually leading to bronzing and death of the Hosta foliage.
While less common than mites in Hostas, some scale species produce a waxy, cottony substance that can be mistaken for fine webbing or silk.
