Mites are tiny, eight-legged arachnids that feed on the sap from the leaves, causing them to become discolored and distorted.
Slugs are slimy, soft-bodied creatures that feed on the leaves and petals of dahlias, leaving behind silvery trails.
Finally, caterpillars are the larvae of moths and butterflies and can cause significant damage to dahlia plants by feeding on the leaves and stems.
Preventative Steps to Protect Dahlias
Protecting dahlias from pests is essential for having a healthy and vibrant garden.
