Answer: Dahlias are heavy feeders so if you haven't fed them recently, try side dressing with a slow release 5-10-10 or use a foliar fertilizer such as Miracle Gro. Aphids, Red Spidermites, Leafhoppers, Japanese Beetles, Thrips, and Corn Borers are the most common dahlia pests. You can control these with products such as Safer's BioNeem or Power Force Multi-Insect Killer by Bayer. Enjoy your dahlias!
