Burning Bush Trouble? Check for Insects, Not Fertilizer pH

Why "Acid-Loving" Fertilizer Isn't the Problem

Burning bushes (Euonymus alatus) tolerate a wide soil pH range, so a water-soluble fertilizer for acid-loving plants won't hurt them. The real issue? That sticky residue you mentioned is a classic sign of sap-sucking insects — likely aphids or scale.

How to Confirm an Insect Infestation

• Check leaf undersides for tiny, soft-bodied insects (aphids) or immobile bumps (scale).
• Look for black, sooty mold on leaves — it grows on insect honeydew and rubs off easily.
• Sticky leaves + black mold + visible bugs = active infestation.

Treatment Is Simple and Effective

Both aphids and scale are highly treatable:

• Spray horticultural oil or insecticidal soap for direct contact kill.
• Apply a systemic like imidacloprid (Bayer Advanced) as a soil drench for season-long control.
• Repeat as needed per label instructions.

Don't Blame the Fertilizer

The "Super Grow" didn't cause the decline — it just coincided with an insect outbreak. Treat the bugs, and your burning bushes will bounce back.
