Reviving a 30-Year-Old Gardenia Ravaged by Aphids

Two-Pronged Attack

A massive, 30-year-old gardenia in NC was hit hard by aphids last year. It's leafing out with buds but looks weak.

Immediate Care

• Spray for aphids now with horticultural oil or insecticidal soap—cover undersides thoroughly.
• Apply a granular, acid-forming fertilizer (like Miracid) around the dripline.
• Water deeply once a week.
• Mulch with pine straw or bark.

Pruning Advice

After flowering, prune lightly to shape and remove dead wood. Avoid heavy pruning on old plants. For detailed care, consult the Clemson University fact sheet HGIC 1065.
