What's eating my maranta 'lemon lime'?

Maranta 'Lemon Lime' is most bothered by spider mites, which attack the thin, moisture-loving leaves when indoor air is too dry. Mealybugs and fungus gnats round out the typical pest list. The prayer plant's habit of folding leaves at night makes it easy to miss pests hiding in the folds.

Fine webbing and pale speckling on the underside of the chartreuse-and-green leaves; leaves may curl and drop. Increase ambient humidity, shower the plant to dislodge mites, and apply neem oil spray every 5–7 days for three to four weeks.

White woolly masses tucked into the leaf folds and along the petioles; honeydew causes sooty mould. Dab with isopropyl alcohol on a cotton swab; repeat every few days and follow up with insecticidal soap spray.

Larvae in consistently moist potting mix nibble fine roots, causing wilting despite adequate watering. Allow the top inch of soil to dry before each watering; apply a Bti drench to kill larvae in the soil.
