Why Bottom Leaves of a Polka‑Dot Plant Turn Yellow and Drop

Normal Leaf Shedding vs. Pest Problem

Kristin's Polka‑Dot plant loses a bottom leaf every few days, but the top growth looks fine.

Expert Explanation

Losing lower leaves is normal for many plants as they mature. However, check closely for tiny sucking pests—mites, scale, mealybugs, or aphids—which can cause premature yellowing. Use a magnifying glass if needed. If pests are found, treat with insecticidal soap or horticultural oil.
