Troubleshooting
Artillery Plant problems — and how to fix them
Artillery Plant (Pilea microphylla) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf crisping and drop
Caused by letting the soil dry out fully, low humidity, or hot direct sun. The tiny leaves are unforgiving of drought. Keep soil evenly moist and humidity above 50 percent.
Root rot from overwatering
Soggy, poorly drained soil is the most common killer. Stems blacken and collapse at the base. Use a well-draining mix, a pot with drainage holes, and let the top of the soil dry slightly between waterings.
Leggy, sparse growth
Insufficient light stretches the stems and thins the foliage. Move to a brighter spot with indirect light and pinch back the tips regularly to encourage dense, bushy regrowth.
Powdery mildew
A white dusty coating that appears in high humidity with stagnant air. Improve airflow, avoid wetting the foliage in still conditions, and remove affected leaves.
Sap-sucking pests
Spider mites, mealybugs, scale, and aphids can all appear, especially on stressed plants in dry air. Inspect regularly and treat with insecticidal soap or neem oil.
Brittle, snapping stems
The succulent stems break very easily when handled or moved. Site the plant somewhere it won't be brushed often, and propagate any broken pieces as cuttings rather than discarding them.
