🪴 Care & Maintenance Guide

🌞 Light

• Best: Very bright, indirect light indoors, or several hours of gentle sun

• Outdoors: Full sun to partial shade (morning sun is ideal)

• Tip: More light = stronger reds/oranges/yellows

• Avoid: Deep shade (faded color, leaf drop) and harsh afternoon sun in extreme heat (possible scorch)

💧 Watering

• Water when the top 1–2 inches of soil begin to dry

• Keep soil evenly moist but never soggy

• Tip: Crotons dislike drying out completely—steady moisture helps prevent leaf drop

🪨 Soil

• Rich, well-draining potting mix

• Add perlite for extra drainage if needed

• Drainage holes required for container-grown plants

🌡️ Temperature & Humidity

• Ideal temperature: 65–85°F (18–29°C)

• Prefers moderate to high humidity (helps prevent crispy edges and leaf drop)

• Avoid cold drafts and temperatures below 60°F (16°C)

🌿 Fertilization

• Feed every 4–6 weeks during spring and summer

• Use a balanced houseplant fertilizer (follow label directions)

• Reduce feeding in fall/winter

✂️ Pruning

• Pinch or trim to encourage a fuller, bushier shape

• Remove damaged leaves as needed

• Rotate the pot occasionally for even growth

⚠️ Common Issues

• Leaf drop: sudden changes in light/temperature, drafts, or inconsistent watering

• Faded color: not enough light

• Brown edges: low humidity or underwatering

• Pests: spider mites/scale/mealybugs—treat early if detected
