• Small pots and potting mix
• Rooting hormone powder or gel
• Clear plastic bags or dome lids

• Water thoroughly to settle the soil and eliminate air pockets.
• Label each pot with the plant name and date.

Maintain Humidity

Finally, maintain high humidity around the cuttings:

• Place pots in bright indirect light, out of direct sun. An east facing window is ideal.

• Mist cuttings daily but avoid overwatering the soil.

Location – Keep pots consistently warm, above 65°F. Provide bottom heat if possible.

Light – Bright indirect light encourages root growth. Avoid direct hot sunlight.

Ventilation – Allow air circulation around the cuttings to prevent damp rotting.
