Signs to Look for When Buying Plants Online
Before purchasing, inspect the plant images and descriptions carefully. Look for:
- Healthy foliage: No discoloration, spots, or wilting.
- New growth: Signs of active, healthy growth.
- Root health: Visible roots should be white or light tan, not brown or black.
- Absence of pests: No visible insects or webbing.
Tips for Preventing Disease After Purchase
Once your plant arrives, proper care can help prevent disease development. Follow these tips:

- Proper watering: Avoid overwatering and ensure good drainage.
- Clean tools: Disinfect pruning shears and pots before use.
