Buying Guide: Key Purchase Considerations
- Light and CO2: Cardinalis plants generally prefer moderate to high light. CO2 supplementation can boost growth and color, especially for denser displays.
- Placement and height: Plan for midground to background positions for best visual impact; dwarf varieties excel in foreground carpets or compact borders.
- Color and health: Purple-to-green color shifts can indicate healthy growth under proper nutrition and light. Watch for fading if lighting is inadequate.
- Maintenance: Regular trimming helps maintain shape and prevents shading of lower leaves. Rooted options are easier to reposition in clusters.
- Pest and disease prevention: Look for suppliers that emphasize pest-free guarantees and proper acclimation practices after shipping.
