Dracaena fertilizer requirements
Quick answer
For Dracaena, fertilizer requirements come down to this: Dracaena marginata 'Bicolor' grown in 20cm pots showed that growing media significantly affects nutrient uptake. Pure peatmoss produced highest N (2.85%), K (2.75%), Fe (441ppm), Mn (255ppm), and Zn content in leaves. Peat + sand (1:1 by volume) produced higher phosphorus (0.39%). The media affects not just physical structure but also chemical availability of nutrients.
Start here:
- 1. For maximum N, K, Fe, Mn, Zn in Dracaena leaves: use pure peatmoss as growing media
- 2. For maximum P content: use peat + sand (1:1 by volume)

How to meet Dracaena fertilizer requirements
- 1
For maximum N, K, Fe, Mn, Zn in Dracaena leaves: use pure peatmoss as growing media
- 2
For maximum P content: use peat + sand (1:1 by volume)
- 3
For trace element optimization: supplement with Fe+Mn+Zn at 50-100ppm monthly
- 4
Avoid over-fertilization: NPK at 4g/plant decreased all growth parameters and nutrient content
- 5
Leaf nutrient analysis can guide fertilization — target N: 2.4-2.9%, P: 0.26-0.35%, K: 1.9-2.4%
Keeping Dracaena in range
For maximum nutrient uptake in Dracaena: use peatmoss media. Feed monthly with NPK at 1g/plant — higher rates (3-4g) decreased nutrient content and growth. Supplement with trace elements (Fe, Mn, Zn at 50-100ppm) for optimal leaf color and health.
