fertilizer application on Dracaena
Quick answer
If your Dracaena has fertilizer application, the most likely cause is: NPK 19:19:19 at 1 g/plant/month is optimal for Dracaena marginata 'Bicolor' in 20 cm pots; rates above 2 g/plant cause diminishing returns and growth reduction due to fertilizer salt accumulation in the root zone.
Start here:
- 1. Start with 1 g NPK (19:19:19) dissolved in water per plant per month, applied one month after transplanting rooted cuttings
- 2. For enhanced growth, supplement with monthly foliar spray of Fe+Mn+Zn trace elements at 50-100 ppm concentration
