I regularly use Grow Better’s Premium Potting Mix. Do I also need to add a slow release fertiliser when I’m potting up new plants or repotting older ones?
No. Grow Better’s Premium Potting Mix already contains slow release fertiliser that will supply sufficient nutrients for three months or more after potting up. It also contains a natural growth stimulant (X Facta) that will help plants to settle in quickly. Additional fertiliser may be added after about six months.
