PlantControlled-release fertilizer.
A fertilizer designed to release nutrients over time, often using coated granules.
What it means for your plants
Release behavior depends on the exact product and conditions. Record the dose and application date, and account for existing feed before adding another fertilizer. The label’s duration is not a precise countdown for every room.
IN PRACTICE
Coated granules applied during repotting may still be supplying nutrients when a liquid-feeding reminder appears.
Put it into practice
Compare liquid feeds, soluble powders, and controlled-release granules for indoor plant care and choose a manageable routine.
