PlantCompost.
Organic material broken down through decomposition; also a word used regionally for prepared potting media.
What it means for your plants
Clarify whether advice means garden compost or a formulated potting compost. Their roles differ. Garden compost can be an ingredient or soil amendment, but is not a universal substitute for a container medium.
IN PRACTICE
A UK bag labeled potting compost may be a complete growing medium, while homemade garden compost is not the same product.
Put it into practice
Compare potting mix, potting soil, garden soil, and compost so you can choose the right root environment for container plants.
