Peatlands store large volumes of carbon and support distinct habitats, which is why extraction for horticulture has come under regulatory pressure. For gardeners the practical question is how the replacement mixes behave.
Watering behaviour
Many peat-free mixes look dry at the surface while remaining moist below, which prompts over-watering by anyone judging by appearance. Weight of the pot, or a finger below the surface, is a more reliable check.
