The Quiet Work of a Garden

Why Your Potting Soil Is Probably Too Dense: A Guide to Mixing Your Own

There is a particular kind of late-autumn afternoon — the light going amber, the windows fogged at the edges — when the temptation is to repot everything at once. The monstera has been sulking since September. The succulent collection near the south-facing sill looks pale and waterlogged. And yet reaching for the nearest bag of multipurpose compost and calling it done is precisely the habit that keeps houseplants from ever truly thriving. The problem, more often than not, is not the plant and not the light and not the watering schedule. It is the soil itself — too dense, too moisture-retentive, too forgiving of a mixture that suits a hanging basket in a garden centre rather than a lithophyte clinging to a cliff face in Yunnan. Understanding what soil actually does, and what each of its components contributes, is the quiet shift that separates the keeper of plants from the grower of them.
