This indoor plant soil guide explains how potting mix structure, drainage, moisture retention and aeration affect roots grown in containers. It covers how to recognise a mix that stays too wet, becomes compacted or dries at the wrong rate, as well as how amendments can change those properties. Use the overview to understand the principles, then open the associated plant pages for species-specific care. A mix suitable for a moisture-loving plant may be unsuitable for a succulent or carnivorous plant, so avoid treating one recipe as universal. The linked profiles help you connect soil choices with each plant’s watering, light and care requirements before repotting.

How can I tell if indoor plant soil drains too slowly?
Water may remain on the surface, the pot may stay heavy for a long time, or the mix may smell stale. Check that the drainage hole is open before changing the mix.
What should I do with compacted potting mix?
Repot into a fresh, appropriately structured mix and gently remove loose exhausted material without unnecessarily damaging healthy roots. Use a container with working drainage.
Why does potting soil stay wet for too long?
The mix may hold too much water, the pot may be oversized, drainage may be blocked, or the plant may be using water slowly because of low light or cool conditions.
Can I use the same potting mix for every indoor plant?
No. Root aeration and moisture needs differ, so check the individual plant page before selecting or modifying a mix.
How can I prevent soil problems after repotting?
Match the mix and container to the plant, keep drainage holes clear and water according to the moisture in the pot. Do not assume a fixed schedule suits every season.
Should old potting mix be reused?
Inspect it first for compaction, pests, disease symptoms and poor structure. If its condition is doubtful, replace it rather than transferring a possible problem.
