More about ficus altissima 'yellow gem' in the UK
Which compost ficus altissima 'yellow gem' needs
For ficus altissima 'yellow gem' the mix to buy is peat-free multipurpose compost. Use a chunky, fast-draining mix (quality potting soil amended with perlite, bark or coarse sand) at pH 6.5-7. Good drainage is essential; this Ficus resents wet feet. A houseplant or aroid-style mix in a pot with drainage holes works well.In British garden centres the bagged growing medium is sold simply as “compost” (multipurpose, ericaceous, or loam-based John Innes), which is a different thing from the rotted garden “compost” you make in a heap — for a pot you want the bagged kind.
Peat-free compost
Buy peat-free. The sale of peat compost to home gardeners is being phased out across the UK, and the RHS recommends peat-free on environmental grounds. A good peat-free multipurpose grows ficus altissima 'yellow gem' perfectly well; the one habit to change is watering — peat-free dries faster at the surface while still moist below, so check by feel a knuckle deep rather than trusting the look of the top.
Ericaceous or multipurpose?
Ficus Altissima 'Yellow Gem' is straightforward: an ordinary peat-free multipurpose compost is right. For a big specimen or a pot it will live in for years, mixing in some loam-based John Innes No.2 or No.3 adds weight and holds nutrients longer. Ericaceous compost is not needed unless a plant is specifically a lime-hater.

What compost should I use for ficus altissima 'yellow gem' in the UK?

Can I use ordinary multipurpose compost for ficus altissima 'yellow gem'?
Yes. A good peat-free multipurpose compost is exactly right for ficus altissima 'yellow gem'. For a large or long-term pot you can mix in some John Innes No.2 or No.3 (loam-based) for extra weight and staying power.

Does ficus altissima 'yellow gem' need grit or perlite added?
Not essential, but a couple of handfuls of perlite in the mix improves aeration and guards against overwatering — useful on a cool, damp British windowsill where compost stays wet longer.
What pot and drainage does ficus altissima 'yellow gem' need?
Always a pot with drainage holes. Well-draining, slightly acidic to neutral potting mix. Stand it on a saucer, empty any water that collects after watering, and never leave the pot sitting in a full outer cover — waterlogged compost in a cool UK room is the commonest cause of root rot.
