Which compost yesterday-today-and-tomorrow needs
For yesterday-today-and-tomorrow the mix to buy is peat-free ericaceous (lime-free) compost. Prefers slightly acidic soil just below pH 7. Use a loamy mix amended with peat moss, composted bark or pine needles plus perlite for drainage. Alkaline soil causes iron chlorosis (yellowing leaves); correct with chelated iron.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 yesterday-today-and-tomorrow 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?
Yesterday-Today-and-Tomorrow is a lime-hater: it needs an acidic, lime-free ericaceous compost. In ordinary (limey) multipurpose it slowly yellows between the leaf veins as it locks out iron. Buy a bag labelled "ericaceous", and in a hard-water area water with rainwater where you can, since tap water is slightly alkaline.

Compost for Yesterday-Today-and-Tomorrow in the UK — frequently asked questions
What compost should I use for yesterday-today-and-tomorrow in the UK?
Use peat-free ericaceous (lime-free) compost. Prefers slightly acidic soil just below pH 7. Use a loamy mix amended with peat moss, composted bark or pine needles plus perlite for drainage. Alkaline soil causes iron chlorosis (yellowing leaves); correct with chelated iron. In UK garden centres this is sold simply as "compost" — the bagged growing medium, not garden-made leaf-mould — so match the description above rather than a brand.
Can I use ordinary multipurpose compost for yesterday-today-and-tomorrow?
No — yesterday-today-and-tomorrow needs an acidic, lime-free (ericaceous) compost. Standard multipurpose is too limey and will slowly cause yellowing between the leaf veins (lime-induced chlorosis). Buy a bag labelled "ericaceous".
Should the compost be peat-free?
Yes. Sales of peat compost to home gardeners are being phased out in the UK, and the RHS recommends peat-free for environmental reasons. Modern peat-free multipurpose composts grow yesterday-today-and-tomorrow perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does yesterday-today-and-tomorrow 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 yesterday-today-and-tomorrow need?
Always a pot with drainage holes. Rich, well-draining, moisture-retentive acidic 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.
