Which compost mini moth orchid 'sogo vivien' needs
For mini moth orchid 'sogo vivien' the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Use a free-draining bark or bark-and-moss blend in a pot with ample drainage; clear plastic pots help you monitor roots and let light reach them. Never pot a Phalaenopsis in regular potting soil, which suffocates and rots the roots.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 mini moth orchid 'sogo vivien' 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?
Mini Moth Orchid 'Sogo Vivien' does not want a rich, water-holding compost — it wants sharp drainage. Cut peat-free multipurpose roughly half-and-half with horticultural grit, sharp sand or perlite, and always pot into a container with drainage holes. A "cactus and succulent" bagged mix is a ready-made shortcut.

Compost for Mini Moth Orchid 'Sogo Vivien' in the UK — frequently asked questions
What compost should I use for mini moth orchid 'sogo vivien' in the UK?
Use peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Use a free-draining bark or bark-and-moss blend in a pot with ample drainage; clear plastic pots help you monitor roots and let light reach them. Never pot a Phalaenopsis in regular potting soil, which suffocates and rots the roots.

Can I use ordinary multipurpose compost for mini moth orchid 'sogo vivien'?
Not on its own — multipurpose compost holds too much water for mini moth orchid 'sogo vivien' and will rot the roots. Cut it roughly 50:50 with horticultural grit, sharp sand or perlite so it drains fast.
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 mini moth orchid 'sogo vivien' perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does mini moth orchid 'sogo vivien' need grit or perlite added?
Yes — mini moth orchid 'sogo vivien' must have sharp drainage. Add about one part horticultural grit or perlite to one part compost, and always use a pot with drainage holes.
What pot and drainage does mini moth orchid 'sogo vivien' need?
Always a pot with drainage holes. Open epiphytic orchid mix (medium-grade bark, perlite, sphagnum, charcoal).
