Which compost hindu rope plant needs
For hindu rope plant the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. A loose, airy medium of potting mix with plenty of orchid bark and perlite, plus charcoal or pumice, so the roots get maximum air. Sharp drainage is critical for this rot-prone cultivar. It flowers best slightly pot-bound; repot infrequently, every 2-3 years.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 hindu rope plant 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?
Hindu Rope Plant 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.
