About Burke's Raphionacme

Raphionacme burkei · also called Burke's Raphionacme, Burke's Wild Grape · houseplant

A South African caudiciform gem producing a large, above-ground, spherical caudex that can exceed 30 cm across, with trailing annual vines bearing small, star-shaped flowers. Summer-growing and winter-deciduous. Highly sought by caudex collectors. Demands bright indirect light, a very gritty free-draining medium, and a completely dry winter rest.

Mature size: Caudex up to 30 cm or more in diameter; annual trailing vines to approximately 45 cm.

Watch for — Root damage during repotting: Roots are sensitive and do not tolerate rough handling. Repot in very late winter or early spring just before growth resumes, disturbing the root system as little as possible. Use a slightly larger pot with fresh gritty mix.

How to tell burke's raphionacme needs repotting

Repotting on a calendar is less reliable than reading the plant. For burke's raphionacme, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot burke's raphionacme

Every 2–3 years, into bone-dry mix. Burke's Raphionacme's growth habit — perennial caudiciform geophyte with a large, near-spherical to slightly flattened above-ground caudex. produces trailing, semi-erect to vining annual stems that are deciduous. smooth, visible caudex is a key ornamental feature. — sets the pace. A South African caudiciform gem producing a large, above-ground, spherical caudex that can exceed 30 cm across, with trailing annual vines bearing small, star-shaped flowers. Summer-growing and winter-deciduous. Highly sought by caudex collectors. Demands bright indirect light, a very gritty free-draining medium, and a completely dry winter rest.

What size pot to step burke's raphionacme up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Burke's Raphionacme stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot burke's raphionacme

Spring or summer, while burke's raphionacme is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting burke's raphionacme

Repot dry. Do not water burke's raphionacme for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty highly airy, gritty free-draining mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set burke's raphionacme at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep burke's raphionacme completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for burke's raphionacme

Burke's Raphionacme wants highly airy, gritty free-draining mix. Use a blend of pumice, lava grit, and coarse clay with a small proportion of peat or leaf-mould for nutrient retention. A purely inorganic or near-inorganic cactus/succulent mix with added perlite is suitable. The caudex benefits from being raised above the soil level. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting burke's raphionacme — frequently asked questions

How often should you repot burke's raphionacme?

Every 2–3 years, into bone-dry mix for burke's raphionacme. Repot burke's raphionacme every 2–3 years into a snug pot of highly airy, gritty free-draining mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does burke's raphionacme need?

When is the best time of year to repot burke's raphionacme?

Should you water burke's raphionacme after repotting?

No — not straight away. Repot burke's raphionacme into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise burke's raphionacme after repotting?

Not immediately. Wait about 3 weeks after repotting burke's raphionacme. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
