Conophytum obcordellum · also called heart cone plant, patterned conophytum · houseplant

Conophytum obcordellum is a dwarf South African mesemb forming clusters of small, smooth, fused leaf-bodies topped with fine reddish dotting and a slit. It flowers in autumn, often with night-scented white-cream blooms. A winter-grower, it rests through summer beneath a papery sheath. It demands mineral soil and a precise seasonal watering rhythm; ASPCA status is unconfirmed.

Mature size: Individual bodies around 1.5-3 cm; clumps spread slowly to 10-15 cm wide and stay very low.

How to tell conophytum obcordellum needs repotting

Repotting on a calendar is less reliable than reading the plant. For conophytum obcordellum, 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 conophytum obcordellum

Every 2–3 years, into bone-dry mix. Conophytum Obcordellum's growth habit — clump-forming dwarf mesemb that multiplies into dense low mats of small fused-leaf bodies. — sets the pace. Conophytum obcordellum is a dwarf South African mesemb forming clusters of small, smooth, fused leaf-bodies topped with fine reddish dotting and a slit.

What size pot to step conophytum obcordellum up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Conophytum Obcordellum 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 conophytum obcordellum

Spring or summer, while conophytum obcordellum 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 conophytum obcordellum

Repot dry. Do not water conophytum obcordellum 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 sharp, mineral gritty mix with little organic content 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 conophytum obcordellum 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 conophytum obcordellum 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 conophytum obcordellum

Conophytum Obcordellum wants sharp, mineral gritty mix with little organic content. Use mostly pumice, grit and coarse sand with a small amount of compost in a well-draining pot. Heavy or rich soil holds too much water and causes rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting conophytum obcordellum — frequently asked questions

How often should you repot conophytum obcordellum?

Every 2–3 years, into bone-dry mix for conophytum obcordellum. Repot conophytum obcordellum every 2–3 years into a snug pot of sharp, mineral gritty mix with little organic content, 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 conophytum obcordellum need?

When is the best time of year to repot conophytum obcordellum?

Should you water conophytum obcordellum after repotting?

No — not straight away. Repot conophytum obcordellum 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 conophytum obcordellum after repotting?

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