About Candy Cane Sorrel

Oxalis versicolor · also called Striped Wood Sorrel, Candy Stripe Oxalis · flowering

Candy Cane Sorrel is a delightful South African bulbous Oxalis producing white flowers with vivid red-striped backs that spiral closed like candy canes in overcast weather or at night. Forms a neat low clump of clover-like leaves. Ideal for pots and alpine or sunny borders. Contains soluble oxalates — mildly toxic to pets if consumed in quantity.

Mature size: 10-15 cm tall and wide in flower

Watch for — Dormancy confusion: The plant goes fully dormant in summer; the pot may look dead. Mark and withhold water until autumn regrowth.

How to tell candy cane sorrel needs repotting

Repotting on a calendar is less reliable than reading the plant. For candy cane sorrel, 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 candy cane sorrel

Every 2–3 years, into bone-dry mix. Candy Cane Sorrel's growth habit — low, clump-forming bulbous perennial with trifoliate clover-like leaves — sets the pace. Candy Cane Sorrel is a delightful South African bulbous Oxalis producing white flowers with vivid red-striped backs that spiral closed like candy canes in overcast weather or at night. Forms a neat low clump of clover-like leaves. Ideal for pots and alpine or sunny borders. Contains soluble oxalates — mildly toxic to pets if consumed in quantity.

What size pot to step candy cane sorrel up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Candy Cane Sorrel 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 candy cane sorrel

Spring or summer, while candy cane sorrel 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 candy cane sorrel

Repot dry. Do not water candy cane sorrel 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 free-draining sandy or gritty compost 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 candy cane sorrel 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 candy cane sorrel 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 candy cane sorrel

Candy Cane Sorrel wants free-draining sandy or gritty compost. A sharp, well-drained mix prevents bulb rot. Use a bulb or cactus compost with 25% added grit. In the garden, plant in raised beds or rock gardens with excellent drainage. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting candy cane sorrel — frequently asked questions

How often should you repot candy cane sorrel?

Every 2–3 years, into bone-dry mix for candy cane sorrel. Repot candy cane sorrel every 2–3 years into a snug pot of free-draining sandy or gritty compost, 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 candy cane sorrel need?

When is the best time of year to repot candy cane sorrel?

Should you water candy cane sorrel after repotting?

No — not straight away. Repot candy cane sorrel 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 candy cane sorrel after repotting?

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