About Colima Butterwort

Pinguicula colimensis · also called Colima butterwort · houseplant

Pinguicula colimensis is a Mexican tropical butterwort from the state of Colima, bearing large, broadly oval pale-green sticky leaves with attractive pink-veined white flowers. A tropical species that stays in carnivorous growth year-round without a succulent rest phase. Adaptable and free-flowering, it is well suited to windowsill or terrarium culture.

Mature size: Rosette diameter 8–15 cm (3–6 in); flowers on slender scapes 10–20 cm (4–8 in) tall

Watch for — Root rot from overwatering: Unlike temperate species that tolerate tray waterlogging, P. colimensis prefers its roots moist but not saturated. Ensure excellent drainage, reduce watering frequency, and never leave the pot in a deep tray of standing water for extended periods.

How to tell colima butterwort needs repotting

Repotting on a calendar is less reliable than reading the plant. For colima butterwort, 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 colima butterwort

Every 2–3 years, into bone-dry mix. Colima Butterwort's growth habit — flat rosette of broad, oval, sticky carnivorous leaves; tropical species with no succulent-leaf rest phase — sets the pace.

What size pot to step colima butterwort up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Colima Butterwort 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 colima butterwort

Spring or summer, while colima butterwort 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 colima butterwort

Repot dry. Do not water colima butterwort 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 lean mineral mix: 2:1 perlite to peat or pure pumice/perlite blend 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 colima butterwort 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 colima butterwort 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 colima butterwort

Colima Butterwort wants lean mineral mix: 2:1 perlite to peat or pure pumice/perlite blend. Grows on limestone and volcanic substrates in the wild; prefers near-neutral to slightly alkaline pH (6–7.5). A mix of perlite, coarse sand, and a small amount of peat works well. Avoid nutrient-rich composts entirely. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting colima butterwort — frequently asked questions

How often should you repot colima butterwort?

Every 2–3 years, into bone-dry mix for colima butterwort. Repot colima butterwort every 2–3 years into a snug pot of lean mineral mix: 2:1 perlite to peat or pure pumice/perlite blend, 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 colima butterwort need?

When is the best time of year to repot colima butterwort?

Should you water colima butterwort after repotting?

No — not straight away. Repot colima butterwort 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 colima butterwort after repotting?

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