About Ibarra's Butterwort

Pinguicula ibarrae · also called Ibarra's butterwort, Ibarrae butterwort · tropical

Pinguicula ibarrae is a Mexican butterwort first collected from foggy limestone cliff faces near Tlanchinol, Hidalgo, where humidity stays high year-round. Unlike many Mexican Pinguicula, it rarely enters a full succulent dormancy and tends to retain its broad, strap-shaped carnivorous leaves even through drier periods, making it one of the more forgiving Mexican species to cultivate. Grow it in a loose, alkaline, mineral-rich mix and provide bright indirect light; never use tap water high in minerals. Neither Pinguicula ibarrae nor the genus Pinguicula appears on the ASPCA Toxic & Non-Toxic Plants list — the genus is not a recognised toxic group — however, the sticky digestive mucilage could cause mild gastric upset if ingested; classify as mildly-toxic until an authoritative listing confirms safety.

Mature size: Leaf rosette 5–12 cm diameter; flower scapes reach 10–15 cm bearing white to pale violet blooms.

Watch for — Root rot from acidic or waterlogged soil: P. ibarrae is adapted to fast-draining alkaline limestone substrates. Peat-based or perpetually waterlogged mixes cause crown and root rot within weeks; ensure good drainage and maintain an alkaline pH.

How to tell ibarra's butterwort needs repotting

Repotting on a calendar is less reliable than reading the plant. For ibarra's 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 ibarra's butterwort

Every 2–3 years, into bone-dry mix. Ibarra's Butterwort's growth habit — low flat rosette of sticky oval-to-strap-shaped leaves radiating from a central growing point, typically 5–12 cm across. — sets the pace.

What size pot to step ibarra's butterwort up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Ibarra's 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.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot ibarra's butterwort

Spring or summer, while ibarra's 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 ibarra's butterwort

Repot dry. Do not water ibarra's 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 alkaline mineral mix: equal parts perlite and vermiculite with a small amount of crushed limestone or lime chips 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 ibarra's 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 ibarra's 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 ibarra's butterwort

Ibarra's Butterwort wants alkaline mineral mix: equal parts perlite and vermiculite with a small amount of crushed limestone or lime chips. Avoid pure peat or acidic mixes — this species comes from limestone outcrops. A teaspoon of horticultural pellet limestone per 10 cm pot raises pH to the preferred slightly alkaline range. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting ibarra's butterwort — frequently asked questions

How often should you repot ibarra's butterwort?

Every 2–3 years, into bone-dry mix for ibarra's butterwort. Repot ibarra's butterwort every 2–3 years into a snug pot of alkaline mineral mix: equal parts perlite and vermiculite with a small amount of crushed limestone or lime chips, 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 ibarra's butterwort need?

When is the best time of year to repot ibarra's butterwort?

Should you water ibarra's butterwort after repotting?

No — not straight away. Repot ibarra's 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 ibarra's butterwort after repotting?

Not immediately. Wait about 3 weeks after repotting ibarra's 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.
