About Tina butterwort

Pinguicula 'Tina' · also called Tina butterwort, Tina Mexican butterwort · houseplant

Pinguicula 'Tina' (P. agnata × P. zecheri) is one of the most beginner-friendly Mexican butterwort hybrids, forming a flat rosette of lime-green glistening leaves that trap fungus gnats year-round. It blooms prolifically with pale lavender flowers and undergoes a compact succulent winter phase rather than true dormancy.

Mature size: Rosette 8–12 cm (3–5 in) in diameter

Watch for — Stunted growth and yellowing from tap water: Dissolved minerals in tap water accumulate in the root zone and cause nutrient toxicity (paradoxically). Always use mineral-free water. If leaves yellow and growth stalls, flush the pot repeatedly with distilled water and repot into fresh mix.

How to tell tina butterwort needs repotting

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

Every 2–3 years, into bone-dry mix. Tina butterwort's growth habit — compact flat rosette, typically 6–12 cm across when fully mature, cycling between a broad carnivorous summer phase and a tight succulent winter phase without true dormancy. — sets the pace.

What size pot to step tina butterwort up to

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

Spring or summer, while tina 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 tina butterwort

Repot dry. Do not water tina 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 gritty mineral carnivorous plant 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 tina 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 tina 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 tina butterwort

Tina butterwort wants gritty mineral carnivorous plant mix. Use a free-draining, nutrient-poor mineral mix: equal parts coarse sand, perlite, and pumice (or a 2:1:1 perlite-to-peat-to-sand ratio). Avoid standard potting compost entirely. Shallow, small pots (5–8 cm) suit this compact species well, as its root system is minimal. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting tina butterwort — frequently asked questions

How often should you repot tina butterwort?

Every 2–3 years, into bone-dry mix for tina butterwort. Repot tina butterwort every 2–3 years into a snug pot of gritty mineral carnivorous plant 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 tina butterwort need?

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

Should you water tina butterwort after repotting?

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

Not immediately. Wait about 3 weeks after repotting tina 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.
