Butterworts (Pinguicula) care instructions

 

About Mexican Pinguicula (Butterworts)
Mexican Pinguicula are beautiful and easy-to-grow carnivorous plants, known for their colorful, sticky leaves and delicate flowers. They form compact rosettes that can range in size depending on the species, making them perfect for windowsills and indoor collections. 🌿✨

---

Mature Size
Depending on the species, plants typically range from 1 to 7 inches in diameter. For example:

• P. esseriana reaches about 1 inch in diameter
• P. gigantea can grow up to 7–8 inches across under ideal conditions

---

Lighting
Provide bright light for best growth and coloration.

• A sunny windowsill works very well
• Or use full-spectrum grow lights
• Strong lighting enhances vibrant leaf colors 🌞

---

Soil / Media
Use a well-draining, mineral-free mix:

• Perlite, peat moss, and vermiculite (3:1:1 ratio)
• Lightly moisten the medium before potting
• Avoid soils with fertilizers or minerals, as these can harm the plant

---

Watering
Mexican Pinguicula have seasonal watering needs:

• During active growth, keep the soil lightly moist using distilled, rain, or reverse osmosis water
• During the winter phase, reduce watering and allow the medium to dry more between waterings
• The tray method (bottom watering) is recommended
• Avoid watering directly into the plant’s crown to avoid rot

---

Humidity
Thrives in 50–80% humidity with good airflow to prevent rot.

---

Temperature
Mexican Pinguicula prefer:

• 75–90°F in summer, but keep the soil moist
• 45–70°F in winter

---

Dormancy / Winter Phase
Most Mexican Pinguicula do not enter true dormancy. Instead, they transition into a winter succulent phase, producing compact, non-carnivorous leaves while conserving energy for the next growing season.

Simply reduce watering and slightly shorten the photoperiod during this time to keep your plant healthy and thriving year after year.

---

Feeding
Feed every 2–3 weeks with:

• Small insects
• Dried bloodworms
• Finely crushed fish food

You may also apply diluted Schultz Cactus fertilizer as a foliar spray (follow label directions carefully).

---

Potting
Use plastic pots with proper drainage to allow the medium to dry appropriately between waterings. 🪴
