How to grow Mexican Pinguicula (butterworts)
Mexican butterworts are the most widespread group of Pinguicula found in Central America. A key characteristic is the changing appearance of their leaf rosettes throughout the year. Below is a concise guide How to grow Mexican Pinguicula (butterworts), structured according to their specific needs:
Light conditions: A windowsill with sufficient diffused light is ideal; these plants are not demanding when it comes to light. However, more light improves coloration. West- or east-facing windows are best, though most plants also tolerate a north-facing window well.
Temperature: Maintain normal room temperature. During winter, they can tolerate a temperature drop to around 10°C, though this is not essential.
Substrate: Use clean fibrous peat mixed with coarse silica sand or perlite and crushed limestone in a 2:2:1 ratio.
Humidity: Mexican butterworts do not have high humidity requirements. The plants do not need misting.
Watering: During the growing season in summer, the plants should always stand in water. An ideal water level is approximately 1 cm. In autumn, gradually reduce watering to help the plants adapt to winter. During winter, the substrate should be dry or only slightly moist. Watering is gradually resumed in spring.
Fertilizing: During the growing season, the plants can be „fed“ with insects if they cannot catch their own prey. If prey is available, the plants will capture it on their own.
