Humidity: Medium to High
Substrates: (1:1:1) Lava + Pumice + Limestone Grit
Planting: Terrestrial, Lithophytic (on rocks)
Light: Medium to Very High
Many of the tropical Pinguicula originate from Mexico.
There’s a lot to love about this group of plants:
- They have beautiful and interesting foliage shapes, growth patterns, and colors
- They produce gorgeous flowers in a variety of stunning colors
- They are carnivorous
The exact care and requirements for Mexican tropical Pings vary depending on the species and their habitat, but in general they are quite adaptable.
Depending on the species, the ideal light levels may vary from medium up to extremely high. Most are adaptable though. In high light, the plants will be compact and more colorful.
Mexican Pings do best in medium to high humidity.
I prefer to keep the substrate moist most of the time, and occasionally wet for a short period, but I don’t ever keep the plants in swampy conditions. In my experience these Mexican Pings do much better when kept slightly moist and well drained.
For substrate, some people use peat moss and sand, or other similar carnivorous plant mixes. I prefer, and have had much better success, with mineral-based substrate mixes, because they drain better, last forever, and are more alkaline in pH which is a better match to where most of these plants grow in the wild.
My current mix for Mexican Pinguicula is:
- 1 part small lava
- 1 part pumice
- 1 part limestone grit
The limestone grit is optional. If you decide to add it, be sure to get coarse limestone grit, which is crushed limestone. Do not use agricultural or pelletized lime, which are completely different things.
I fertilize my Pinguicula by occasionally spraying them with Grow More Urea Free Orchid Fertilizer mixed to ¼ the strength noted on the label.
Some species have a semi-dormant period when the foliage changes form. I tend to reduce water and fertilizer slightly during that time.
