WINTER: Please note temperate plants are dormant and will not look the same as pictured. Do not forget a heatpack if your temps are low! Especially for tropicals!

Utricularia (Bladderwort) Care Guide

Posted by Vincent Green on

This is a general care guide - it will be updated later for specific species.


Distilled, Reverse Osmosis, Rain or water with TDS under 100.

Epiphytic: Keep moist, but do not sit in deep water or they will drown. (Longifolia, Alpina, Reniformis)

Terrestrial: Can sit in water 24/7 (Sandersonii, Livida, Calycifida)

Aquatic: Obviously, submerged in water. (Inflata, Gibba)

Aqua-Terrestrial: This is not a real classification but these are ones that love water and want the water line right up to the media or even slightly over (Graminifolia, Dichotoma, Fulva)


Low to Medium light, these plants should receive around 6-10 hours of bright light, depending on the species.

When in good conditions, they will spread and flower.


Best kept in tropical conditions (Above 65 degrees). Lower can be tolerated but growth will slow.

Most aquatic ones will go dormant in the winter, forming turions.


Epiphytes: I prefer to keep them in long fiber sphagnum, sometimes with perlite/coco husk.

Terrestrials: Usually kept in pure peat or peat+perlite.

Aquatic: No media as they float freely, but peat in the bottom of the water container.
