Growing humboldt's bladderwort in a pot

Verdict
Ideal in pots
Pot size
15-20 cm (6-8 in) across
Mature size
Stolons may spread 20–40 cm (8–16 in) through the host tank; leaves 5–15 cm (2–6 in); flower scapes 30–60 cm (12–24 in) with large 3–4 cm blooms

Compost and drainage

Use a quality peat-free compost with a handful of perlite for air, and make sure the pot has drainage holes. Compost in containers compacts over time, which suffocates roots — that is the main reason potted plants decline.

Watering humboldt's bladderwort in a pot

Containers dry far faster than open ground, so humboldt's bladderwort in a pot needs checking more often than the general guidance of "Keep bromeliad tank or equivalent reservoir filled with 2–5 cm of pure water at all times; change every 1–2 weeks" — especially in summer, wind, or a heated room. Check the top few centimetres with a finger rather than watering on a fixed day.

Potting on

Pot on when roots show through the drainage holes or growth slows noticeably — usually every 1-2 years for a plant this size. Move up one pot size only; jumping several sizes leaves wet compost the roots cannot reach, and that is what rots them.
