Growing floating aponogeton in a pot

Verdict
Ideal in pots
Pot size
12-15 cm (5-6 in) across
Mature size
Floating leaves 3–11.5 cm (1–4.5 in) long, 1–3 cm (0.4–1.2 in) wide; petioles 7–35 cm (3–14 in) long; modest space requirement, suited to tanks from 30 cm (12 in) depth with open surface

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 floating aponogeton in a pot

Containers dry far faster than open ground, so floating aponogeton in a pot needs checking more often than the general guidance of "Permanently submerged bulb with floating leaves; fortnightly 20–25% water changes" — 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.
