Growing stiff-leaved aponogeton in a pot

Verdict
Ideal in pots
Pot size
15-20 cm (6-8 in) across
Mature size
Leaves 20–58 cm (8–23 in) long, 2.5–4 cm (1–1.6 in) wide; rhizome creeps to 30 cm+ (12 in+); overall spread can reach 40–60 cm (16–24 in) in a large tank

Compost and drainage

Stiff-leaved Aponogeton likes steady moisture but not waterlogging — a tricky balance in a pot. Use a good peat-free compost with some added perlite for air, make sure the container drains freely, and mulch the surface to slow evaporation.

Watering stiff-leaved aponogeton in a pot

Containers dry far faster than open ground, so stiff-leaved aponogeton in a pot needs checking more often than the general guidance of "Permanently submerged; fortnightly 25% water changes as a minimum" — 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.
