Growing philodendron 'dean mcdowell' in a pot

Verdict
Ideal in pots
Pot size
15-20 cm (6-8 in) across
Mature size
Leaves commonly reach 40-60 cm long indoors (larger in ideal conditions); the rhizome can spread up to ~1 m wide over years. A slow grower best suited to wide, shallow planters rather than tall pots.

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 philodendron 'dean mcdowell' in a pot

Containers dry far faster than open ground, so philodendron 'dean mcdowell' in a pot needs checking more often than the general guidance of "Roughly weekly in the growing season; let the top 30-50% of the mix dry first" — 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.
