Philodendron
Climbing types (like the classic heartleaf philodendron) will stay smaller and more wiry trailing unsupported, but produce noticeably larger, more mature-shaped leaves once trained up a moss pole or similar support — the same principle as climbing Monstera and Epipremnum already in this KB.
Care
Tolerates medium light well, which is part of its popularity, but growth slows and leaves space out more in low light.
Water when the top few centimetres of compost have dried out; more forgiving of missed waterings than most aroids.
Peat-free houseplant compost with added bark or perlite for drainage.
Pinch out trailing stems to encourage bushier growth and prevent legginess; trim back any bare or damaged stems at any time.
A balanced feed at half strength monthly while in growth. Yellowing lower leaves on a philodendron are usually overwatering or exhausted compost rather than a lack of feed.
Stem cuttings with at least one node and an aerial root, in water or compost — quick and near-certain through the growing season. The climbing kinds root faster if the cutting is given something to cling to.

Common problems
How to spot it. Long bare stretches of stem between leaves.
What to do. Almost always insufficient light — move to a brighter spot and pinch out growing tips to encourage bushier regrowth.
How to spot it. Older leaves turn yellow and drop while new growth looks healthy.
What to do. Often just natural ageing of older leaves; if several leaves yellow at once, check for overwatering first.
How to spot it. Not a plant health problem, but a household safety note.
What to do. Contains calcium oxalate crystals like other aroids — keep away from pets and young children who might chew the leaves.
Questions
Philodendron: is it hardy?
H1b: Tender, needs above 10°C. It survives above 10 °C.
Can it grow in a pot?
Grown exclusively as a pot plant in the UK climate; trailing types also suit hanging baskets or shelves.
Philodendron: when do you prune it?
Pinch out trailing stems to encourage bushier growth and prevent legginess; trim back any bare or damaged stems at any time.
When do you feed it?
A balanced feed at half strength monthly while in growth. Yellowing lower leaves on a philodendron are usually overwatering or exhausted compost rather than a lack of feed. Feeding months, UK: April–September.
