Heartleaf philodendron care: watering, light and repotting
Also called philodendron, philodendron brasil, sweetheart plant · Philodendron hederaceum · Araceae family
12 d in winter
How often to water the heartleaf philodendron?
Allow about 7 days between waterings in spring and summer, and 12 days in autumn and winter, when growth slows down. These rhythms apply to a room with its favourite light: in a darker room the plant drinks less; in a brighter one, it drinks more.
Very forgiving; let it trail or train it up a pole.
Misting every 7 days helps keep the air humid around its leaves, especially in winter when central heating dries the house out.
What light does it need?
The heartleaf philodendron likes bright but filtered light: near an east- or west-facing window, or a little back from a south-facing one. Direct afternoon sun can mark the leaves.
Repotting and fertiliser
Repot every 2 years, ideally in April, into a pot only slightly bigger than the last one. As for fertiliser, from April to September, feeding every 30 days is enough; the rest of the year, let it rest.
Adult size: Stems 3–10 ft (1–3 m).
Toxic to pets and children. Keep this plant out of reach and, if it is eaten, contact a vet or a poison control centre.
Common problems
Yellow leaves
Cause: Too much water. What to do: Let the top inch or so of soil dry out.
