Monstera adansonii care: watering, light and repotting
Also called swiss cheese vine, monkey mask monstera, five holes plant · Monstera adansonii · Araceae family
12 d in winter
How often to water the monstera adansonii?
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.
Water when the top inch (2–3 cm) of soil is dry. On a moss pole its holey leaves grow larger; hanging, they stay small.
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 monstera adansonii 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 3 weeks is enough; the rest of the year, let it rest.
Adult size: Stems 3–6 ft (1–2 m), climbing or trailing.
Toxic to pets and children. Keep this plant out of reach and, if it is eaten, contact a vet or a poison control centre.
