Calathea

Goeppertia spp. (syn. Calathea) · Houseplant

Grown for its boldly patterned leaves, which fold up at night and open again in the morning. It is not hard to keep but dislikes change: dry air, hard water and cold drafts show up quickly as brown edges. A warm, humid, softly lit spot suits it best.

When?

Repot or divide in spring or early summer. Avoid moving it around in winter, when low light and dry heated air already stress it.

Step by step

  1. Place in medium light away from windows with hot afternoon sun.
  2. Water with soft, room-temperature water; rainwater or filtered water helps if tips brown.
  3. Keep humidity above about 50% with a humidifier or pebble tray.
  4. Feed monthly in spring and summer at half strength.
  5. Trim brown leaves at the base of the stem.
  6. Keep away from heaters, air conditioners and cold doors.
  7. Divide in spring by separating clumps with their own roots.
