Pak choi

Brassica rapa (Chinensis Group)

Broad green leaves and crisp pale stalks form an open, upright rosette.

Make it part of your growing collection.

A LITTLE EVERYDAY CARE

Help it thrive.

A few things worth knowing.
01

Keep moisture steady

Water in dry weather and check pots regularly so growth does not stall.

02

Avoid temperature stress

Aim for mild conditions; light shade helps summer crops, while cold snaps may call for protection.

03

Choose your harvest size

Thin plants according to whether you want baby leaves or full-sized heads.
