Looking after kale plants

Seedlings should be planted firmly into moist but well-drained soil, in full sun to partial shade.

Plants will benefit from adding well-composted manure to the soil before planting. And a good mulch is also helpful to keep plants moist and weed free. Remove any flower shoots to encourage the production of plenty of healthy leaves.

Harvesting kale

Kale can be grown as a cut-and-come-again crop. Young tender leaves can be harvested for salads. If left to mature for winter greens, plants can be left in the ground through the winter and picked as required for soups and stews.

Storing kale

Kale leaves are best used when freshly picked. However, they can be blanched and then frozen to store for later use.

Kale varieties to try

  • ‘Cavolo Nero’ – a handsome Italian kale, with long, plume-like leaves that are very ornamental in winter, particularly when dusted with frost
  • ‘Black Tuscany’ or ‘Nero di Toscana’ – has green, crinkled, strap-like leaves. It is good for winter or spring greens, and can be grown as an ornamental plant
  • ‘Ragged Jack’ or ‘Russian Red’ – an heirloom variety, with frilly, red-tinged leaves and purple-red stems; it will easily self-seed
  • ‘Scarlet Curled’ – an ornamental, dwarf, curled variety with violet-green leaves that turn violet-red after frost
  • ‘Dwarf Green Curled’ – a highly ornamental, dwarf variety with curly, dark green leaves, as its name suggests
