Lacinato kale is exceptionally cold-hardy, tolerating temperatures down to below -20°C, and is typically transplanted once seedlings have grown 5-6 true leaves. Harvest by picking individual leaves as needed once the plant is established, leaving the central growing point intact so it keeps producing.

Core growing advice on this page is checked against named horticultural sources — see References.

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing. How we check our facts.

How this guide is put together

The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against Canadian hardiness-zone and frost-date data, with provincial agriculture and university extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
