Extremely cold-hardy — tolerates -20°C and below. Smooth blue-green leaves. Mild flavour. Overwinters in mild climates without protection.
Brassica oleracea (Curly)
vegetableA fellow Brassicaceae — similar growing habits to Siberian Kale
Start Siberian Kale indoors about 6 weeks before your last frost, keeping seeds in cooler soil (around 10–18 °C). Seeds usually come up in around 7 days. Move seedlings out once the danger of frost has passed, in partial sun, spaced about 45 cm apart. Expect to harvest in roughly 70 days.
Siberian Kale seed rarely stays viable beyond 4 years — track what's still worth sowing.
Water: Medium · Height: 75 cm · Soil: Rich, moist, slightly alkaline
Coccinellidae
The one predator here where the adults hunt as hard as the larvae do.
Aleyrodidae
A puff of white when you brush the leaf, and stickiness underneath.
These three thrive alongside Siberian Kale — and alongside each other.
