Firm soil around stems — loose soil causes loose buttons. Flavour improves dramatically after frost. Remove yellowing lower leaves as sprouts develop.
Brassica oleracea var. capitata
vegetable
A fellow Brassicaceae — similar growing habits to Brussels Sprouts
Start Brussels Sprouts indoors about 12 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 full sun, spaced about 60 cm apart. Expect to harvest in roughly 100 days.
Brussels Sprouts seed rarely stays viable beyond 4 years — track what's still worth sowing.
Water: Medium · Height: 90 cm · Soil: Rich, firm, moist, alkaline (pH 6.5–7.5)
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 Brussels Sprouts — and alongside each other.
