Frequently Asked Questions

What pest or disease commonly affects Brassica oleracea var. italica (white sprouting) and how can I control it?
Check regularly for cabbage white butterflies and caterpillars (pieris) because they rapidly chew through developing shoots. Cover seedlings and emerging sprouts with fine netting or row cover before butterflies fly, and hand-pick caterpillars as soon as you see them. If you notice leaf yellowing and a sooty, gray mold or slimy rot in damp conditions, remove affected leaves promptly and improve airflow by keeping the bed free of debris.
How often should I water white sprouting (Brassica oleracea var. italica) during the main growing phase?
During active growth toward 75 days, keep the soil consistently evenly moist—typically about 1 inch (2.5 cm) of water per week, adjusted for rainfall and heat. Water deeply to wet the root zone, and avoid letting the soil dry out fully between waterings because brassicas are prone to stress and poor, inconsistent sprout development. In hot spells, split that weekly amount into 2–3 watering sessions to maintain steady moisture.
How do I know when white sprouting (Brassica oleracea var. italica) is ready to harvest?
Harvest when the thick, tightly packed white shoots reach usable size and are firm, typically around 75 days from sowing/establishment. The shoots should be tall enough to cut cleanly at the base without pulling the plant, and the surface should look fresh and solid rather than loosening or turning yellow. Cut individual shoots as they mature to encourage a second flush if the plants remain healthy.
Botanical illustration of White Sprouting

Feather-light sprout clusters emerge in a clean, pale green-white glow, tender as fresh lace and sweetly vegetal with a gentle, nutty finish. White Sprouting forms a succession of tight, upright heads that stay crisp and pleasantly mild, ideal for turning into vibrant springtime greens. Grow it for abundant sprouting over a long season—your beds rewarded with delicate texture and continuous harvests for salads, quick sauté-style dishes, and bright, simple sauces.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 32°F before moving outdoors. Harden off for 6 days first.

Expert Note

For the best white spears, “heel up”/draw soil or compost around the stems as growth thickens while keeping plants well watered.
