Care

Sunlight

Place your Brassica montana in full sun for optimal growth: it needs at least 6 hours of direct light daily. It also tolerates light partial shade in hot climates. Avoid prolonged shade, which would reduce its vigor.

Watering

Water regularly during active growth, keeping the soil moist but never waterlogged. Reduce watering in winter when the plant slows down. In mountains or cool climates, it often relies on natural moisture.

Soil

Grow it in well-drained, preferably chalky soil, characteristic of its natural mountainous habitat. Improve poor soil with some well-decomposed compost before planting. Avoid overly compact or acidic soils.

Fertilizing

Apply a balanced or nitrogen-rich fertilizer in spring to support leaf growth. A single application is usually sufficient; plants from cold regions don't need excessive fertilization.

Pruning and cutting

Pinch young stems in spring to promote compact branching and a dense shape. Remove spent flowers to extend flowering. In late autumn, cut the plant back lightly or let it naturally dry out.

Diseases and pests

Watch for aphids and flea beetles, common pests of Brassicaceae. Good air circulation prevents fungal diseases. If infested, treat promptly with biological methods or regular manual cleaning.

Did you know?

Brassica montana is a lesser-known botanical cousin of cultivated cabbages and turnips, sharing the same genetic heritage. Native to the rocky slopes of the Mediterranean and Asia Minor, it has long interested alpine botanists for its remarkable adaptation to altitude and chalky soils. Its exceptional hardiness makes it a valuable mountain herb for exposed and difficult gardens.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
