Care
Exposure
Choose a sunny location with at least 6 hours of direct sunlight daily for optimal growth. This plant also appreciates well-ventilated areas with minimal shade. However, it can adapt to partial shade on rich soil.
Watering
Keep the soil moist during the growing season, especially in hot weather or when grown in containers. Water regularly without letting the soil dry out completely, but avoid waterlogging. Reduce watering in winter or after harvesting leaves.
Soil
Prefer well-draining soil rich in organic matter and slightly alkaline to neutral. Beta maritima tolerates coastal soils, including those with traces of salt. Adding compost in spring improves fertility and structure.
Fertilizing
Apply a balanced fertilizer in spring when vegetation starts. If growing the plant for its leaves, light feeding every two months supports production. Avoid excess nitrogen, which promotes foliage at the expense of plant robustness.
Pruning and harvesting
Pinch back young stems regularly to encourage branching and a more compact shape. Leaves can be harvested progressively as the plant develops. Cut back to ground level before winter to simplify cleanup at the end of the growing cycle.
Diseases and pests
Watch for aphids and spider mites, particularly in warm conditions. Good air circulation reduces the risk of fungal diseases. If infection occurs, favor biological treatments or mechanical removal of affected parts.
Did you know?
Beta maritima is the wild ancestor of cultivated beet (Beta vulgaris), with which it shares its genetic heritage. Found naturally on cliffs and beaches along the Mediterranean and Atlantic coasts, this halophilic species tolerates extreme coastal conditions and has been used for centuries by coastal populations for its nutritional properties.
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.
