Care

Exposure

Pink garlic prefers a location in full sun for optimal flowering and better vigor. A minimum of 6 hours of direct sunlight per day is recommended. In very hot regions, a little afternoon shade can be beneficial.

Soil

Choose a well-draining, light, and rather chalky soil, as pink garlic dislikes stagnant moisture. Poor to moderately fertile soil works perfectly; enrich it before planting if needed with compost. Avoid overly clayey soils by lightening them with sand or gravel.

Watering

Water regularly during the growth phase (autumn-spring), but moderately once established. After flowering, gradually reduce watering until it stops completely in summer. In pots, check that water drains well and don't let water pool.

Fertilizing

Fertilizer is generally not necessary if your soil contains compost. At the start of the growing season, a light balanced fertilizer can stimulate growth. Avoid excess nitrogen, which would promote foliage at the expense of flowering.

Pruning and harvesting

Remove spent flowers to encourage bulblet production. Let the foliage dry completely before cutting it back, as it nourishes the underground bulb. Dig up the bulbs in summer after the aerial part has fully dried.

Diseases and pests

Pink garlic is generally robust. Watch for powdery mildew in case of excessive humidity. Bulbs can rot if exposed to prolonged moisture; good drainage prevents this problem. Few pests target it under normal conditions.

Did you know?

Pink garlic has been cultivated since ancient times in the Mediterranean, where the Egyptians appreciated it not only for its delicate fragrance, but also for its very ornamental pale pink flowers. Unlike common garlic, its bulb remains small and its flavor is much milder, which made it popular in ornamental gardens rather than at the dinner table.

Where to buy it

Plant the bulbs in autumn for spring flowering. Pick a plant with healthy foliage and roots that are not exposed. Best time: from September to November.
