Expert tips
The key tip
Allium ramosum requires full sun and poor, dry to normal soil. Enrich sparingly, or the plant becomes soft and flops over.
The common mistake
Watering regularly or enriching the soil with compost: the bulb becomes bloated and weak, then rots in winter.
The pro's trick
Multiply by dividing the small bulbs that form around the perimeter.
Care
Exposure
Fragrant garlic thrives in full sun, ideally at least 6 hours per day. This exposure promotes abundant flowering and vigorous foliage. A sunny location is essential to optimize the aromatic concentration of the leaves.
Watering
Water moderately when planting and during active growth periods. Once established, fragrant garlic tolerates drought well thanks to its underground bulbs. Avoid excess moisture, especially in winter, to prevent rot.
Soil
Well-drained, light to medium soil is preferable. Fragrant garlic adapts to different soil types but dreads permanent waterlogging. Enrich the soil at planting time with well-decomposed compost.
Fertilizing
A spring application of fertilizer is generally sufficient. A balanced fertilizer or one slightly rich in potassium promotes better flowering. Avoid excessive nitrogen applications which would favor foliage at the expense of flowers.
Pruning and cutting
Remove faded flowers to extend flowering and promote bulb regeneration. Leave the foliage in place until it completely dries out in autumn, which allows the bulb to replenish its reserves.
Diseases and pests
Fragrant garlic is generally very resistant to diseases and pests. Well-drained soil and good air circulation minimize risks. In case of excessive moisture, watch for the appearance of bulb rot.
Did you know?
Fragrant garlic, though less well-known than classical cultivated garlic, has been used for centuries in Central Asia for its aromatic and culinary properties. Its common name 'fragrant' refers to its characteristic odor when handled, milder and less pungent than that of its allium cousins. It is a melliferous plant that attracts pollinators thanks to its delicate small white or pale pink flowers.
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.
