Sowing Instructions

 

Indoors: Sow seeds in trays or small pots filled with fine seed compost from February to April. Cover lightly, keep soil moist, and maintain a temperature of 18–21°C. Once seedlings are strong enough, transplant into larger pots or directly into the garden after the last frost.

 

Outdoors: Direct sow in well-prepared, fertile soil from March to May. Space rows 20–25 cm apart and thin seedlings to 10–15 cm apart. Mulch to retain moisture and encourage blanching of stems.

 

Harvesting: Harvest when stems reach desired thickness. Leek Oarsman F1’s tender texture and mild flavour make it ideal for fresh eating, cooking, or winter storage.
