The easiest method is to sow seeds directly into the ground.Seeds are best sown in rows that are 30 cm apart and around 1 cm deep. Sow seeds but not too deeply on the trench. Cover with stain, water, and label for your convenience. After 4 to 5 weeks when the seedlings have foliage, thin to leave plants every 15 cmGROWING REQUIREMENTSWATERINGLeeks require regular watering for optimum development and should be watered once a week by soaking the soil to a depth of around 18 inches.PESTSProblems like leaf blighting, rotting seeds that are covered in mold, discolored root tips, leaves turning pale then yellow, stunted growth, wilted leaves, fluffy white growth on the base of the bulb which spreads up to the bulb to storage leaves etc are caused by pest attacks. The pests vulnerable to this crop are - Onion white rot, Leek rust, Leek moth,Thrips, Purple blotch.SOILLeeks prefer well-drained and rich soil, high in organic matter with an optimum pH ranging from 6.2 to 6.8.SPOTThe best place for growing leeks is where they can receive plenty of sunlight.TEMPERATURELeek seeds germinate best at a temperature around 25 °C (77°F).HOW TO HARVESTLeeks develop slowly and take about 100 to 120 days to reach maturity.Leeks are ready for harvest when the stalk has reached 3.5 cm (1 in) in diameter. Once plants get to roughly the size of a pencil, you can begin harvesting them.Harvest by carefully loosening the plant with a garden fork so as to prevent any damage.Be sure to harvest leeks before flowering occurs.Leeks are best used right off but can also be stacked away in the refrigerator for several weeks.
