Soil Requirement to Grow Leeks
Leeks thrive well in compost rich soil.
So, you must add 1/3 of vermicompost, 1/3 of sand or coco peat and 1/3 of garden soil. As this plant grows in well-drained soil, you can add coconut coir.
The growing medium should allow the excess water to flow easily and at the same time must be able to retain moisture.
According to University of Minnesota, potting soil for leeks must have a pH of 6.0 to 7.0.
You can use fertilizers to improve growing of stems and leaves.
Add dry compost/manure at the surface of the soil and cover it with a layer of garden soil.
Fresh manure may attract bacteria and it can damage the growth of your vegetable plant.
Make sure your fertilizer is free from weed-killer, because it may kill your plant as well.
