Soil Requirement to Grow Leeks

Leeks thrive well in compost rich soil.

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.
