The Best Fertilizer to Use for Leeks


Leek is an herb that does not take much to grow.  But in order to produce succulent, tender and tasty leeks, you must give it the best care you can give.  One of the ways to do this is by fertilizing it properly.

This family of onions needs high nitrogen to thrive.  Ideally, it is best to apply four to as much as six inches of organic matter to the soil.  This should be mixed together with an all-purpose fertilizer before planting.

Leeks are not very heavy feeders.  The soil can also be lightly side-dressed with nitrate of soda or cottonseed meal late in May or June.  You can fertilize your crops two to three times during the summer season.

Choose a fertilizer that is low in phosphorous.  You can use well-rotted chicken manure if you want an organic fertilizer.

However, make sure not to overdo it.  Too much feeding is one of the reasons why leeks bolt.  When this happens, the neck and lower stem of the leek turns tough and woody.  Its taste will also be affected.

Refrain from fertilizing newly transplanted leeks.  Fertilizers are best applied at least one season prior to planting.
