Asparagus is a hardy perennial vegetable that lasts up to two or three decades in a planned and well-maintained garden, according to University of Illinois Extension. Proper care for asparagus includes annual fertilisation with the best type of fertiliser.


Phosphorous fertiliser, added to the soil before planting, encourages healthy root development of asparagus, according to the Arizona Cooperative Extension.

Annual Fertilization

A balanced fertiliser works best for asparagus in the early spring, before shoots emerge, according to the Iowa State University Extension. Nitrogen fertiliser works best when applied in June after harvesting ends. Just 0.045 Kilogram of pure nitrogen covers a 100-square-foot area.

Natural Fertilizer

Manure or other organic fertiliser choices such as blood or bone meal and wood ash also work well as asparagus fertiliser, according to the Purdue University Extension.
