After reading this paper you will have a more complete understanding of raspberry and bramble nutrition. This paper is a summary of several sources of university publications that will give the reader the necessary information on fertilization of brambles. In general most growers will use an off the shelf fertilizer analysis on bushes, when in reality brambles are like any other living thing that requires different nutrients in different ratios depending on the soil type, native material, and other amendments that may be distributed around them.
The paper discusses the importance of soil pH, nitrogen requirements, as well as phosphorus and potassium fertility of raspberries and brambles. And it does not end here; the paper goes into the secondary nutrients of calcium, magnesium and sulfur and their usage as well as application recommendations. From here the grower can also fine tune their fertility program further by looking at boron, zinc, manganese, copper and iron requirements of brambles.
