Yes, one could make a specific plant food for a specific plant. However, that would be impractical. There are too many variables, including: weather, growing media, type of crop, and cultural practices. Nelson Plant Food makes plant foods that generally benefit a wide variety or type of plant grown under a wide set of circumstances. Commercial growers that we sell to, with hundreds of varieties of plants grown under a multitude of conditions, use only a few types of plant foods. The ingredients can be blended to meet the needs of the plant and the practices of the grower. We will blend a plant food to meet the feeding regimen of any plant or grower.
