A traditional source of nitrogen and phosphate, it’s a popular versatile organic product for use on bulbs, shrubs, planting of trees and as a dressing on vegetables and plots. The nitrogen becomes available over a week or two of microbial action, and the phosphate is almost as available to crops as that of superphosphate. Don’t be put off by this product’s strong smell, as this gritty powder fertiliser is excellent for all round the garden.
