So, what fertilizer is high in nitrogen? Natural fertilizers that are high in nitrogen include: sodium nitrate, feather meal, blood meal, hoof & horn meal, hair, fish meal, crab meal, animal tankage, bat guano, soybean meal, cottonseed meal, fish emulsion, manure, & compost.
Can you overuse blood and bone? Like all fertilisers, you should only apply blood and bone at the recommended rates. If you add too much, the excess may eventually leach out of your garden soil and end up in local waterways which is not good for the natural environment.
Natural bone meal contains only trace amounts of nitrogen, usually about 0.7 to 4 percent. However, if you buy pre-made bone meal, it's likely to have nitrogen added to it. This gives your plants a nutritional boost from a well-rounded soil amendment.
Blood and Bone is a good natural source of all three of the major nutrients. Used as a general-purpose food, for a wide range of plant types. Having some phosphorus makes it particularly good for stimulating strong, healthy root growth.
Seasol is not, strictly speaking, a fertiliser because it contains only low levels of nitrogen and phosphorus. Seasol can be used as an alternative to other fertilisers, such as nitrogen-based fertilisers.

The good thing about blood & bone is that it is an organic product which will not burn your plants as the nutrients are released slowly.
When planting, mix the fertilizer in with the backfill soil. If your plant's already in the ground, sprinkle the bone meal on top and then rake over the soil to mix it in. For bulbs and other spring-blooming plants, add bone meal as well.
Epsom salt – actually magnesium sulfate – helps seeds germinate, makes plants grow bushier, produces more flowers, increases chlorophyll production and deters pests, such as slugs and voles. It also provides vital nutrients to supplement your regular fertilizer.
Spread evenly around the plant in early Spring and Autumn. Avoid disturbing any surface roots. VEGETABLES: For best results plants should be evenly fed during growing season, 150g per m2 during early Spring, mid-Summer and Autumn or as required to maintain healthy growth.
