This is a chemical fertiliser first invented during World War Two that provides equal amounts of all three main nutrients. However, blood, fish and bone is more preferable to Growmore due to its slower release of nutrients, allowing plants to take them up more efficiently.
The biggest difference is with the macro nutrients or NPK in the products. Fish meal is high in nitrogen (N) and fish bone meal is high in phosphorous (P). Nitrogen affects vegetative growth and general plant health while phosphorus (P) is important for healthy roots and is used to promote blooming and flower set.
Blood meal is dried and powdered animal blood and bonemeal is ground animal bones. Both are great options for adding nutrients back into the soil, and they're both considered all-natural and organic.
And although bone meal and blood meal sound similar and are both organic fertilizers, they differ in the nutrients they contribute to help plants grow. Blood meal is high in nitrogen while bone meal provides phosphorus and calcium.
Because the phosphorous in bone meal requires soil with a pH below 7, combining it with nitrogen-rich blood meal can help lower the pH of your soil and make the phosphorous more available to your plants. Or you can mix either of the meals with another fertilizer, like manure or guano.
Bone meal fertilizer is only effective in soil with a pH level under seven. Remember to test your soil before using bone meal. If your soil's pH level is above seven, use a different kind of fertilizer to raise the acidity and lower the pH level.
Unlike blood meal, bone meal won't burn your plants if you add too much. If your soil testing indicates a shortage, add bone meal to your soil to help plants grow and flower.
During soil preparation: Sprinkle bone meal fertiliser evenly over the soil or add to planting compost. Make sure it's mixed well. If the weather is dry, water in well.
Ideal for all round use - Shrubs, Vegetables, Root crops and Herbaceous plants. Blood Fish and Bone Fertiliser Powder is a general purpose plant food for strong healthy growth. Blood, Fish and Bone fertiliser is a plant food provides a rapid boost to flowers, fruit and vegetables.
You can apply Fish, Blood and Bone every 4-6 weeks to sustain good soil fertility. Apply 70g/sq. m around the base of established plants.
Applied throughout the growing season, Blood, Fish and Bone can be used prior to sowing or planting or as a top dressing. Although it should be watered in, try not to use before rainfall. During application, avoid the fertiliser lodging on leaves or stems and do not exceed the recommended application information.
Use as Recommended
Over a period of about four months, soil microbes digest the organic fertilizer, creating food for plants. One application per growing season is all you need.
Blood meal and bone meal both come from animals; are used as an organic, slow-release fertilizer; and are sold in a form that looks powdery. They both can burn plants when used in excess and can attract dogs.
Rather than using bone meal as your source of phosphorus, try soft-rock phosphate. Dig 6 pounds into your plot. For potash, try 1 pound of kelp meal or 8 1/2 pounds of crushed granite, which Jeavons says will last for 10 years, slowly releasing potash and trace minerals.
Bone meal is phosphorus-rich and is best used to fertilize flowering plants such as roses, tulips, dahlias, and lilies. Plants like root crops such as radishes, onions, and carrots, and other bulbs also benefit from bone meal. Use bone meal to mix with gardening soil of the right pH balance.
Bone meal increases phosphorous in soil for optimal spring gardening results. Essential in the development of strong root systems, this element is released into the soil for up to four months. Slow, steady delivery of nutrients helps you grow plenty of big, blooming flowers, fruits, and vegetables.
Bonemeal can be used for a wide variety of ornamental and edible plants. Apply bonemeal before sowing or planting out, use it as a top dressing for established border plants in spring, and around fruit trees and bushes in autumn.
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.
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.
It's not very difficult. You can make your own by adding two tablespoons of bone meal to a gallon of water or liquid fertilizer. Mix thoroughly, then apply it directly to the soil or sprinkle it lightly on the foliage of your plants.
And finally, a last problem with bone meal: it tends to attract vermin. Humans may not notice it, but it has a bit of a dead animal smell that other animals do pick up. If you apply it, it's not uncommon for animals (rats, dogs, squirrels, skunks, raccoons, etc.) to dig your plants up.
Bone meal is ideal for sensitive crops that flourish with slow-release phosphorus; It is especially useful for flowering and fruiting plants, such as indoor roses; Bone meal can lead to optimum results for vegetables with a small application.
