Measure the correct ratio: For optimal results, mix 1 part fish blood and bone with 5 parts water. This ratio ensures a balanced and effective mixture. When we remove the cuttings from a lawn the leaf material contains nutrients that need to be replaced. Lawns survive but don’t thrive in the absence of a fertiliser programme. Week after week the bank of food within the soil is thrown away with the cuttings. Well-fed lawns recover from stress factors such as drought and heavy wear. In time the best quality lawns may deteriorate if important plant nutrients aren’t replaced. Growmore or National growmore to give its proper title, is an inorganic alternative to fish, blood and bone. It is a relatively modern invention due to necessity during the Second World War, as part of the dig for victory campaign, where potash was in great shortage. Potash was normally minded in Germany and as a result of war it was not readily available, and alternatives had to be found. Here’s a pro-tip: to prevent nutrient imbalances, it is recommended to start with smaller quantities of the mixture and gradually increase the dosage as needed. Regular monitoring of plant health and observing any signs of nutrient deficiencies or excesses can also help adjust the application rate accordingly.

However, if you’re preparing your garden beds for spring planting, you can incorporate some blood and bone into the soil in winter. While fish blood and bone is a natural and organic fertilizer, it is important to handle it with care. Wear gloves and avoid inhaling the dust or fumes from the mixture. Store the fertilizer in a cool, dry place away from children and pets.

Inorganic fertilisers: These are synthetic, artificial forms of plant nutrients or naturally occurring mined minerals. Inorganic fertilisers are usually more concentrated and faster acting than organic fertilisers. Examples of inorganic fertilisers include: Growmore, Miracle-Gro All Purpose Soluble Plant Food,Phostrogen All Purpose Plant Food, Sulphate of Ammonia, Sulphate of Potash, and Superphosphate and Tomorite Concentrated Tomato Food. This does not equate to an NPK ratio of 7:7:7 but actually converts to NPK of 7:3.8:5.8, so it is not a totally balanced fertiliser that some make it out to be. It contains more nitrogen than the other elements and no trace elements are present, which can be found in fish, blood and bone. If there is any skin or eye irritation, promptly wash the affected area with plenty of water and seek medical attention if necessary. When used correctly, fish blood and bone mixture improves soil fertility, enhances plant growth, and strengthens the overall health of plants. However, it is important to monitor the response of plants and soil to ensure optimal results and make any necessary adjustments to the fertilization routine.

If you are into organic gardening then fish, blood and bone is the product for you, or if you are not bothered as long as the product does the job, then you can use either. To give an idea of cost per square metre, growmore will cost around 10p and fish, blood and bone will cost around 5p for the recommended application rate. Keep the mixture away from children and pets to avoid accidental ingestion, as it can be harmful if ingested.Can be used all around the garden: Bedding plants, flowers, bushes, trees and conifers, fruit and vegetables. How often to apply It reduces the reliance on synthetic fertilizers, minimizing the risk of harmful chemical runoff into waterways. The combination of fish blood and bone provides essential nutrients like nitrogen, phosphorus, and potassium. You can use this type of fertiliser on crops as well as ornamental plants. It’s safe and natural. 4) It’s Sold in Large Quantities Application method: Consider the method through which you will be applying the mixture.
