Blood and bone is not good for Proteas. While it may be suitable for other plants that require regular feeding, Proteas have specific nutritional needs that are not met by blood and bone or other similar products.
Proteas, being native to South Africa, have adapted to their natural environment where nutrient levels are generally low. They have evolved to be able to extract and utilize nutrients efficiently from the soil. Therefore, adding blood and bone, which is a high-nutrient fertilizer, can disrupt the natural balance of nutrients that Proteas require.
Blood and bone is primarily made from animal by-products, such as dried blood and crushed bones. While it does contain nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth, the ratio of these nutrients may not be suitable for Proteas. They prefer a lower level of phosphorus and higher levels of other micronutrients such as iron, manganese, and zinc.
Using blood and bone or similar fertilizers can lead to an imbalance in the nutrient levels, which can inhibit the growth and development of Proteas. It can also result in the accumulation of salts in the soil, which can be harmful to these plants. Proteas are adapted to grow in nutrient-poor soils, so excessive nutrient levels can cause nutrient toxicity and other negative effects.
Instead of using blood and bone, it is recommended to use fertilizers specifically formulated for native Australian plants or Proteas. These fertilizers are designed to provide the necessary nutrients in the correct ratios for optimal growth and flowering. They often contain lower levels of phosphorus and higher levels of micronutrients to meet the specific needs of Proteas.
In addition to avoiding blood and bone, it is also advisable to steer clear of products like dynamic lifter, manures, and mushroom composts when growing Proteas. These products may contain salts or nutrient imbalances that can be detrimental to the health and growth of Proteas. It is best to choose fertilizers that are specifically labeled for use on Proteas or native Australian plants.
Blood and bone is not recommended for Proteas as it can disrupt the nutrient balance and potentially harm these plants. It is important to use fertilizers specifically formulated for Proteas or native Australian plants to ensure optimal growth and flowering.
