A flowering stage fertilizer with an NPK ratio of 5-25-5 is a type of fertilizer that is specifically formulated to promote flowering and fruiting in plants. The NPK ratio represents the percentage of three essential nutrients: nitrogen (N)， phosphorus (P) and potassium (K)， respectively. In this case， the fertilizer has a relatively low nitrogen content (5%)， which is beneficial during the flowering stage because it encourages the plant to focus more on producing flowers rather than leafy growth. Nitrogen is primarily responsible for promoting vegetative growth， so reducing its concentration during flowering helps redirect the plant's energy towards flowering and fruit development. The phosphorus content is high at 25%. Phosphorus is crucial for supporting flower formation， root development and overall plant health. It plays a vital role in energy transfer， nutrient uptake and the production of flowers， fruits and seeds. High levels of phosphorus during the flowering stage can enhance the size， quality and quantity of blooms. Lastly， the potassium content is 5%. Potassium， also known as potash， is essential for overall plant health and development. It aids in the synthesis of proteins and carbohydrates， improves water uptake and nutrient transport within the plant and enhances disease resistance. Potassium is particularly important during the flowering stage as it supports flower color， fragrance and the formation of healthy， robust blooms.
