In simple language, it is called the NPK value of fertilizer.
NPK is visible on the fertilizer container. Indeed, NPKs represent three important nutrients called Nitrogen (N), Phosphorus (P), and Potassium (K). All of these have their importance. Also, they have different effects on any plant.
People use nitrogen (N) to increase the growth of leaves and stems. Phosphorus (P) is important for flowers, seeds, and fruits. Whereas Potassium (K) is good for the whole plant. This helps to grow roots & stems and the enlargement of leaves, fruits, and seeds.
What is the meaning of 10-20-40 fertilizer written on the container of fertilizer? It says that the container contains 10% Nitrogen, 20% Phosphorous, and 40% Potassium by total volume.

Best Fertilizer For Dahlias
We love the dahlia for its flowers. That’s why we plant it in the garden or container. The more flowers, the better. Fertilizing the dahlia becomes necessary for more flowers.
A fertilizer that has a good amount of phosphorus and potassium but a low amount of nitrogen is best for dahlia flowers. Phosphorus excites flowering. Potassium gives the plant strength to withstand disease attacks. Whereas nitrogen only encourages the growth of stems and leaves. While it greatly reduces the flowering. If the fertilizer is high in nitrogen, you will see greenery on the dahlias instead of flowers.
A 5-10-10 or 10-20-20 composition will serve as the best fertilizer for dahlias. If you want, you can also use 5-10-15 fertilizers. Use them at the rate of 1 kg per 9.5 square meters (2 pounds per 100 square feet).
