What fertilizer numbers to use in spring?
Numbers, numbers, numbers. We all hate them. But when it comes to fertilizer numbers what do they mean?
In short, there are two numbers to look at when purchasing fertilizer. The first is the N-P-K (nitrogen-phosphorus-potassium) number, which tells us how much of each nutrient is in the bag. The second is the percentage of water-soluble nitrogen, which tells us how much of the nitrogen contained in the bag is available to the plants.
A 20-5-10 grass fertilizer is a good basic mix to use in spring.
Conclusion
The best fertilizer for grass in spring is one that is high in nitrogen. Nitrogen is important to grass because it is used to produce chlorophyll, which gives grass its green color. The more chlorophyll a blade of grass has, the healthier and greener it will be.
