Plants, like every other living thing, need food, and plants that get the nutrients they require will be healthier more productive and produce bigger and more numerous blooms. There are six primary nutrients essential for strong plants. Oxygen Hydrogen and Oxygen are available from the air and water. Nitrogen Phosphorus and Potassium taken up from the soil.
To give soil the nutrients plants need means fertilizing. Fertilizing is necessary to build up soil for healthier plants or to replenish nutrients in fertile soil used up as plants grow. The numbers on a bag or box of fertilizer reveal the kinds and relative amounts of the nutrients inside.
The first number refers to the amount of Nitrogen the fertilizer contains. The second number is for Phosphorus. The third number refers to Potassium. There's an easy way to remember which number refers to which nutrient... they're in alphabetical order... Nitrogen Phosphorus and Potassium.
Nitrogen helps plants produce the proteins they need and creates luxurious green foliage.
Phosphorus stimulates root growth and helps the plant set buds and flowers.
Potassium helps the plants make carbohydrates and improves overall vigor and disease resistance.
Which fertilizer formulation works best depends on where and when it will be used. For growing vegetables a 5-5-5 fertilizer provides a good balance of nutrients. For lawns a high nitrogen fertilizer a higher first number will green up a lawn in the spring and summer. At the end of your lawn's growing season a fertilizer higher in Phosphorus will stimulate roots and help establish a healthy root system for spring growth.
