What do the numbers on the fertilizer bag mean?
In order, the three numbers represent the percent nitrogen (N), percent phosphate (P2O5) and percent potash (K2O) contained in the bag. This formula is a national standard for fertilizer labeling. For example, a bag of 15-10-20 contains 15% nitrogen, 10% phosphate and 20% potash. Every 100 lb of this fertilizer contains 45 lb of plant nutrients.
There are three numbers listed on each bag of fertilizer. These are literal percentages of N-P-K that are in that bag of fertilizer. For instance, if the numbers read 31-3-10, 31% of the bag is nitrogen, 3% is phosphorus, and 10% is potassium. The numbers will always be printed in the same order N-P-K. Very often, the numbers do not add up to 100%. Other minor elements and fillers can also be included in the bag. WHAT DOES EACH MAJOR ELEMENT DO? NITROGEN • Promotes vigorous blade, leaf and stem growth. • Encourages dark green color. • Assists in chlorophyll production. • Improves overall plant health, quality, and density. • Aids in tolerance to heat, cold, and drought stress. PHOSPHORUS • Promotes early plant development • Hastens plant maturity. • Promotes bloom and root development.. POTASSIUM • Improves tolerance to drought, disease and heat • Increases winter hardiness. • Aids in water uptake. • Enhances overall health and vigor. WHAT EFFECT DOES LIME HAVE ON FERTILIZER?

The numbers on the front of the fertilizer package (i.e., 10-10-10 or 28-3-3) indicate the percentage of primary nutrients — nitrogen, phosphorus and potassium — in the bag. The first number represents nitrogen (N), which is the primary nutrient for growth and greening. The second number, phosphorus (P), aids in root development and strengthens the plant. Used correctly, this nutrient is very beneficial. However, there have been environmental concerns around misused phosphorus impacting lakes, rivers and bays. As with all fertilizers, please follow the instructions and use the product responsibly. The third number, potassium (K), strengthens plants against stresses such as cold temperatures, drought and disease.
The first number is Nitrogen. Nitrogen is the plant food that is essential for strong stems, healthy leaves, and deep green foliage, especially in turfgrass. The second number is Phosphate.Phosphorus promotes healthy root systems and is especially important to the growth of young plants such as newly transplanted plants and seedlings. It also stimulates flowering. The third number is Potash.Potassium promotes flowering and fruit production. It is also the plant food essential for plant vigor, winter hardiness and disease resistance. 7. 99% of all plant material die from too much water or not enough water. When planting hand water in all plants and ensure good drainage. Leaves turn yellow from too much or too little water. Check to see if the plant is too dry or too wet. 8.
