pH • pH is defined as minus the decimal logarithm of the hydrogen ion activity in a solution.
pH • pH is a measure of the acidity or basicity of a solution.
pH • A pH of 7 is said to be neutral. • A pH greater than 7 is said to be basic or alkaline. • A pH less than 7 is said to be acidic.
pH • A pH of 6.2 – 6.8 is ideal for growing roses. • The pH can be lowered by adding sulfur. • The pH can be raised by adding limestone.
pH • A proper pH doesn’t guarantee the presence of desired nutrients. • The importance of a proper pH is to provide maximum availability of nutrients.
Fertilizer • Primary nutrients that are added to the soil are referred to as fertilizers.
Fertilizer • Chemical fertilizer – synthetically produced. • Organic fertilizer – comes from natural sources.
Fertilizer • Almost all fertilizers, both chemical and organic, tend to lower the pH or make soil more acidic.
Nutrients • A nutrient is anything that nourishes or promotes growth.
Nutrients • As much as 95% of a plant is made of carbon, hydrogen and oxygen which are obtained from the air and water. • All remaining nutrients are obtained from the soil.
Nutrients • The six most commonly used nutrients after carbon, hydrogen and oxygen are called macronutrients. • The elements needed by plants in lesser amounts, and rarely devoid in most soils, are called micronutrients.
Macronutrients • Nitrogen (N) • Potassium (K) • Calcium (Ca) • Magnesium (Mg) • Phosphorus (P) • Sulfur (S)
Nitrogen • Stimulates growth of tall, strong canes , good blooms and rich dark foliage.
Potassium (Potash) • Promotes root growth and bloom color.
Calcium • Holds cell walls together and promotes stability and early growth. Makes a sturdier plant.
Magnesium • Promotes chlorophyll formation and interacts to produce greener foliage and healthy, disease-resistant plants.
Phosphorus • Stimulates root growth, producing quality plants and big blooms. Also hastens plant maturity adding to winter hardiness.
Sulfur • Raw material for amino acids and proteins needed for plant health. Also lowers pH.
Micronutrients • Iron • Manganese • Boron • Copper • Zinc • Molybdenum • Chlorine
Micronutrients • Only small amounts of micronutrients are needed in a rose’s diet, but a lack of one or more may cause a serious decrease in the availability of macronutrients.
Element Components Of A Typical Plant • Oxygen 45% • Carbon 44% • Hydrogen 6%
Element Components Of A Typical Plant • Nitrogen 2% • Phosphorus .5% • Potassium 1% • Calcium .6% • Sulfur .4% • Magnesium .3% • This represents 99.8% of the components.
Soil Analysis • The only way to know the makeup of the soil in your garden is to have a soil analysis performed by a laboratory.
N:P:K • Most commercial fertilizers contain the three main nutrients needed for growth, nitrogen (N), phosphorus (P) and potassium (K). • Nitrogen is expressed as the percent of the single element (N), phosphorus as the percent of phosphoric acid (P2O5), and potassium as the percent of potash (K2O).

Three Big Questions • What fertilizers do I need to use? • What dosage do I need? • How Often do I feed?
What Fertilizer Do I need To Use? • Check the pH and add necessary amendments to bring the pH into the range of 6.2-6.8. • Get a soil analysis and add any amendments suggested. • Use fertilizers that bring the macronutrients into proper balance. • Ask rosarins with a similar soil for recommendations.
