Plant-Prod 21-7-7 water soluble fertilizer has a very high potential acidity. If used in a continuous feeding program, the pH should be monitored to ensure that it does not go below the desired level. It is recommended for crops such as azaleas, rhododendrons and many evergreens requiring acid soil conditions. When irrigation water has a high pH, Plant-Prod 21-7-7 will help to overcome the effect of the bicarbonate ions in the media and gradually reduce the pH for better growth of bedding plants, pot crops, cut flowers, and nursery stock in containers and in the field.
Rapid vegetative growth of forest seedlings occurs between the 4th and 16th weeks of growth. Plant-Prod 20-8-20 water soluble fertilizer should be used on a constant feed basis to encourage good top growth. This formulation contains four times more iron than most Plant-Prod fertilizers, lower phosphorus and added magnesium. It should be used for the majority of the growing season, once seedlings have a well established root system.
Plant-Prod 20-8-20 water soluble fertilizer is an all purpose, higher nitrate fertilizer is ideal for plants grown in soilless media and forms the backbone of many greenhouse growers’ nutritional programs. Over 60% of the nitrogen is in the nitrate form, making it an ideal formulation for any time of the year, even during low light conditions. Use alone or in rotation with Plant-Prod 15-0-15 Cal Plus or Plant-Prod 14-0-14 Cal Mag to provide a balanced fertilizer program.
Available in a No Dye formulation.
Plant-Prod 20-5-30 water soluble fertilizer is recommended for summer feeding of roses, geraniums and other ornamentals. Greenhouse tomatoes and cucumbers grown in soil respond well to this formula when used alone or in combination with potassium nitrate. This high potassium fertilizer is ideal for use when plants are maturing and blooming. It allows the plants to establish heavier, thick-walled cells which results in efficient water utilization. Since the potential acidity is very low, this fertilizer will exhibit minimal acidifying activity in the soil. It is particularly useful where a change in soil pH is undesirable.
Plant-Prod 20-2-20 water soluble fertilizer helps keep the pH low and contributes very little phosphorus. This formulation in combination with Plant-Prod 14-0-14 is ideal for plugs and bedding plants. Plant-Prod 20-2-20, because of its high potential acidity is very useful in maintaining an ideal pH balance in plug media. Plant-Prod 20-2-20 can also be used for production of blue hydrangeas and easter lilies when excess phosphorus is not required.
Plant-Prod 20-20-20 water soluble fertilizer is a general purpose water soluble fertilizer is very effective on all types of plants. Its balanced formula may be used whenever a more general formulation is required. Its high percentage of ammoniacal and urea nitrogen will provide rapid green up and leaf expansion while the balanced phosphorous and potassium will encourage root and shoot growth.
Plant-Prod 20-10-20 water soluble fertilizer without colorant has been specially developed to meet the particular needs of professional interior designers.
Plant-Prod 20-10-20, water soluble fertilizer has 60% of its nitrogen in the nitrate form, and a complete minor elements package including a higher level of molybdenum, as required for soilless mixes. This is an ideal formulation for use in low light conditions.
Plant-Prod 18-6-20 water soluble fertilizer contains over 60% of the nitrogen in the nitrate form, a high level of magnesium, an increased level of molybdenum, a low boron level and chelated micronutrients.
Plant-Prod 15-30-15 water soluble fertilizer is ideal for hydrangeas since the high phosphorus content ties up excess aluminum in the soil which causes a strong pink colouration in the blooms. Acid-loving plants such as african violets respond well to this formulation due to its high potential acidity. Use during the early stages of crop growth, when many greenhouse crops require extra phosphorus, particularly tomatoes and cucumbers grown in soil. 15-30-15 can be used to remedy phosphorus deficient soils.
