The Plant-Prod 30-8-8 WIN Tree water soluble fertilizer constitutes a suspension when mixed with water. It can be applied, either by injection in the soil or at the base of trees and shrubs. It is recommended for spring and autumn fertilizations.

Crops such as cut flowers, container nursery stock and field grown vegetables respond well to this formula. Plant Prod 28-14-14 water soluble fertilizer can be used for foliar feeding due to its very low salt index and high level of urea nitrogen. Use during periods of vegetative growth when plants have a high nitrogen requirement. Use to correct nitrogen deficiency where soil or tissue tests show low nitrogen.

Plant-Prod 24-10-20 water soluble fertilizer is ideal for lowering the pH in the stock tank. It contains urea phosphate, which keeps drip lines clean and clear from plugging.

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 20-5-30 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 20-10-20 water soluble fertilizer without colorant has been specially developed to meet the particular needs of professional interior designers.
