Plantex 20-5-30 Super K Water Soluble Fertilizer

  • USA

Plantex 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, Plantex 20-5-30 will exhibit minimal acidifying activity in the soil. It is particularly useful where a change in soil pH is undesirable.


Plantex 20-5-30 Super K fertilizer, rich in potassium, is particularly recommended on ornamental crops during the finishing period. It allows plants to “harden off” by promoting the development of stronger plant tissues and thus improves their resistance in the sale rings. This fertilizer has very little impact on the pH of the substrate due to its low acidifying potential.

It is also recommended in combination with calcium nitrate for the production on open ground of tomatoes and cucumbers in greenhouse.
