Cucumber Fertilizer 8-16-36 | Chelated Micronutrients | Hydroponics, Soil & Foliar Application

Greenway Biotech Cucumber Fertilizer 8-16-36 is a water-soluble fertilizer for cucumbers, squash, pumpkins, gourds, watermelon, cantaloupe, and the other cucurbits named on its label. It guarantees 8% nitrogen (6.5% nitrate, 1.5% ammoniacal), 16% available phosphate (P₂O₅), and 36% soluble potash (K₂O), with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum.

The label’s soil rate is 2.8 grams per plant every 4 to 6 weeks. With a soil test, size a bed by the potash the test recommends. In hydroponics, dose it to a potassium target and keep it in a separate stock tank from calcium nitrate.

It contains no calcium or magnesium and little nitrogen for its potash, so plan those nutrients separately. Keep to the crops on the label, because it contains boron. Weigh it. Packed in Madera, California, in 1 to 25 lb sizes.
