Fertilizing |
 |
Sunflowers respond well to a balanced fertilizer based on soil test, usually a 1-2-3 NPK ratio is best, with a need for boron and other trace elements on lighter soils. Foliar fertilizers of liquid NPK on plants increases yield 62% with one application and 97% with two applications.
You can also add a bit of sulfate of potash, this normally helps flowering plants, providing potassium, as well as giving regular feeds of a complete seaweed fertiliser during the growing period.
