What's It For? - Phostrogen

Phostrogen is a specially formulated all-purpose plant food in the form of a white, water-soluble powder. It contains nitrogen to promote healthy green foliage; potash to develop abundant flowers and fruit and make plants drought and disease resistant; phosphate to encourage a strong, healthy root system; and essential trace elements to keep plants healthy.

For convenience, it is normally applied as a solution in water. It can be used regularly throughout the growing season for all types of plants, both indoor and out. Apply plant food solution round the roots of plants as far out as the foliage reaches, using as much solution as when watering thoroughly.
