Phostrogen's Slogans & Taglines

Phostrogen is a British plant food brand launched in 1960 by Bobby Manners, who introduced the revolutionary All Purpose Plant Food as a white, water-soluble powder. For over six decades, the brand has been a trusted staple in British gardens, delivering a balanced NPK 14:10:27 formula enriched with trace elements to promote healthy green foliage, abundant flowers, and stronger root systems across all ornamental and edible plants, seedlings, lawns, and houseplants. Core offerings originally centred on the iconic granular All Purpose Plant Food, which remains the hero product, but the portfolio has significantly expanded in recent years under SBM Life Science to include organic granular and liquid feeds, tomato food, ericaceous plant food, lawn food, and natural garden defence solutions such as Bug Plant Defence and Fungus Plant Defence. In 2022, Phostrogen underwent a comprehensive rebrand, blending heritage and modernism with refreshed packaging while welcoming the Toprose range into the family. Today, the brand continues to serve green-fingered enthusiasts across the United Kingdom with a full spectrum of plant nutrition and protection products.
