GT Orchid Bloom features a complete balanced and pH buffered fertiliser formula with a nitorgen drop shifting the plant's focus to flowering. Ideal for your Orchids, Hoyas and other flowering plants with similar nutritional requirements and sensitivities, such as African Violets. Originally developed for the renowned Kew Royal Botanic Gardens in London, home to the famous Kew Gardens' annual Orchid Festival.



GT Orchid formulation is available in two formulas: Orchid Grow and Orchid Bloom. 


During the Blooming (reproductive) phase, mineral requirements are not the same as the Growing (vegetative) phase. The biggest nutritional variation is during the vegetative phase (when growing foliage), versus the reproductive state (when flowering). At first sight of a spike or peduncle, or new buds on existing spurs, shift from the GROW to the BLOOM formula. Continue feeding BLOOM until flowering finishes, then shift to back to GROW.


GT Orchid Bloom formula contains all 12 essential nutrients: Nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, boron, zinc, copper and molybdenum, and organic minerals without urea or chloride, all required for the reproductive (blooming) phase.


  • Size: 250mL bottle
  • One bottle makes up to 80L of solution.
