From Cross Exotics…. The best orchid fertilizer available! This is our own fertilizer formulated by commercial orchid grower Xavier G. de Loubresse for Dendrobium, Paphiopedilum, Phalaenopsis, and other orchids. It quickly greens up plants, even on slower species, making long lasting deep green shiny leaves with frequent blooms. It is a complete NPK fertilizer with Calcium & Magnesium.

This fertilizer also works great for carnivorous plants, Nepenthes, and Amorphophallus. It is very low urea - Urea Nitrogen can be useful for orchids but tends to be too strong for Nepenthes, causing pitchering to stop. 

The fertilizer is an easy to use water soluble blend that is dissolved and watered into the substrate; not slow release pellets. We recommend soil fertilizing for best results rather than foliar spraying. 

The difference:

There is 3 primary forms of Nitrogen used in fertilizers, Nitrate, Ammonium, and Urea. Most fertilizer research has been for crop plants which typically prefer Nitrate. As many orchids are epiphytes or from highland areas, nitrate tends to be scarce due to high rainfall, with primarily Ammonium nitrogen remaining. Thus many orchids grow better with a fertilizer that includes some Ammonium, typically around a third to half of the total supplied N. 

Our fertilizer balances these ratios, supplying about a third of total Nitrogen as ammonium and also has adjusted micronutrients, to stop yellowing leaves from iron chlorosis. The CalMag and nitrate keeps leaves firm and prevents root burn. We do not use low phosphate formulas because trials showed slower growth and soil pH issues with low phosphate. Potassium is higher for strong flowering, similar to the original MSU formula. It's time to start growing your plants faster and better, the results of our fertilizer speaks for itself in the photos - incredibly green plants.
