Bio Leaf Orchid Grow

Created for Orchids

For over 35 years Orchid Grow has been used by home orchid growers and commercial growers. It was originally developed by Brian Pryor who is an orchid grower, hybridiser and a chemist. Combining his knowledge of growing orchids with chemistry he formulated Orchid Grow to supply the nutrients in the correct quantities as required by orchids.

Complete Nutrient Profile

Orchid Grow's formulated to include 16 essential nutrients and there is no need to supplement with any other nutrients.

Some fertilizers fail to include calcium, sulphur and adequate levels of trace elements. For example, sulphur is needed to initiate flowering, while boron, sets the flower buds and calcium produces strong, long-lasting stems. 

Another important feature of Bio Leaf Orchid Grow is its ability to stabilize the pH in orchid potting mixes. Buffering the pH is extremely important for good growth. Huge fluctuations in pH will cause the plants to sulk and affect the absorption of certain minerals.

Some fertilizers use urea or too much ammonium nitrogen. Not only does this make the potting mix extremely acidic it burns the roots. So, to help we have taken away all the guesswork. By simply adding the stock solution to water all the nutrients required to support orchid growth and flowering are supplied in the correct proportions. 

  • Nitrogen – 11%
  • Phosphorus – 2%
  • Potassium – 8%
  • Calcium – 8.5%
  • Magnesium 1.23%
  • Sulphur, Iron, Zinc, Boron, Copper, Molybdenum, Manganese, Nickel, Sodium, Cobalt and Chlorine.
