We get this question very often and that is why we decided to write about it.  The three numbers on the label represents the value of three macronutrients used by the plants. NPK represents Nitrogen (N), Phosphorus (P), and Potassium (K) and the numbers like 20-20-20 or 19-19-19 means the concentration of these elements in the fertilizer. How plants respond to the...

Nutrients are very important for all plants and living beings including orchid plants. Most plants obtain the nutrients and moisture they need from the soil. Soil or Terrestrial plants use their roots to absorb these nutrients. As most orchids are epiphytes that grow on the trees they can not benefit from the soil’s richness. Instead, they create their own mini nutrient gardens by trapping wind-blown plant and animal matter, grains of soil, mineral flakes, bird droppings and other nutrients between their tangled roots where they can be absorbed by the plant from the moisture around the roots. However this is...

The easiest way is to use a hand-held sprayer or a motorized sprayer, and spray the leaves as well as into the pots until fertilizer begins to run out of the pots.
