Gastroenterologists have extensive training in the diagnosis and treatment of conditions that affect the esophagus, stomach, small intestine, large intestine (colon), and biliary system (e.g., liver, pancreas, gallbladder, bile ducts). Gastroenterology is a subspecialty of internal medicine.
Apply a nitrogen rich fertilizer, at 1/4 strength of the manufacturer's recommended dosage, to the soil around the orchid plants every time they are watered. Allow the soil around the orchid plant to dry out between watering. Apply the fertilizer to the soil right after watering. Use a teaspoon to administer the fertilizer. If your orchid plants are surrounded by bark, move the bark aside so the fertilizer blends well with the soil and isn't hindered by the bark.
Look for a fertilizer with 20 percent or less nitrogen: High amounts of nitrogen, much more than 20 percent, are not necessary to grow the best orchids no matter what media they are grown in. Too much of any nutrient cannot be used by the orchid plant and, as a result, merely ends up as a pollutant.
