If you are looking for a good starter outdoor orchid, look no further than Spathoglottis orchids. These orchids are fairly easy to grow. Unlike most epiphytic orchids, Spathoglottis orchids are terrestrial orchids and grow in soil.
Spathoglottis orchids require lots of bright, indirect light and can even tolerate several hours of direct sunlight each day. They need frequent watering during the growth period. Regular fertilization with a high nitrogen like Speciality Bio 20 is a must. These orchids thrive in warm, humid environments and prefer humidity levels around 50 to 70%.
Light
They prefer full sun to light shade; many grow well in shade house conditions. They should receive direct sunlight for at least some time of the day.
Water
Water thoroughly when the 2-3 inches of the soil becomes dry to the touch, stopping when water starts draining from the drainage holes. Avoid over-watering as Ground Orchids roots can rot quickly. The more light and warmth that your plants gets, the more water it will need, so check the soil for dryness every few days. You will not need to water as often in the winter when the plant is not actively growing.
Temperature
Being tropical in nature, they best enjoy temperatures between 20 C - 32 C. They can be grown over most of India but might need to be protected from the cold winds in the extremely cold regions during winter.
Humidity
Ground Orchids thrive on humidity, If your humidity level is less than 50%, then consider using a humidifier to increase the level to at least 60%. Filling small trays with pebbles and water and grouping indoor plants together can slightly increase the humidity immediately surrounding your plants.
Potting and Media
They like some organic material–a garden soil with some added peat should do nicely. Make sure the drainage is good, as well. Our Ready Soil is a right mix of Peat substrate, Perlite, Vermiculite and Slow-Release Fertilizer.
Fertilizer
Spathoglottis Orchids should be fed a high nitrogen fertilizer like Speciality Bio 20 at 3 ml/L of water 4 times a month for growth & Basfoliar 13-40-13 fertilizer at 3g/L once a month for flowering.
