Orchids are large plants that grow a long flower shoot surrounded by blade-shaped leaves and topped by bright five-petaled flowers. These are tropical plants, but they grow in airy, dry conditions in the tropics, on tree trunks and in the canopy. In a home, they require some simple but very specific care.
Spring King Orchid
Spring king orchids, or dendrobiums, are so called for their blooming time and very large flowers. Dendrobiums are some of the largest orchids, with shoots of up to 10 inches and flowers that measure 5 inches in spread.
Pot and Growing Foundation
All orchids require dry, porous and supportive foundations that hold the roots but drain quickly and allow for good air circulation. Plant dendrobium orchids in 6-inch clay pots with drainage holes, using vermiculite, peat or fern moss, or wood chips.
Spring king orchids prefer daytime temperatures of 75 to 85 degrees Fahrenheit and nighttime temperatures of 60 to 65 degrees Fahrenheit. Beautiful Orchids suggests morning sun with afternoon shade, or artificial lighting, for these plants.
Orchids prefer dry conditions to wet, and suffer in standing water or a muddy growing foundation. Monitor an orchid's soil and water it only if the pot is dry. Waterings generally range from every five days to every 12 days, depending on the season and temperature of the growing environment. Give lilies 1/2 to 1 inch of water, and avoid pouring water directly on their leaves or stems.
Regular feedings are an important part of a spring king orchid's life. Feed the orchid with orchid-specific or 25-9-9 fertilizer once a month. Always mix fertilizer with water per manufacturer directions before you feed the plant.
