Care for an orchid after it blooms by trimming back the spike, placing the plant in indirect sunlight, keeping it at a consistent temperature and watering it every week. Move the plant to a cooler area to stimulate new blooms.
After the blooms drop from an orchid, examine the spike. If the spike appears off-color or begins to yellow, trim it down to the base of the plant. If the stem looks healthy, you can either leave it intact or trim it back to the second node so that it flowers again. After trimming the spike, cover the cut area with some fungicide or ground cinnamon to prevent disease. At this time, re-pot the plant as necessary. Orchids thrive in tight pots, so only re-pot the plant if the roots start growing over the lip of the pot.
Water the plant at a reduced rate, about once a week, so that the soil is just this side of dry. Place the plant in bright indirect sunlight in an area with temperature between 65 to 75 degrees Fahrenheit. You can move the plant to a cooler area to stimulate new growth, but first give the orchid a period to rest before getting it to bloom again. Once a new spike appears, resume fertilizing it.
