Orchids need to be transplanted every one to two years as their growing medium breaks down and loses nutrients. For most orchids, spring is the ideal time for transplantation, but there are also other factors to consider. An orchid should be transplanted:  After the plant has bloomed and is growing new roots or leaves When the roots and plant start to overgrow the current pot When it’s not currently flowering or forming new flowers If the pot breaks If the plant becomes infested with bugs If growing medium is wet and not draining properly Pot choice for orchids is important, and this includes the size and the style. Transplanting an orchid into a pot that’s too large will force the plant to focus on root growth rather than flowering. Also, for an orchid to survive, it has to be placed in a pot with drainage holes.  Pick a pot that will allow for one to two years of growth, but nothing larger than that. If you're not sure about how much growth there will be, opt for a pot that’s just one size larger than the current one.  You can use plastic or terra cotta pots for orchids. Terra cotta pots require more frequent watering. Use pots with holes in the sides so there's lots of air flow. Opt for a shallow pot versus a deep one to prevent water buildup. Most orchids don’t grow in the ground like other plants, but instead grow on trees. Because of this, many orchids cannot grow in regular potting soil, and instead need a very loose soil that’s amended with chunks of bark and other organic matter. Popular mediums for orchids include coconut husk, sphagnum moss, perlite, fir bark, and mixtures of these. Before transplanting your orchid, give it some water three days prior to help reduce the shock of transplanting. Don’t give it more water than usual, however. Instead, give it enough to moisten the growing medium it’s currently in. Remember to fertilize your orchid once per week with a weak 20-20-20 fertilizer solution. Many orchid media are dry, and soaking the medium before transplanting will help it absorb and retain...
