Move it or lose it. Now is when your cymbidium orchids need the warmth and light of the sun more than at any other time of the year. This will prompt those tall spikes of stunning flowers to start rising from the depths of their dense foliage from May to September. Put them where they get gentle morning or dappled light, either inside or out. If you’re moving them outside, make sure they’re not exposed to strong winds or frost.
