If the leaves are a dark green color, this indicates that the plant is not getting enough light. The ideal leaf color for adequate light is about the color of grass, that is light or medium green. The best windows are generally southern and eastern facing ones. Don t overdo the fertilizer however. In the Autumn switch to a blossom-bloom fertilizer.
Orchids really appreciate good humidity.
If you have a humidifier in your home palce it near to your orchids. Otherwise you can place your orchid pots on a tray of flat pebbles to which water is added. Ensure sufficient air movement around your orchids to ward off infections and bacteria. Inc. PageWise makes no representations about the content published on this site.
