Light- Most orchids require bright light but indirect sunlight. However, some orchids, such as Vanda orchids, require full sun. If your orchid gets scorched, do not detach the damaged leaves unless the plant has several additional healthy leaves.
Mist- Most orchid houseplants come from humid, tropical regions, so do best in a humid atmosphere. In most centrally heated homes the air is dry, so mist the foliage every two to three days using tepid water.
Watering- Overwatering is the most common way to kill orchids. To avoid giving your plant too much water, always lift the pot first to check if it feels heavy – water only when it feels light. Fill a container with water, submerse the pot, leave for 10 minutes, leave to drain, and place back in its pot. Empty excess water after half an hour.
Pests- The most common orchid pests are scale insects and mealybugs. Signs of infestation include stickiness on the leaves or nearby surfaces, or black sooty mould. Scale insects can be found on the leaf surfaces (above and below) and flower stalks, while mealybugs prefer new leaves. It’s easy to remove pests by hand, using a soapy sponge to clean the leaves. Alternatively, spray with an insecticide.
Encouraging your orchid to flower again -Once all the flowers have fallen, cut off the stem just above a visible joint (node). This may stimulate the production of another flower stem, which you should clip to a support. If no shoot appears and original stem turns straw-coloured, then remove it at the base. Most other orchids won’t flower twice on the same stem, so cut off spent stems immediately.
