Orchids need ample water but should be allowed to dry out some between waterings. One way to check for when it’s time for watering is by poking your finger about an inch into the growing media. If it’s dry, give it some water; otherwise, let it be. Indoor orchid plants also need adequate humidity: about 50 to 70 per cent. There are various ways to increase the humidity in your home. Place a water-filled saucer or tray of pebbles beneath plants; mist plants daily; or use a humidifier. Fertilise orchids weekly or bi-weekly while they are producing new growth, and decrease to monthly or bi-monthly intervals once they mature. Discontinue altogether once the plants go dormant. Additional orchid care tips include repotting, which is normally done every other year. If your orchids suddenly stop blooming but have suitable light, temperature, and humidity, then repotting may be necessary. Also keep an eye out for signs of pests or disease. Orchids are occasionally affected by mealybugs, scale, and aphids. These can usually be washed off or treated with insecticidal soap.
