Understanding Orchid’s Basic Needs
Orchids are beautiful and exotic plants that require proper care to thrive. Understanding their basic needs is essential to keep them healthy and prevent brown leaves.
Light Requirements
Orchids need indirect light to grow and bloom. Direct sunlight can burn their leaves and cause them to turn brown. A good rule of thumb is to place them near a window that faces east or west, where they can get bright but indirect light. If the leaves start to turn yellow, it may be a sign that they are getting too much light.
Watering Schedule
Overwatering is one of the most common reasons why orchids die and turn brown. They need to be watered once a week, or when the top inch of the potting mix feels dry to the touch. It’s important to let the water drain out of the pot completely, as standing water can lead to root rot and brown leaves.
Temperature and Humidity Levels
Orchids prefer warm and humid environments, with temperatures between 65 and 80 degrees Fahrenheit. They also need good air circulation to prevent fungal diseases. To maintain proper humidity levels, place a tray of water near the orchid or use a humidifier.
