Orchids gained their popularity as indoor plants. In their natural environment, orchids grow tangled on the tree bark, and their roots are exposed to sun, air and water.
Orchids are tropical plants, so they might think they need plenty of water. Indeed, in their natural environment they are exposed to torrential rains that can last hours or even days, but there are many species that adapt to a dry environment where rain may miss for weeks.
If you love orchids and grow them indoors, you should know some important watering rules. Otherwise their leaves will get a yellowish tint and will fall.
1. Water the orchid only in the morning. It’s important that the substrate to be damp when the night comes.
2. General rule of frequent watering:
- once a week during winter
- twice a week during summer
3. Orchids that have narrow pots will be watered more often than those with larger pots.
4. The decision of a new watering is NOT taken based on substrate dampness, because it may be dry on the outside and damp on the inside. As a watering trick, you should stick a small stick into the soil to check its dampness. If the substrate its moist it means that the watering should be postponed.
5. Watering orchids with rainwater is the best option for them, because it will provide natural nutrients beneficial for orchid’s growth. Tap water should be used with caution due to the chemical treatments it contains.
6. Orchids are always watered with room temperature water. Even if the effects don’t appear immediately, cold water watering will cause plant’s death.
7. Never, but never pour water on orchid’s leaves. If, by mistake, water gets on the leaves, you should wipe them with a paper towel.
8. The center of leaf rosette should always be kept dry. Water stagnation in the middle of the leaf rosette leads to plant’s death. If any water drop gets there, it should be removed immediately with a paper towel or cotton buds.
9. Exaggerated watering leads to leaf yellowing and plant’s decline. If you notice that the leaves are turning yellow you should know that is a sign of root rot and watering must be stopped for a few weeks.
