Orchids, these exotic and delicate flowers, are prized for their beauty and diversity. However, in order for them to flourish and reveal their full potential, careful care is necessary, especially when it comes to watering. In this article, you will find information on various techniques and tips for watering orchids that will keep them lush and colorful.
1. Understanding the Water Needs of Orchids
1.1 Types of orchids
There are many varieties of orchids, each with its own specific needs. The most common include:
- Phalaenopsis : These are one of the easiest orchids to grow. They prefer slightly moist but not soggy soil.
- Cattleyas : These orchids like good drainage and a soil that dries quickly between waterings.
- Dendrobiums : They require more frequent watering during the growing season, but should be allowed to dry out completely during the dormant period.
1.2 Seasonality
Orchids’ water requirements vary with the season. In summer, heat and humidity increase watering requirements, while in winter, watering frequency should be reduced to prevent root rot.
2. Effective watering methods
2.1 Immersion watering
An effective method of watering orchids is submerged watering. Here’s how to do it:
- Fill a bucket or sink with room temperature water .
- Submerge the orchid pot in water for 10–15 minutes . This allows the roots to absorb water from below.
- Remove the pot and drain it for a few minutes to prevent water from standing.
2.2 Surface watering
If you prefer surface water, follow these steps:
- Use a watering can with a thin stream to direct the stream of water .
- Water the substrate gently , avoiding wetting the leaves and flowers. This reduces the risk of fungal diseases.
2.3 Fogging
Misting can also be beneficial, especially in dry environments. Spray the leaves and roots with water, but make sure that the moisture does not remain stagnant.
3. Watering frequency
3.1 General rule
The general rule is to water once a week. However, before watering, it is essential to check the soil moisture. Press your finger into the soil:
- If it’s dry , it’s time to water.
- If it is still damp , wait a few days before checking again.
3.2 Adaptation to climate change
Adjust watering frequency to your climate. During periods of heat or intense sunlight, your orchids may need more frequent watering.
4. Water quality
4.1 Types of water
The quality of water used to water orchids is crucial:
- Rainwater : This is an ideal solution because it is natural and chemical free.
- Distilled Water : A good alternative, especially if your tap water contains a lot of chlorine or minerals.
- Tap water : If using tap water, let it sit for 24 hours to allow some of the chemicals to wash out.
