How often should you water a Phalaenopsis? Don't get it wrong
Many people like to ask how often a Phalaenopsis should be watered. In fact, the best time to water is judged by how dry or moist the medium is; you cannot make a blanket statement about watering once every few days. Depending on differences in light, temperature, humidity, ventilation, the material of the pot, the choice of potting medium, and how strong and plump the plant is, the watering interval will differ. First, let's talk about how to tell whether the sphagnum moss needs watering.

How to judge when to water a Phalaenopsis in sphagnum moss: the key points are look, weigh, touch, and press.
1. Pay attention to the weight when you usually water, and from then on judge by how the weight feels.
2. Look at the color of the sphagnum moss, the color of the roots, and the moisture on the pot wall. If the roots turn white, there is no moisture on the pot wall, and the color of the sphagnum moss becomes lighter.
3. Touch the sphagnum moss at the drainage hole at the bottom of the pot to check whether it is dry or moist; it is fine when the sphagnum moss at the bottom of the pot is slightly dry
4. Press the sphagnum moss and feel its springiness to judge whether it is dry or moist
5. Insert a toothpick to judge whether it is dry or moist; this is very suitable for beginners.
Insert a toothpick and pull it out after 10 minutes to see how dry or moist the toothpick is. If you don't know what a dry or moist toothpick looks like, soak one in water and put one in the pot, then compare. If the toothpick color is a little moist but not that moist, you can water. Don't wait until the toothpick shows no color change at all after being inserted, as that is too dry; it is when the toothpick is neither quite dry nor quite wet.
Items 1-4 need to be combined for an overall judgment; only 5 can be used as an independent judgment.
