CAM orchids - mist or not to mist them, that is the question
I recently got into a discussion about watering orchids from above. I'm a proponent of the most sensible method for me, which is raining it down, so I pop my plants in the shower cabin and shower them from the top with a watering can filled with rainwater, letting the water cascade down the leaves, flush the soil, and rinse the roots. I've been doing this for many moons and hardly ever does any of my moth orchids fall ill. Detractors of this watering style have brought up some serious points, arguing that due to the stomata, through which the water could be taken up by the plants lurking beneath the leaves, and also the fact that moth orchids are CAM orchids, such watering is nonsensical and brings more risks than benefits, as plants watered in this way gather water in hard-to-reach spots, making them prone to bacterial or fungal diseases. They reckon it would be best to pour water through the pot, but making sure to steer clear of soaking the leaves. I couldn't buy into that, considering that if moth orchids often thrive in rainforests, they've clearly been evolutionarily adapted to conditions where their leaves meet water every day. However, this didn't sway my adversaries. What's your take on the matter? I know there are many seasoned orchid growers here, that you have heaps of knowledge. Do you also reckon avoiding leaf soaking for orchids is the way to go, and that it's ineffective and hazardous for them?
