Here’s a question I received via email from Bev :
“I have a Phalaenopsis Orchid. I think I have over watered it and now all the blooms have fallen off except one. It’s in a plastic pot with moss and it is damp. What should I do? Look forward to hearing from you. Regards, Bev L.“
Here’s a photograph of an overwatered phalaenopsis :
Orchids can become sick and even be killed when overwatered. Therefore, it is extremely important to determine whether improper watering is damaging your orchid. Don’t know if you are watering your orchid plant correctly? Check out my special Orchid Care and Maintenance post to learn how to water your orchid.
What are the signs of an overwatered orchid?
Pleated, soft, yellow leaves are a sign of overwatering. Your orchid may also suffer bud blast (all of the buds fall off before they open). When examined out of the pot, orchid roots may be soggy, mushy and black.
What should I do if my orchid has been overwatered?
If the damage on the roots in limited, you can simply repot your orchid in a clay pot and fresh orchid potting mix (bark based if possible) and adjust the frequency of your watering schedule—making sure to water only in the mornings. Don’t forget to adjust temperature and humidity levels if necessary.
On the other hand, if the damage of the roots is severe, you will need to remove the diseased portions of the roots with a sterilized blade and carefully repot the plant in a clay pot and bark potting mix (otherwise you rise losing your orchid.) I recommend you refer to Ryan’s “My orchid has been over/underwatered. Now what do I do?” section in his book Orchids Made Easy, for detailed information.
