plantladylin said:I'm far from an orchid expert but I don't think Miracle Grow Potting mix would be the correct medium for any orchid unless it's a terrestrial type that grows in the ground. Moth Orchids are epiphytic by nature and require good air circulation around their roots to do well; heavy soil will suffocate the roots which may be the cause of your plants leaves yellowing.

Here's the American Orchid Society culture sheets for Moth Orchids (Phalaenopsis)"

We have a few very knowledgeable orchid growers on this site who will be able to offer good advice, @Ursula @BigBill

I'm using miracle grow orchid mix - not potting mix. I made sure not to make that mistake with orchids. It is a bark-based medium with barely any true soil. I also chose the terra cotta for extra aeration. I remember back in the day when people used to say they needed gravel and consistent moisture like a river! Poor orchids never stood a chance...
