I bought two kalanchoes about a month ago and planted them in a pot. They were out under the sun from 8 am to 4 pm when the maximum temperature varied around 27-30 degrees. The pot does not have drainage system, hence I watered it when the top soil dried out like this.
Recently I noticed the leaves turning reddish and then yellow. They are no more green at all. I thought it was sun burnt, so I placed it in the shadows, but things didn't improve. The yellow leaves are not papery, not fleshy either and wilted.
Today I dug out the soil to see if excess water was accumulated in the pot or if there was a root rot. No accumulated water, roots I couldn't see. The soil was something like lightly moist, dry-ish, could be broken into small pieces with the hands.
Now, I have planted it again with some vermi-compost at the bottom, then some soil(clayey), then again compost. Is it okay?
Is my plant dying? Is there anything that can be done to save it from this point?
