Just this month I purchased 5 calla lilies in the patio pots for my patio. Due to our cold temps, I have been keeping them indoors and only put them out during warm day hours. My problem is 3 out of the 5 now have developed a problem of leaves and flowers tipping over; and when I touch them, they come out as rotten. The bottoms seem to be rotting out and are slowing spreading and dying. In one I poked my finger down in dirt and there was a mass of jelly-like substance. Do they all have something in the dirt from the company that is killing them? What can I do, as they are too expensive to lose.
I got a calla lily plant about 3 weeks ago. It looks like the flowers are beginning to die off. I know they need a ‘dormant’ period. My question is: Is there a certain time of the year they should be dormant? With this being summer, it is concerning me.
Instead of digging up and storing the roots, can I just bring in the potted plant and store it in a dark place while I’m gone during the winter months? I’m usually gone for 6 months, so should I begin watering it and set it outside when I return?
