Can I dig up tuberose tubers and bring in before they turn yellow?
My tuberose just started sending up bloom stalks, but the temp is going down to low 30 and upper 20. The leaves have not turned yellow yet. I don't have the room to put in sunny window, and don't know what to do.
Why don't you try digging it up and putting it into a pot so you can bring it in for the night, and set it back outside in the morning when it warms up a bit. Make it a large pot so you can include lots of roots. When it finishes blooming and starts to turn yellow, you can store the tubers as usual.
