I have 3 crocks of English ivy. I have them in our screened in porch (we live in Gainesville, Va). Can I just stop watering for the winter? Will they go dormant? Will they start to grow again in the spring?
I would cut back on the water, just enough to keep the soil from drying out completely.
They will go into a dormancy period.
If the temperatures should drop to the freezing level, make sure the pots are insulated in some manner so that the roots don't freeze.
