Winter watering of container roses.
Okay I am having a hard time wrapping my head around watering potted roses during the winter in my zone. Hopefully somebody can enlighten me.
I can understand watering in zones where the pot will not be totally frozen all winter or maybe won't freeze thoroughly, but here they are going to be ice cubes from now till march. Last week I lightly watered my pots and while the soil absorbed a slight amount the rest froze on the top. So my question is what is adding more water going to do for the rest of the winter other than add ice?
I have also heard comments that the roses get water from the soil when they are planted in the ground but within a few weeks we will have over 2' of frost and average 3-4' every winter. Those roses, too, will be ice cubes until March.
I can't figure out what I am missing.
