Answer: Water them thoroughly the day before the move. When you dig them, take as much of the root system as you possibly can. Replant them immediately at the same depth as they grew before, water well to settle the soil, and mulch. Do not fertilize or prune this late in the season. Water as needed to keep the soil damp until it freezes. Later this fall, after freezing weather, add more mulch to about six inches deep over the root area. Next spring before they begin to grow for the season, gradually remove the excess mulch and trim the roses back to remove any winter damage (or by half, whichever is more) and make them somewhat symmetrical. You would also fertilize next spring. Water as needed next summer to keep the soil evenly moist (not sopping wet or saturated) just as you would for any new plant. Good luck!
