Dude depends on how much damage was done to the overall root system?,right now your plant is lacking water simply because most of the watering roots were left in the previouse hole lol,best thing I could say to do is try and foilage feed your plants with water as much as possible until roots once again develop,try soking the leaves and over all plant with water a couple of times a day,put garbage bag over plant to maintain moisture,it's alot of work I guess but it could be done,you almost have to treat your mature plant like you would a clone of a plant,giving it water through the leaves until the stem breaks forth with roots,keep it out of the sun for a few days shade it as much as possible,and remove alot of foilage(leaves) after all these leaves draw alot of water and in your case you don't have alot of water to to pass around,,,,,,,,,,,it may take may not,,,,it's worth a try I guess so late into the season may be worth it!.good luck............could you make a humidity dome big enough for the plant?,I thought grabage bag over plant after a good soaking!,try to come up with a idea to keep moisture in with the plant,but don't forget to take the bag off every now and then to allow fresh air in,,,try it,what do you have to lose?
