Break the rules
Normally, we only advise gardeners to replant or move their roses in June when the roses are dormant. If the roses are not doing well, with very little new growth and flowers break the rules and do so now. Being at home you have the time to pamper them.
Prepare the new position first and if possible, make a raised bed, filled with organics (peanut shells, compost, shredded bark), that offers good drainage and nutrition. The roses easily send new roots into the spongy, soft soil.
The day before transplanting, water the roses very well. Trim the rose, making sure you leave enough leaves to shade the stems.
