Answer: Aunt Dee is a Japanese wisteria (W. floribunda) with a small lavender flower. (W. sinensis is Chinese wisteria.) It blooms in early summer. It needs moist, but well-drained soil and full sun. It is a fast grower, up to 10 feet in one season. Wisterias usually don't need fertilizer. Layer compost around the base and as it decomposes it will add nutrients to the soil. Prune after bloom, cutting the new growth back to three buds. This will encourage the development of new flowering wood. Wisteria doesn't like to have its roots disturbed, but if you must move it, do so in the late fall when the plant is dormant or nearly dormant (to reduce stress). Dig as much of the rootmass up as you can and set it in the new hole so that it will be at the same soil level as it was growing before. I expect that after only 2 years in its current location that you'll find the roots in the top 12" of soil, extending out about 2' on all sides. I'd start digging about 18" from the main stems of the plant, digging down to about 12". You may only end up with 12" by 12" of rootmass for your plant, but it may be larger, so dig carefully.
Best wishes with the move!
