Answer: If I were you, I'd start with a fresh new currant bush. Once they've grown that large, they're hard to transplant. Generally, a plant's root system matches the size of the crown, so it may be more trouble than it's worth just to dig the new planting hole! Since you're nearly through the 3-year renovation, maybe you'll want to take it through one more year before you decide.
Currants lose their leaves early in the more southern reaches of their range, so if you've had a spell of hot, dry weather, it may be the reason for the sad looking leaves.
Though they aren't heavy feeders, currants do appreciate an annual addition of organic matter (compost, aged manure), a few pounds of soybean meal and a cup of greensand. If you want to check out some good varieties, request a catalog from Miller Nurseries, 5060 West Lake Rd., Canandaigua, NY 14424, ph# 800/836-9630). Enjoy!
