Took awhile for it to get established. Been a bad weather spring for most of my garden. But it’s rooted well and all buds now opening and even done early fruit setting in! I’m really excited to trellis it up alongside my garage!

Bought at end-of-season sale and they were healthy. Leafed out within about 14 days and are looking good.
