Q.How Do I Know If My Wisteria Plant Is Still Alive?
My plant lost all its leaves at the end of December. Is hot and sunny now in the UK. When will it grow its leaves again? How soon after winter does it bloom again? I’ve attached a photo of my plant, it’s about 6cm. Thank you ?

Is that a tiny leaf I see at the end of this stem? I suggest using some sterile scissors and clipping it off in the middle of that bend in the center. Give it some compost and some sunlight and see what it does.
If you scratch the stem with your fingernail and you see green underneath the surface, it is probably alive. Wisteria like soil that's slightly acidic.
