Q.why won’t my weeping cherry get taller
I’ve had a weeping cherry tree for a few years. The limbs are strong and long but the trunk just isn’t getting taller. The limbs are dragging the ground. I don’t know if this thing is going to grow or not. The trunk also looks like it is branched out like limbs, instead of one trunk? When it was just a twig, rabbits chewed it off so I don’t know if that has anything to do with it. Does it have a chance or should I start over?

The rabbit may have destroyed the graft. At a minimum, it ruined the central trunk and spurred sprouting from below the graft called suckers. Read the following article and decide whether you want to try to train what is left or start over. https://www.gardeningknowhow.com/ornamental/trees/weeping-cherry/cherry-tree-no-longer-weeps.htm
