Pruning your weeping cherry into the shape of a mushroom is not difficult. By following standard pruning procedure and pruning the weeping branches higher, you can create a mushroom shape in your weeping cherry tree. For cherry trees, you should prune your tree in late winter or early spring before the buds have begun to swell.
Decide on the height above the ground for your mushroom shaped weeping cherry. Measure the distance with a tape measure.
Remove any dead wood or branches from the tree. Dead wood and branches stress the tree and have a negative impact on living wood. Use a pair of sharp pruning shears on branches the size of a pencil or smaller. Use a pruning saw on larger branches.
Prune away any branches that cross. Crossing branches can rub against each other. That rubbing can damage the bark and create a disease vector.
Trim your weeping branches to the desired height above ground by clipping them with a pair of sharp pruning shears just below a leaf or bud.
