Do you have spring blooming bushes that are looking a little weary? Prune spring blooming lilacs, spirea, and viburnums immediately after they are done blooming, even though you might not see the buds they are forming on the branches for next year. Trim out larger branches from the middle of the shrub to allow for ventilation and leave the strong, healthy new stalks. By pruning a little each year, you will maintain the shape, size, and vigor of the shrub.
