If the flowering shrubs are neglected in the spring or summer, they may need extensive trimming and pruning in order to renew or rejuvenate the plants. The ideal time for major plant rejuvenation on overgrown shrubs is during the late winter months or the early spring months prior to the plant’s leaf out phase.
If you did heavy pruning in the latter part of winter or early period of spring, it will eliminate or reduce your floral display for just a few years. However, restoring your shrubs back to health is more important. Never try to prune your deciduous shrubs in the middle of summer. Try to do so in August, encouraging a delayed flush of growth.
Whether you have needle bearing or broadleaf evergreen shrubs, you should try to prune after new growth emerges in the springtime. After all, it is primarily new growth that provides an opportunity for the shaping of your hedges, assuming that you were already making sure that the hedges were maintained all this time. If the branches to be trimmed are sufficiently small, you can use a shearer with a hedger. Prior to when the new growth starts for your evergreen shrubs like yew or juniper, pruning is actually best performed in the latter weeks of March to the early weeks of April. Try to avoid doing so in the fall. Your evergreen shrubs could become injured by the colder temperatures when they were recently pruned.
For the upper section of modern roses, low winter temperature exposure or drastic changes in temperature will kill the plants during the winter if pruned during the season prior. Therefore, the dead wood should be pruned in the late summer to keep things healthy. Any roses that bloom throughout the entire summer should be pruned in the month of March to early April, with minor pruning throughout the summer to maintain shape and health.
