Pruning overgrown shrubs can be a daunting task, but with the right techniques, it can be easily accomplished. When it comes to deciduous shrubs, one method of pruning is to cut them back to within 4 to 6 inches of the ground. This may seem drastic, but it can be highly beneficial for the shrub’s overall health and appearance.
By cutting the shrub back to such a low level, you are essentially rejuvenating it. This severe pruning stimulates the shrub to produce a large number of new shoots during the growing season. These new shoots will emerge from the base of the shrub and have the potential to grow into healthy, well-structured branches.
Timing is crucial when it comes to this type of pruning. It is best to do it in March or early April, before the shrub begins to actively grow for the season. This allows the plant to allocate its energy towards producing new shoots rather than supporting existing foliage. Additionally, pruning in early spring ensures that the shrub has sufficient time to recover and grow before the arrival of winter.
I have personally used this method to rejuvenate overgrown shrubs in my own garden. One particular shrub, a lilac, had become so overgrown that it was blocking sunlight from reaching other plants in the garden. I decided to take a leap of faith and cut it back to a few inches above the ground. To my surprise, within a few weeks, numerous new shoots emerged, and by summer, the shrub was thriving with fresh, vibrant growth.
While this method of pruning is effective, it is important to note that not all shrubs will respond well to such severe pruning. Some species may not have the ability to regenerate from such low levels, and others may take longer to recover. It is always a good idea to research the specific shrub you are working with to ensure it is suitable for this type of pruning.
To summarize, cutting back overgrown deciduous shrubs to within 4 to 6 inches of the ground in March or early April can be a great way to rejuvenate them. This severe pruning stimulates the growth of new shoots during the growing season, resulting in a healthier and more aesthetically pleasing shrub. However, it is essential to research the specific shrub and consider its ability to regenerate before employing this pruning method.
