You can prune Bloomerang lilacs, but it is important to do so at the right time to avoid removing the spring flower buds. The best time to prune Bloomerang lilac is immediately after its spring bloom. This allows the plant to recover and produce new growth for the next year’s bloom.
Pruning in fall, winter, or early spring should be avoided as it can remove the flower buds and diminish the potential for a beautiful spring display. It is crucial to understand that Bloomerang lilacs bloom on old wood, meaning that the flower buds are formed on the previous year’s growth. Pruning too early can remove these buds and result in a lack of flowers.
When it comes to the actual pruning process, it is important to be mindful of the overall shape and size of the lilac. Start by removing any dead or damaged branches, as well as any crossing or rubbing branches. This will help improve the overall health and appearance of the plant.
Next, you can selectively prune to shape the lilac and maintain its desired size. It is best to prune back to a lateral branch or bud, making clean cuts just above the node. Avoid leaving stubs as they can lead to disease or insect infestations.
If your Bloomerang lilac has become overgrown or you want to rejuvenate it, you can perform more severe pruning. This involves cutting the entire plant back to about one-third of its overall size. While this may seem drastic, it can often encourage new growth and result in a more compact and vigorous plant.
In terms of tools, it is recommended to use sharp bypass pruners or loppers for smaller branches, and a pruning saw for larger ones. Make sure to disinfect your tools before and after pruning to prevent the spread of disease.
It is worth mentioning that while pruning can help maintain the shape and size of a Bloomerang lilac, it is not necessary for it to rebloom. These lilacs are known for their ability to produce multiple flushes of blooms throughout the summer, without the need for extensive pruning.
In my personal experience, I have successfully pruned Bloomerang lilacs in my garden. I followed the recommended guidelines of pruning immediately after the spring bloom and avoided pruning in fall or winter. By selectively removing dead or crossing branches and shaping the lilac, I was able to maintain its overall health and appearance. The lilac continued to rebloom throughout the summer, providing a delightful fragrance and beautiful flowers.
To summarize, you can prune Bloomerang lilacs, but it is crucial to do so immediately after the spring bloom. Pruning in fall, winter, or early spring should be avoided to prevent the removal of flower buds. Proper pruning techniques, such as removing dead or crossing branches and shaping the lilac, can help maintain its health and appearance. However, it is important to note that pruning is not necessary for Bloomerang lilacs to rebloom.
