When it comes to the blooming pattern of the Korean spice viburnum, it is important to understand that this particular species blooms on old wood. This means that the flower buds for the upcoming spring are formed on the previous year’s growth.
Personally, I have had the pleasure of growing Korean spice viburnums in my own garden, and I have learned through experience that pruning these plants in late summer or fall can greatly impact their flowering potential for the following year.
During my early years of gardening, I made the mistake of pruning my Korean spice viburnums in late summer, thinking it would help shape the plants and promote healthier growth. However, I soon noticed that the following spring, my viburnums produced very few, if any, flowers. This was a disappointing realization, as the beautiful fragrance and delicate blooms are one of the main reasons I chose to grow this particular species.
After some research and consulting with fellow gardeners, I discovered that pruning the Korean spice viburnum in late summer or fall removes the flower buds that have already formed on the old wood. This explained the lack of blooms the following spring.
To avoid this mistake in the future, I have adjusted my pruning schedule for the Korean spice viburnum. I now make sure to prune these plants immediately after they finish flowering in the spring. This timing allows me to remove any dead or damaged wood, as well as shape the plant if needed, without interfering with the formation of flower buds for the upcoming year.
It is important to note that not all viburnums have the same blooming pattern as the Korean spice viburnum. Some varieties, such as the arrowwood viburnum, bloom on new wood. This means that pruning these viburnums in late summer or fall will not affect their flowering potential for the following year.
The Korean spice viburnum blooms on old wood, and pruning these plants late in the summer or fall can remove the flower buds for the upcoming spring. To ensure abundant blooms, it is best to prune this species immediately after flowering in the spring. This personal experience has taught me the importance of understanding the blooming patterns of different plants and adjusting my pruning practices accordingly.
