To properly prune old glory lilacs, there are a few key steps to follow. First, it is important to prune less than 1/3 of all branches. This ensures that the plant maintains its shape and does not become too sparse. By pruning less than a third of the branches, you will encourage new growth and prevent the plant from becoming too overcrowded.
Next, it is recommended to keep 8-12 branches of different ages with a diameter of 2.5 to 5 cm. This range ensures that you are keeping a good variety of branches that will produce healthy blooms. By keeping branches of different ages, you are promoting a balanced growth pattern and preventing the plant from becoming too top-heavy.
Additionally, it is important to maintain the plant at a height of 2.5 m or less. This height ensures that the plant remains manageable and does not become too difficult to maintain or prune. By regularly trimming the plant to this height, you are promoting a compact and healthy growth habit.
When it comes to removing branches, it is best to focus on old, dead, and diseased branches. These branches can be cut from the base of the plant after blooming at the end of winter or late spring. By removing these branches, you are improving the overall health and appearance of the plant.
Furthermore, it is important to address any seedlings that may be growing from the roots of the plant. Most seedlings should be removed, as they can compete with the main plant for resources and potentially weaken its growth. By removing these seedlings, you are ensuring that the main plant receives the necessary nutrients and can thrive.
In terms of technique, it is best to make clean cuts at a slight angle just above a bud or lateral branch. This will promote proper healing and encourage new growth. It is also important to use sharp and clean pruning tools to prevent any damage or disease transmission.
In my personal experience, I have found that regular pruning of old glory lilacs is essential for maintaining their health and beauty. By following these pruning guidelines, I have been able to achieve a well-shaped and vibrant plant. It is important to be patient and take your time when pruning, as rushing can lead to mistakes or over-pruning.
To summarize, pruning old glory lilacs involves pruning less than 1/3 of branches, keeping 8-12 branches of different ages with a diameter of 2.5 to 5 cm, maintaining the plant at a height of 2.5 m or less, removing old, dead, and diseased branches, and addressing any seedlings growing from the roots. By following these steps and using proper technique, you can ensure the health and beauty of your old glory lilacs.
