Choosing the Right Time to Propagate Lilac

One of the most critical factors in successfully propagating lilacs is choosing the right time to take cuttings. Lilacs are deciduous shrubs that bloom in the spring, and timing is everything when it comes to propagating them. If you take cuttings at the wrong time, they may not develop roots or may not survive the transplant process. Here are some tips for choosing the perfect time to propagate lilacs:


The best time to take lilac cuttings is in late spring or early summer, right after the shrub has finished blooming. This is the time when the shrub is producing new growth, and the stems are still soft and flexible. If you wait too long, the stems will become woody, and it will be much harder to get them to root.

It’s also important to take cuttings when the weather is mild and stable. Avoid taking cuttings on very hot or very cold days, as extreme temperatures can stress the plant and make it harder for the cuttings to root. Ideally, choose a day when the temperature is between 60 and 70 degrees Fahrenheit and when there isn’t too much wind or rain.


When you’re ready to take cuttings, make sure you have all the necessary tools on hand. You’ll need a sharp pair of pruning shears or scissors, a clean container filled with water, and a plastic bag or plastic wrap to cover the cuttings.


Choose a healthy lilac plant to take cuttings from. Look for a shrub that is at least three years old and has plenty of new growth. Avoid taking cuttings from a plant that is stressed or diseased, as this can affect the success of the propagation process.


When taking cuttings, make sure you choose stems that are at least six inches long and have several sets of leaves. Cut the stem at an angle, just below a set of leaves, and remove any flowers or buds. Dip the cutting into hormone powder to encourage root growth, and then place it in water to keep it hydrated.

By following these tips, you can choose the perfect time to propagate lilacs and increase your chances of success. Remember that lilacs are hardy shrubs that can withstand some stress, but it’s important to take care when taking cuttings and to provide them with the right conditions for growth. With a little patience and effort, you can propagate your own lilacs and enjoy their beautiful blooms for years to come.
