  • Keep the soil moist and the pot in a warm, sunny location.
  • After a few weeks, you should see new growth emerging from the stem.


The third method of propagating lilacs is called layering.

  • Choose a low growing branch on the lilac bush.
  • Gently bend the branch down to the ground and bury it in the soil.
  • Place a small rock or stake on top of the buried section to keep it in place.
  • Keep the soil moist and wait for roots to form.
  • After a few weeks, you should see new growth emerging from the buried section.
  • When the new growth is about 6 inches long, cut it free from the original bush and transplant it to a new location.

Now that you know these three methods of propagating lilacs, you can experiment with each one and see which works best for you. Whether you choose division, cuttings, or layering, you’ll be able to enjoy even more beautiful lilacs in your garden.

When To Propagate Lilacs

The sweet fragrance of lilacs can leave any nature lover spellbound, making it a delightful addition to any garden. If you’re looking to add more of these gorgeous flowers to your outdoor space, propagation is the answer. But, when is the right time to propagate lilacs?

Let’s find out.

Best Time For Each Propagation Method

There are different ways to propagate lilacs, each with their own best time to do so.

  • propagation via hardwood cuttings: late autumn or early winter, when the lilac plant is dormant, is the best time to take hardwood cuttings from the parent plant. This ensures the cuttings have sufficient stored energy to grow roots.
  • propagation via softwood cuttings: late spring or early summer is the ideal time to take softwood cuttings after the new growth appears. Make sure the cuttings are taken from healthy, disease-free trees that are actively growing.
  • propagation via air layering: the best time to air layer lilacs is during late spring or early summer when the plant is actively growing. Mid to late spring is also suitable if the plant has not yet began to grow.

Factors To Consider In Timing

The timing of propagation in lilacs depends on several factors.

  • plant maturity: it is essential to wait until your plant is mature enough before trying to propagate. Lilacs take a few years to establish, and it’s best to wait until they are at least three years old before attempting propagation.
  • environmental conditions: lilacs fare best in cooler temperatures, making spring and summer the ideal time to propagate. Late autumn and early winter, when the plant is dormant, are also suitable for hardwood cuttings since the cuttings can root during winter’s cool temperatures.
  • disease and pest pressure: when you propagate lilacs, you want to ensure that any cuttings you take are disease-free and pest-free. Keep an eye on your plants and wait for a few days where you don’t see any disease symptoms or pests before taking cuttings.

The timing of propagation in lilacs is crucial for the success of the process. Make sure to choose the right method and time it correctly to ensure your plants thrive.
