Did You Know?
1. Lilacs can be easily propagated by a method called “layering.” This involves bending a low branch to the ground, making a small incision in the bark, and covering it with soil until it develops roots.
2. Did you know that certain lilac varieties have been known to live for more than 200 years? The oldest known lilac tree is believed to be over 230 years old and can be found in New Hampshire, United States.
3. Despite the common lilac’s reputation for being a spring-blooming plant, there are a few varieties that actually bloom twice a year! These cultivars can produce a second flush of flowers in late summer or early fall.
4. It’s a little-known fact that even though lilacs are admired for their delightful fragrance, not all lilac flowers have a pleasant scent. Some varieties produce blooms that are odorless or even have a slightly unpleasant smell.
5. Lilacs have their own symbolic meanings in various cultures. For instance, in the language of flowers, lilacs represent beauty, youthful innocence, and confidence, while certain colors of lilacs, such as white, are associated with purity and spirituality.
Propagating Lilacs: Cuttings, Suckers, and Seed
Lilacs, known for their vibrant and fragrant blooms, can be propagated through different methods – cuttings, suckers, and seeds. Although each approach comes with its own advantages and challenges, propagating lilacs from cuttings or suckers is generally considered more feasible than from seed.
To successfully root lilac cuttings, it is essential to take them during the spring and early summer when the plants are actively growing. This timeframe coincides with the ideal pruning time after blooming, ensuring that the cuttings are taken from tender new growth that is more likely to root successfully.
When taking cuttings, several factors should be considered for optimal results. Firstly, it is crucial to select the right time, which is late spring and early summer when the plant’s growth is most active. Additionally, choose stems that are healthy and free from disease or pests.
Using the correct tools and compost is also important. It is advisable to clean and sharpen pruning shears before and after use to ensure a clean cut. Blunt tools can crush the stem, making it more challenging for the cutting to root. For planting the cuttings, it is recommended to use well-draining, sterile potting mix to create an ideal rooting environment.
Best Time to Take Lilac Cuttings
The best time to take lilac cuttings is during the summer when the plant’s growth is most active. This period corresponds with the end of the lilac blooming season and is also suitable for pruning. By taking cuttings during this time, you can benefit from the plant’s natural vigor, increasing the chances of successful rooting.
When selecting stems for cuttings, it is crucial to choose softwood stem sections that are slightly matured. These sections, usually 4-6 inches long, provide the ideal balance between tender growth and maturity. The bottom half of the cutting should have its leaves removed, leaving only 2-3 sets of leaves at the top.
Before planting the cutting, it is recommended to make a clean cut at a 45-degree angle just below a leaf node. This angled cut exposes more surface area for rooting. To further enhance the chances of successful rooting, the cut end of the cutting can be dipped in a rooting hormone before planting it in the potting mix.
- Choose softwood stem sections that are slightly matured, around 4-6 inches long.
- Remove leaves from the bottom half of the cutting, leaving 2-3 sets of leaves at the top.
- Make a clean cut at a 45-degree angle just below a leaf node.
- Dip the cut end of the cutting in a rooting hormone before planting it in the potting mix.
Step-By-Step Guide to Propagating Lilacs From Cuttings
To propagate lilacs from cuttings, follow these simple steps:
- Select healthy stems with no signs of disease or pests.
- Cut 4-6 inches of softwood stem that is slightly matured.
- Remove the leaves from the lower half of the cutting, leaving only 2-3 sets of leaves at the top.
- Make a clean cut at a 45-degree angle just below a leaf node.
- Dip the cut end of the cutting in a rooting hormone.
- Plant the cutting about two inches deep into well-draining, sterile potting mix.
- Cover the container with a plastic bag or plastic dome to maintain high humidity levels.
- Place the container in a location with bright, indirect light and keep the soil consistently moist.
- It can take 4-6 weeks for the lilac cuttings to root.
- Transplant the cutting in a full sun or partial shade spot in well-drained and slightly alkaline soil.
- Water the plant well after transplanting and keep it consistently moist.
- It is recommended to wait until late fall before transplanting lilacs grown from cuttings during their active growing season.
Propagating Lilacs From Suckers: How and When
Lilacs can be propagated through suckers that grow around the base of the plant’s trunk. Spring is the best time to propagate lilacs from suckers, as this is when new growth is emerging. Use a sharp shovel or garden knife to carefully dig around the suckers, preserving their roots. Once removed, these suckers can be planted in a new location or potted with well-draining compost.
Propagating Lilacs From Seed: Tips and Considerations
Propagation of Lilacs from Seed: A Guide for Gardeners
Lilacs are commonly propagated from cuttings and suckers, which is generally more reliable. However, it is possible to grow lilacs from seed. It is important to note, though, that only non-hybrid varieties will produce true replicas of the parent plant.
To propagate lilacs from seed, a process of stratification is necessary. This involves soaking the seeds for 24 hours and then refrigerating them for two months before sowing them in seed compost. The germination process requires temperatures of approximately 70˚F, which can be achieved by using a heated propagator or heat mat.
Once the seeds have been sown, germination should occur in about one month. The seedlings need to be nurtured indoors until they are strong enough to be planted outside, typically after the last frosts. It is important to keep in mind that propagating lilacs from seed can introduce genetic variability, unlike cuttings and suckers which produce clones of the parent plant.
the propagation of lilacs offers multiple methods for gardeners to expand their collection. Taking cuttings and propagating from suckers are the most reliable techniques, while growing from seed can introduce some variability. By following the proper techniques and taking advantage of the plant’s natural growth cycle, gardeners can successfully propagate lilacs and enjoy their beauty in various parts of their garden.
- Stratification is needed when propagating lilacs from seed.

Frequently Asked Questions
Can you propagate lilac from a cutting?
Yes, lilacs can definitely be propagated from cuttings. The ideal time for this process would be in the spring or early summer when the plants are in their active growth phase. It is essential to ensure that you time the cuttings correctly to increase the chances of successful propagation. Taking softwood cuttings at the right time allows the lilac plants to establish root systems and develop into new plants.
Do lilac trees multiply?
Yes, lilac trees have the potential to multiply. They typically propagate through a process called suckering, where new growth emerges from the roots, creating additional lilac shrubs. By planting various lilac species and hybrids, you can not only prolong the blooming period but also increase the number of lilac trees in your garden. This natural multiplication allows for an abundant display of fragrant flowers, enhancing the beauty and scent of your outdoor space throughout the spring and into early summer.
Can you dig up a lilac bush and replant it?
Yes, it is possible to dig up and replant a lilac bush. While the ideal time for transplanting is before it leafs out, lilacs have shown some tolerance for being moved at other times. The University of British Columbia Botanical Garden discussion forum suggests that transplanting during dormancy is a good option. Remember to carefully dig around the root ball, place it in its new location, and ensure proper watering and care for the lilac bush to adjust to its new environment successfully. It is always helpful to monitor the plant closely and provide it with the necessary nutrients and conditions for healthy growth.
Will lilacs root in water?
While it may be tempting to try rooting lilacs in water, it is generally not advised. Lilacs tend to have a harder time developing roots in water compared to other plants. However, if you do decide to experiment, it is crucial to use a clear or amber glass or jar and ensure that the stem is only submerged in water by 1 to 2 inches (3-5 cm) to avoid excessive moisture.
