If you love lilacs, growing them from cuttings is an easy and rewarding way to expand your garden for free.
Instead of buying new plants, you can take cuttings from an existing lilac bush and grow your own. With the right timing and care, those cuttings can turn into healthy, blooming plants.

Choosing the Right Cuttings
Not all lilac cuttings will root successfully, so it’s important to start with healthy stems.
Look for:
- Green, flexible stems (not woody)
- About 4–6 inches long
- At least 2 pairs of healthy leaves
- No signs of pests or disease
Softwood cuttings taken from common lilacs (Syringa vulgaris) are usually the easiest to grow.
Best Time to Take Cuttings
The best time to take lilac cuttings is late spring to early summer.
At this stage, the stems are still soft and flexible, which gives them the best chance of rooting.
- Take cuttings in the morning if possible
- Use clean, sharp pruning shears
- Cut just below a leaf node
How to Prepare the Cuttings
Before planting, prepare your cuttings properly:
- Remove leaves from the bottom half
- Leave 1–2 sets of leaves at the top
- Dip the cut end in rooting hormone (optional but helpful)
This helps the plant focus energy on root growth.
How to Root Lilac Cuttings
You can root lilac cuttings in either soil or water.
Option 1: Rooting in Soil (Best Method)
- Use a well-draining mix (potting soil + perlite)
- Insert the cutting into moist soil
- Cover with a plastic bag or humidity dome
Option 2: Rooting in Water
- Place cuttings in a jar of water
- Change water every few days
- Transplant once roots form
Soil rooting tends to be more reliable for long-term growth.
Planting the Cuttings
Once roots begin to develop, it’s time to plant your cuttings.
- Use a small container with drainage holes
- Fill with well-draining soil
- Plant gently and firm the soil around the stem

Young lilac plants need a little extra care at first.
- Keep soil moist but not soggy
- Provide bright, indirect light
- Maintain humidity with a cover or misting
After about 6–8 weeks, roots should be established.
When to Transplant
Once your cuttings have:
- Strong roots
- New leaf growth
You can move them to larger pots or into your garden.
Choose a sunny location with good drainage.
