Lilac suckers, also known as lilac shoots, are a much faster way to start new lilacs rather than cuttings. Spring is a great time to do this as the soil is moist and easy to dig and the suckers are really growing. Want to get a clone of your Grandma’s lilacs? This is for you!
Every May I love taking my morning coffee outside to sit on my steps under my front arbor. My neighbor has a large lilac that blooms prolifically and perfumes the morning air.
I sit, sip and breathe in the sweet scent of Spring and feel my stresses melt away. I knew I wanted a lilac (or ten) so I asked if I could dig up some of the suckers.
Today I am going to show you how you can propagate lilacs from suckers and get more sweet smelling lilacs in your garden. You’re going to love this one!
Why Propagate Lilacs from Suckers or Shoots
This method to propagate lilacs from suckers is easy and you get a new plant which blooms much faster than from cuttings.
Be sure to watch the video at the end. I was able to convince my neighbor to let me dig up a sucker of the Lilac you see in the top photo!
What are Lilac Suckers
Suckers are shoots that grow from around the Lilac base. Some feel they can be a menace but most folks just cut them off with a mower or weed wacker to keep them in check.
This is a white Lilac in a friends yard. She said I could come dig up all the suckers or shoots I wanted. Now it does take a good sharp shovel and a bit of muscle but it is not hard.
Find some suckers that are far enough away from the parent bush to get in there with a shovel and have some leverage. This soil was super compacted so I didn’t get as much root as I would prefer yet it still worked.
How to Dig Lilac Suckers
With a good push with your foot shove the shovel straight down and cut through the sucker root. You will have to put your weight into it, slicing through can be tough. (having a sharp shovel is key)
Do that all around the sucker and pop it up out of the ground, hoping you have a good portion of root.
Dig up as many as you can. You may lose a few but so far I have had 100% success rate with this method. If you dig up plenty you can be assured to have one survive and if all survive you can always give away what you don’t want to keep.
I have a bucket of water nearby and I put them right in it. Keeping them moist helps to lessen the shock.
I had something come up and could not get to them right away but they seemed to do fine in the water for a few days. They were kept in the greenhouse but a shady spot in the yard will work just fine too.
Potting the Lilac Suckers
With some I cut the large roots back so it is easier to fit them in the pots, the smaller roots will be fine to get started.
Then I fill some gallon pots with potting soil halfway then plop in a sucker before filling the pot the rest of the way with soil.
I had to use the larger diameter pot for this mass of roots.
So far they are all looking okay, I did this a week ago and I have been keeping a close eye on them.
Propagating Lilacs in pots
A couple weeks ago I noticed that the starts I had rooted from cuttings had suckers coming up in the pots. So I decided to divide those too. It is much easier as the roots are not that big yet.
I popped the Lilac out of the pot and was pleased with the healthy root mass. They really do need to be potted up or divided and I opted for dividing, I am not sure where I want to plant them yet.
I grab my garden knife and slice through the entire root mass between the center rooted cutting and the side shoots, which are the suckers.
Now repot them up in separate pots with fresh potting soil.
You can see the mother plant and two daughter plants all in their very own pots.
I did this a few weeks ago and they are growing strong and healthy. Not even a bit of droop from shock.
Transplanting Lilac Shoots
You do not have to put your freshly dug suckers or shoots into pots. You can plant them directly into the ground.
Just dig a hole deep enough, loosen up the soil some by digging around with your shovel. Place your freshly dug lilac sucker or shoot into the hole and fill back with the loose soil. Firm it in with your foot, not too much.
Keep your fresh planted lilac watered until it is established. This is best done in Spring before the temperatures get too hot so the roots can start to get growing and able to bring up water. Keep close watch on it for a few months.
And that is how you propagate lilacs from suckers. Lilac propagation is how you get a lilac just like Grandma’s.
I wish you a sweet smelling garden!
