Eliminating Lilac Shrubs in the Garden: A Guide to Successful Removal of Lilac Bushes
In the world of gardening, dealing with old lilac bushes can be a challenging task. But fear not, as we've gathered some useful tips from master gardener and San Francisco Botanical Garden docent, Teo Spengler.
Firstly, it's important to understand that cutting down a lilac bush at ground level is merely a temporary solution. The plant will regrow from any piece of root section left in the ground, potentially leading to a new crop of lilacs.
As the roots grow along, they send up sucker shoots, each one of which can grow into a new bush. This means that if you don't remove the entire rootball, you might find yourself with an entire grove of lilac shrubs over time.
To remove the rootball, a few methods can be employed. Manual removal, cutting and pulling out roots, using smothering techniques with mulch or tarps, and controlled burning are all non-chemical methods. To start, tie a strap around the base of the lilac, put tension on it with a vehicle, then cut the roots on the other side.
For older, established plants, a tractor or truck may be needed to pull out the root system. But for younger plants, you might be able to pull out the roots by hand, after watering the ground around the plant thoroughly to help loosen the soil.
For organic alternatives to chemicals, consider contacting your local university extension service or talking with a local garden centre. They can provide advice tailored to your specific situation.
If manual removal is not possible, hiring a landscaper or someone with heavy equipment may be necessary. Always aim to avoid the use of chemicals whenever possible when removing old lilac bushes.
Lilac bushes reproduce not only by seeds but also by growing new plants from suckers. Shoots grow from the roots that grow parallel with the soil surface. So, be sure to remove all of these shoots to prevent regrowth.
In conclusion, removing old lilac bushes can be a complex task, but with patience, the right tools, and a bit of know-how, it's definitely achievable. Happy gardening!
