- Though lilacs hold much beauty, their sprawling and complex root systems may interfere with other plants and flowers. They may also suffer from blights and infestations which eventually overtake entire shrubs, or their blossoms may attract too many bees to the garden.
Attempting to completely remove lilacs from a yard or garden can be frustrating; rogue roots of this extremely hardy bush often persist even after being cut down and dug up, blossoming unexpectedly the following spring. Merely cutting down a lilac bush will only cause it to grow back stronger than before.
Fire can be used to kill persistent lilacs. If you're trying to burn shrubbery stumps or roots, use extreme caution and check with local authorities regarding lawn burning. You may not be permitted to burn yard waste on your property. Also, bear in mind that it may take more than one burning to completely eradicate the root systems. When conducting controlled burns, always have a fire extinguisher and water supply on hand. - Not interested in getting rid of your lilacs? Burning can be beneficial to lilacs suffering from infestations or blight. Prune the affected areas, then use a match, cigarette lighter or other easily-controlled small flame to cauterize the cut. Burn the infected branches as well to avoid contaminating your other plants during disposal.
- Lilac is a commonly-used firewood in building a campfire or for cooking. Thin lilac branches make outstanding kindling, emitting a light and fragrant smoke which can complement seafood and other mild dishes. Thicker branches create a strong, clear flame and a fragrant woodsmoke.
Lilac wood can also be used safely in wood-burning indoor fireplaces, lending a light fragrance to the home. Before using lilac or any other wood in your fireplace, be sure it is designed to burn wood.
