Like so many shrubs that can sprout again and again from their roots, lilacs can also get very old. There are specimens in numerous gardens that have been around for many decades and still sprout and bloom beautifully every year. In some parks there are even lilac trees that date back to the 19th century, when the flowering tree really became popular through new varieties.
How long can a lilac tree live?
Lilac trees can live 50 to 60 years if well cared for and in the right location. Care requirements include a full sun, airy location, permeable and dry soil, sufficient plant spacing and moderate pruning to rejuvenate and prevent diseases.
What makes a lilac grow old
It is not uncommon for a lilac tree to be 50 or 60 years old, but centuries-old lilac trees are. After all, there are many things that can ultimately bring down the generally robust tree. Above all, there are fungal infections to which lilacs are very susceptible, or the common lilac disease caused by a bacterium. In addition, the lifespan depends not only on the he alth of the lilac, but above all on its location and the care it receives.
Location and soil
Plant the lilac in a location that is as full of sun and airy as possible with permeable, rather dry and sandy soil. Compacted soils, such as those that are typical immediately after building a house due to the use of heavy construction machinery, as well as heavy clay soils are less comfortable for the lilac and should be improved.
Care
Not only the right location, but also the right care has an influence on the lifespan of the lilac. Specifically this means:
- Lilac should be kept dry rather than moist.
- Waterlogging leads to root rot and thus premature death.
- Shrub should still be watered during long dry periods, especially. a. when he is still young.
- For planted lilacs, one or two compost applications per year are sufficient.
- An airy location with sufficient planting distance keeps pests and pathogens away.
- React quickly if signs of illness appear.
- Prevention is even better: Regular spraying with field horsetail decoction as soon as it sprouts protects very well against a fungal infection.
Cutting
If you want the lilac to live as long as possible, you must not cut it back too much. It makes sense to clean out the bush every year after flowering and remove any outdated shoots. A thinning cut also ensures continuous rejuvenation.
Tip
On the other hand, if your lilac is very old and in danger of dying, you may be able to use it - but that doesn't always work! – save with a radical cut. However, you can only do this in winter.
