What is the expected service life? (Syringa)

What makes a lilac grow old

An age of 50 or 60 years is not uncommon for a lilac tree, but centuries-old lilac trees are. After all, there are many things that can ultimately bring down this robust wood. Above all 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 health of the lilac, but above all on its location and the care it is given.

Location and soil

Plant the lilac in a location that is as full sun and airy as possible Location with well drained, rather dry and sandy soil. Compacted soils, such as those that are heavier when a house is built, for example Construction machines are typical, as well as heavy clay soils, the lilacs are less comfortable and should be improved will.

care

Not just the right location, but also the right one care has an impact on the lifespan of the lilac. Specifically, this means:

• Lilacs should be kept dry rather than damp.
• Waterlogging leads to root rot and thus to premature death.
• The shrub should still be watered in long dry periods, v. a. when he's young.
• If the lilacs are planted, one to two compost applications per year are sufficient.
• An airy location with sufficient plant spacing keeps pests and pathogens away.
• React quickly when signs of illness appear.
• Prevention is even better: Regular spraying of field horsetail brew from budding provides excellent protection against fungal infections.

Cut

If you want the lilac to live as long as possible, you shouldn't prune it back too much. It makes sense to remove the shrub every year Clean up after flowering and remove overaged shoots. Also a Clearance cut ensures continuous rejuvenation.
