Cutting instructions for dwarf lilacs - when and how to cut correctly

Brushing out stimulates re-flowering

The main flowering period of dwarf lilac is from May to June. This does not end this year's flower festival. A little tutoring with secateurs is enough to stimulate the distinctive ornamental wood to develop a second flower pile. At the end of June / beginning of July, cut back withered flower panicles to the next, easily recognizable bud approach.

Cut into shape after flowering

When the flowering time is coming to an end, the time window opens for a regulating shape cut on the dwarf lilac. Time is of the essence, because all the lilacs plant the buds for the next year's flowering period in the same year. How to cut with expertise:

  • First check the shrub for nesting birds to postpone the cut if necessary
  • Cut off wilted flowers beforehand to prevent self-sowing
  • Cut back excessively long branches sticking out of the shape
  • Choose a point of intersection a short distance from a pair of leaves or a bud

The very leisurely growth rate of 5 to 15 centimeters per year does not require extensive pruning to ensure that your dwarf lilac is in top form. This has the advantage that you can limit yourself to this year's increase and consequently act in accordance with the provisions of the Federal Nature Conservation Act.

Thinning out dwarf lilac in late winter

Older or rarely cut dwarf lilacs benefit from a clearing cut. Old, decaying branches are removed to make room for young wood. The pruning type is equally advantageous for a shrub and a tall stem crown. How to properly light a dwarf lavender:

  • The best time is from the end of January to the end of February
  • Do not cut in frost, rain and blazing winter sun
  • Cut frozen and kinked shoot tips back into healthy wood
  • Dwarf lilac shrub: cut dead branches back to 10 cm short cones
  • Dwarf lilac high trunks: Cut 2 to 3 of the oldest, thickest crown branches on astring
  • Do not prune healthy shoots because they have numerous flower buds

Before each cut, please weigh up whether this could result in an unsightly gap in the shrub or crown. This shortcoming can be circumvented by using the cutting technique of the derivative. Examine the branch concerned to see whether it is still signaling the will to live by a side shoot positioned further down. Use scissors or a folding saw (€ 17.70 on Amazon *) at the junction of young and old wood.


The very similar names of dwarf lilac and summer lilac mean that home gardeners can easily confuse them when it comes to pruning. Buddleia (Buddleja davidii) are pruned vigorously in late winter to encourage the growth of blossom wood. If you also cut your dwarf lilac (Syringa meyeri), you will destroy all the flower buds that all real lilac species already plant in the previous year.
