The flower of forsythia is always in line with the previous year. Therefore, the shrub is cut every spring in the spring after flowering.
Tightly densely dotted with yellow flowers, bushy and spreading, so we know and love the forsythia, this richly flowering shrub is also known to many garden lovers as gold bells or gold lilacs. Unfortunately, many forsythia sadly take care of themselves and offer a rather bleak sight.
With a targeted pruning you remove non-flowering branches and give the plant new strength, so that next spring the yellow splendor can fully unfold.
Pruning after flowering
One thing is for sure: it is not at the site if the forsythia does not bloom or grows too weak. The shrub is consistently easy to clean and can handle most soil and sunlight.
However, a regular pruning is necessary so that the abundance of flowers can develop. However, it is sufficient for stand-alone forsythia when the hedge trimmer is scheduled every two to three years. The so-called Auslichtungs- or maintenance cut ensures that the middle of the shrub is not too dense and leucorrhea.
Long, overhanging shoots that grow far beyond the crown are also shortened.
The flowers sit directly on the wood and are created in the previous year. However, old shoots lose much of their flowering after about three to four years. Remove these branches.
- The right time is right after flowering, as can be seen when the yellow petals wither and contract.
- Strongly branched branches also remove.
- Very old branches cut directly at the base. They avoid that the plant is overgrown. The young shoots get more power and form for the upcoming spring numerous flower approaches.
☛ Tip: If you carefully observe your forsythia during flowering and notice that some branches are not blooming, you can radically remove those branches. The forsythia tolerates a lot and next year will form new, lush shoots.Cutting back forsythia to another season?
