The bloom of forsythia is always on the previous year's shoots. Therefore, the shrub should be cut every year in spring after flowering.Forsythia basically bloom on the shoots of the previous year. Therefore a pruning is necessary in spring after the pile.
We know and love forsythia (forsythia), strewn with yellow flowers, bushy and expansive growing. This flowering shrub is known to many garden fans as gold bell or lilac. Unfortunately, many forsythias worry sadly and offer a rather bleak sight.
With a targeted pruning, you can remove non-flowering branches and give the plant new strength so that the yellow splendor can fully develop in the spring.
Pruning after flowering
First of all: It is not due to the location if the forsythia does not bloom or blooms too weakly. The shrub is easy to care for throughout and can cope with most soils and any sunlight.
However, regular pruning is necessary so that the abundance of flowers can develop. However, for single forsythia, it is sufficient if the hedge trimmer is used every two to three years. The so-called clearing or conservation cut ensures that the middle of the shrub does not become too dense and woodlessly wooded.
Long, overhanging shoots that grow far beyond the crown are also shortened.
The flowers sit directly on the wood and were created last year. However, old shoots lose their flowering strength after about three to four years. You remove these branches.
- The right time is immediately after flowering, recognizable when the yellow petals wither and contract.
- You also remove heavily branched branches.
- Cut very old branches right at the base. This will prevent the plant from becoming old. The young shoots are given more strength and are training numerous flower approaches for the coming spring.
☛ Tip: If you observe your forsythia carefully during the flowering period and find that individual branches do not have any flowers at all, you can radically remove these branches. The forsythia tolerates a lot and will develop new, lush shoots next year.Cut back forsythia at a different time of year?
Did you miss the cut in spring? Don't worry, the plants don't mind cutting back in early summer. And in this case you can even better recognize which young shoots have newly developed.
Forsythia planted as a hedge is also best cut back in May or June. For dense growth and more flowers, it is important that the existing branches and the new branches are in the correct ratio.
Even in autumn and winter you can still use the scissors: The season is ideal for the rejuvenation cut, in which you specifically remove old wood.At a glance: Bring forsythia to bloom
