This upright shrub has strong branches and brightens up your garden in spring with a splendor of yellow flowers. Leaves appear on the bush only after flowering. A forsythia must be pruned every year to continue to flower profusely. People often forget to do this in time.
The forsythia plants
The best time to plant this shrub is in the autumn, then the plant has until winter to root well. The forsythia is a strong shrub that only needs water in extreme heat and drought. Think of a period of 15-20 days. This shrub is a true lover of the sun and requires at least six hours a day in the spring and summer. The forsythia is also easy to take cuttings. Place a few young shoots in a pot of soil and if they take root, they will root within a few weeks. A potential problem with the shrub is that it is prone to rot, which is caused by a bacteria. The leaves then turn brown and eventually even black. To save the forsythia, cut it back until you reach healthy wood.
When and how to prune forsythia?
It is a difficult job to prune a forsythia properly and if you are not sure, it is wise to watch an instructional video.
You should prune the forsythia after flowering in the spring. Flowering takes place on biennial wood. If you prune after flowering, the shrub still has enough time to form new branches. Pruning proceeds as follows:
Look for a strong spur that is growing outwards near the spent branches.
Using sharp pruning shears, cut the rest of the branch diagonally, just above the spur.
Prune a number of old branches every year to just above the ground.
To get a richly flowering shrub the following year, you should leave about 3 to 5 strong and healthy branches.
Cut away dead wood and weak, thin side branches. These only cost the bush unnecessary energy
