How to prune currants? What is done in winter is a renewal pruning thanks to which the plant, during the following seasons, will produce more fruit. If you are wondering why your currant plant bears little fruit, the fault may be linked to incorrect pruning.
Cut one or two branches, at the level of the stump (therefore at the base), the oldest ones that are now over 5 years old. Go to shorten even the excessively long shoots and cut the dry branches, broken or damaged by the wind.
These cuts are used to avoid the aging of the foliage. If, every year, one or two very old (five-year-old) clumps are severed, you will find yourself, within a few years, with a completely renewed plant.
Which scissors to use
Let's talk about pruning shears. Which to use to prune shrub plants such as currants, blueberries, gooseberries, red raspberries ... but also blackberry and rose brambles?
