Blue rain, also called Wisteria, delights us with its wonderfully fragrant and beautiful flowers. To keep it that way, you have to cut wisteria properly.
But beware: If you don't cut wisteria regularly, you risk that it will start to proliferate like mad and that the number of flowers will decrease.
Cut wisteria twice
Wisteria is a real climbing artist and is therefore particularly suitable as a natural roof. Wisteria is one of the few plants that needs to be cut twice a year. In February or March you can already prune it to three buds. However, you should only do this with the young shoots. After the summer flowering, you must cut down all side shoots to up to 20 centimeters. Wisteria is very undemanding when it comes to pruning. It even tolerates a radical cure, because it keeps sprouting out of the thick branches.
Powerful Creeper
Since the plant will wrap itself around everything, be careful not to let it take over other plants' habitat or damage your home. Because the creeper has enormous strength and can even damage gutters. To prevent this from happening, you should always place climbing aids at a distance of at least one meter from the facades so that the wisteria has no chance of destroying the gutter or even moving the roof tiles.
The Wisteria has such tremendous power that it would even be able to bend the bars of a railing or even loosen them from their anchorage. It is therefore important that you always keep an eye on the development of the wisteria between the trellis and your house.
