Leave the purple loosestrife to its own devices
The simplest way of propagating a purple loosestrife is to let nature run free. The ornamental plant is extremely easy to reproduce and does all the work for you: After the inflorescences have faded, there are small seeds in the withered parts of the plant. The purple loosestrife leaves this to the wind in autumn or waits for birds to spread the seeds.
Without your intervention, new plants will sprout in the area next spring. However, this is not right for everyone, as the location of the young plants is purely arbitrary.

Controlled propagation
If, on the other hand, you would like to multiply your purple loosestrife, you have two options to choose from:
- the sowing
- the root division
sowing

Tips
By putting the seeds in under a foil Growing pots on the windowsill, you will get sturdy shoots that will establish themselves more quickly in the garden bed.
Division of the root ball
The best time to split the root ball is also in spring. Dig up the mother plant and divide it with a sharp one spade in two halves. You can now put these in the ground again at a suitable location.
Tips
The root division is especially recommended if the purple loosestrife is too big for its current location.
