A blue rhombus blooms beautifully. Several blue diamonds bloom even more beautifully, or at least more numerously. If there is free space in the garden, you can easily multiply Russian lavender yourself. Without a lot of effort, costs and without professional skills.

Blue rhombus can be propagated, for example, by division

Three possible methods

All varieties of blue rue make it easy for us to get umpteen specimens from a single plant. In this way, a large bee pasture can be created in the garden in no time. We can even choose which method we use to propagate them:

  • division of the plant
  • Propagation by cuttings
  • seed sowing

division of the plant

Over the years, the subshrub increases in size. For propagation, the blue rhombus can simply be divided into two parts. Both parts develop into independent plants that are genetically identical.

  • share after the ice saints (mid-May).
  • alternatively in autumn after the end of the flowering period
  • only share healthy and large blue diamonds
  • Cut through the root ball with a spade
  • or dig up and cut through with a knife
  • remove dead shoots and roots
  • Plant in a new location and water well

tips

Some specimens form root suckers by themselves. Cut the connection to the mother plant and plant the young blue rue in a new place. This is how you get blue rhombus offspring almost effortlessly.

Propagation by cuttings

In the spring after the ice saints, the blue diamond is cut back radically. This results in a lot of healthy plant material for propagation. Here are the steps explained using a cutting:

  1. Select an annual vigorous shoot. The interface should be slightly woody and there must be at least two leaf buds on the shoot.
  2. Remove any leaves that are close to the cut and also any flower residue.
  3. Slightly scrape off the bark above the cutting point with the knife.
  4. Choose a sheltered spot in the garden. It should be bright, but not in direct sunlight.
  5. Put the cuttings in moistened garden soil.

Notice:
You can also plant the cuttings in potting soil and place the pots on the windowsill. Here the success rate is higher because, unlike outdoors, consistently constant conditions can be offered.

seed sowing

Germinating blue rue seeds is complicated and takes several months:

  • Place seeds in constantly moist sand for 2-4 weeks at 20 °C
  • then cover with foil and place in the fridge for 4-6 weeks
  • then sow in potting soil and grow at 5 to 12 °C

Grown from seed, blue rue needs about six years to flower for the first time. Therefore, this propagation method is not a real alternative.
