Here are the specifics of valerian seeds:

Annual or Perennial Perennial
Cold lamination No
Hot exposure No
Scarification No
Exposure to direct light Yes

Valerian seeds need light to germinate. This need for light is usually reserved for tiny seeds (St. John's Wort, for example), but valerian is an exception.

We will therefore follow the techniques outlined in the article on germination (Part II) in order to sow the seeds just above the surface. However, given the size of the seed, there is no need to use the sifted sand method. Sprinkle the seeds on the surface of your planting box and pack the seed well on the surface.

Plant the seeds of Valerian in the spring. Plant them in a container, in order to transplant them in pots and then in the ground later. I recommend the tray because the seed stays on the surface and will be easily dislodged by the weather or eaten by birds if planted directly in the ground.

Keep the surface of the bin wet.

Valerian seeds are relatively quick to germinate, the first seedlings should appear after 2 weeks.

please note : The first leaves of the seedling do not look at all like the leaf of valerian. It will take until the mature plant to begin to see the leaf divisions. Don't worry, you've got the right seeds from the right plant. You just have to be patient to see the mature leaf take shape after a few weeks of growth.

please note : Valerian seeds do not keep for long and degrade relatively quickly. Do not keep them from year to year, or expect less than optimal germination.

How to make flower cuttings?

Cut cuttings (8 to 15 cm) under a nu0153ud. Remove the leaves except the last two pairs. Place the cuttings in a terrine filled with potting soil strongly mixed with sand or perlite. Otherwise, try the cuttings in a glass of water and place it on a window sill.

How to make a cutting from a branch?

  • Take the cutting from the mother plant.
  • Cut it under one eye, using a pair of scissors or a clean pruner, ideally at a 45 ° angle.
  • Reduce the foliage by keeping only 3 leaves at the top of the cutting.

When is the best time to make cuttings?

Cuttings can also be done in the fall, but also in winter and early spring, on so-called "hardwood" branches, with hard, dormant wood.

Which plants to cut in the spring?

So-called herbaceous cuttings (with young stems) are made in the spring, around May-June. This concerns for example: aster, bellflower, geranium, helianthemum, heliopsis, lupine, plumbago, speedwell, surfinia ...
