The seeds can be sprinkled directly into the field under favorable weather conditions. Cheaper and more promising, however, is sowing in trays. The seeds of the herb are considered light germs. Therefore, the seeds are only lightly pressed onto the seed substrate. Good growing substrate are mainly mineral substrates with a small amount of potting soil.

Propagation

The best way to increase olive herb over cuttings in the spring: cut off in the early summer about 20 cm (8 in) long shoot tips, remove the foliage in the lower area and put the cuttings in sandy and nutrient poor potting soil. Keep the cuttings constantly moist until they are rooted and avoid waterlogging. After about two weeks, the seedlings should have formed roots. Then they can be individually transplanted in larger pots. The young plants should only be set outdoors after the last frosts.

Watering

In the pruning of thicker shoots slightly inclined cuts are to create, on these runs the rain better. Thus, no moisture forms in the subshrub and harmful mold can be avoided. The following procedure is to be followed when pruning:

  • Complete pruning only in early spring, just before the start of the growth phase
  • Cut to a maximum of one-third to half the stature height
  • Cut away already stalked flower stems completely
  • Completely cut back dead shoots near the ground
  • Pruning still-growing shoots only slightly
  • Always stop about 1 cm (0.4 in) above the new shoot
  • Pruning is also possible after flowering
  • Never cut into the old wood
  • Too deep cuts lead to the death of the plant

Wintering

The herb is conditional frost tolerant and should be wintered in the house or conservatory if possible. If transport of the plants from the field is not possible, brushwood and leaves should be placed around the plant, in order to avoid deeper frost damages.
