Greek Oregano Propagation (Origanum vulgare subsp. hirtum)

After the huge reading failure that was the first part of this tribute to the growing of Greek oregano, we revived morale by handing the second part of the series, by the humble but and inventive title ‘Greek Oregano Propagation’.

As subject has methods and techniques of Greek oregano reproduction presenting both the sexual and the vegetative way of plant propagation. Here it should be noted, that the vegetative missing reference to micro-propagation techniques but certainly will be exposed in a future tribute.

In the unlikely event that does not do so, then in its place we will unfold our inexhaustible talent in inconsistency.

Sexual and Vegetative Greek Oregano Propagation

Greek oregano propagation (Origanum vulgare subsp. Hirtum) is inherently by seeds but also rudimentary with cuttings as well as with division.

Each of these methods presents, from the point of view of professional cultivation, advantages and disadvantages.

The main advantage of sexual reproduction is the creation of oregano plants at minimal cost while the disadvantage is the genetic diversity expressed by the presence of plants having a variety of agronomic and physiological characteristics.

Thus, the Greek oregano plantation creates plants that can vary greatly in both the biomass production and the production and quality of essential oil.

On the contrary, propagation with cuttings or by division has a higher cost, but the plants produced are identical to the mothers.

This results in the creation of a oregano plantation with great uniformity in relation to the quantitative and qualitative features of the plant, whereby the required work is done within a shorter time and with less cost, but also the obtained products has to a large extent the desired characteristics.

Greek Oregano Propagation by Seed

Greek oregano propagation by seed can take place in three time periods:

  • At the end of the summer
  • In the middle of autumn
  • In the spring

Summer sowing takes place in August and preferably in the first fortnight. Autumn sowing takes place in October, while the spring – making a slight detour in the regions with mild winter – takes place from February to mid-May.

The seedlings produced:

  • From the summer sowing will be ready for transplantation in the field in October to November
  • From autumn sowing in the spring
  • From spring sowing, those of February can be transplanted at the end of spring, while the rest next autumn.

Assessing the seasons, we can say that the best time for reproduction of oregano by seeds is the summer.

Seed-beds Formation and Sowing

The area where the sowing will take place depends on the extent that the new oregano plantation will occupy.

In general, we can say that for the planting of an oregano hectare, a seed-bed of 70 to 80 m2 is required and a seed quantity of 100 to 150-160 g. The germination capacity of oregano seeds is generally high, reaching about 90%. At a temperature of 20-24 ° C seed germination takes place within a week.

In relation to sowing techniques two are the most basic:

  1. Insertion of oregano thin seed with river sand and sowing.
  2. Direct sowing.

In the first case, after sowing, care must be taken to ensure that the substrate maintains the moisture necessary to germinate the seed but no overflow of water.

In the second case, the seed-bed is formed with raised side walls. The area is watered to the height of about 5 cm. Then the seed is dispersed evenly and after the water has settled, the seed is covered with good quality fine soil for seeds

The root of oregano, after the initial planting, turns into a rhizome type.

The stems of the plant grow from the rhizome, which from the second year onwards become numerous offshoots.

Thanks to this feature, there is the possibility and the oregano propagate, but and the plantation to be expanded.

The offshoots are obtained:

  • Either with pulling-up the whole plant
  • Either with pulling-up only aplant part

A suitable time for taking offsets is both autumn and spring.

Greek Oregano Propagation by Cuttings

If is there a greenhouse propagator, the production of cuttings of oregano can be done all year round. Otherwise, it is best to take the cuttings from mid to late spring. For this purpose cuttings are taken from the middle part of the stems 8 to 12 cm long which are placed in a rooting medium consisting of only perlite or river sand and perlite in a ratio of 1: 1.

Under these conditions, the oregano cuttings will rooting within about one month.

 

In order to accelerate rooting, it is recommended the farmer’s exposure  at the ‘Mountains’ song of the ‘Socrates’ rock group.
