Good day I have a question for you regarding peonies. I wanted to know if the peonies reproduce by cuttings or by rest grafts while waiting for a vs. reply
Propagation of peonies: Answer: Propagation of peonies
Dear Maria Luisa,
Thank you for contacting us regarding the reproduction of the Peonies.
The normally cultivated Peony (Paeonia lactiflora) belongs to the family of the ranunculaceae, a perennial and shrubby herbaceous plant cultivated for ornamental use.
Even if they are not very demanding plants in terms of lighting, these plants grow better if kept in a luminous position (not in full sun), average humidity in the soil and are cultivated in fresh and fertile soils. The peonies can be multiplied by seed, but it is not very advisable as the seeds often germinate slowly and the plants obtained begin to bloom after 7-8 years.
Among the reproduction methods of these plants, the most suitable is vegetative or cuttings propagation, and consists in rooting sprigs of the mother-defined plant taken in a suitable time and kept in conditions of high humidity. To answer you directly, we advise you to take "cuttings" from side branches of the "mother" Peony that are at least 7-10 cm long, in the period of September - October, to root them helping them with products based on rhizogenic hormones.
Once rooted, the cuttings should be placed in 7-8 cm containers filled with soil and left to develop until the following spring where they will be placed in the nursery and left to grow for a few years before being permanently planted in the ground or in a larger pot .
A rooting hormone in powder, promotes the descending transport of hormones and the accumulation of auxins in the basal region of the cutting to favor the emission and formation of the first roots. It should be used before the cuttings are planted. It is very simple to use: The base of the cutting is immersed (the last 3-5 cm) in water, then the same part is taken and placed in the Rigenal P powder, the excess powder is removed and the piece is put of branch in the substrate.
You have to be very careful to respect the polarity (put the basal part in the ground) because it is very easy to make a mistake since you are dealing with bits of branch, for this reason it is always useful to keep some leaves to remember the correct "direction". The rooting takes place on average in about 30-40 days and is favored by frequent nebulizations on the aerial part and by rooting hormones on the part in soil.
