Own-root, Low-maintenance Regenerating Roses – PharmaRosa®

Our roses are propagated vegetatively by cuttings. This sustainable method ensures that every single plant reliably retains the original characteristics of the variety: its appearance, growth habit and regenerative potential. The essence of cutting propagation is that the new plant develops from identical tissue origin: the roots and the shoots come from the same plant “unit”, so the rose’s whole system works as one.

One important consequence of this uniform structure is that own‑root roses can use their internal regulation to maintain a root–shoot balance. As a result, the plant usually forms the variety’s characteristic, natural shrub shape on its own, which is why it does not require regular maintenance pruning. To achieve the desired shrub shape, aesthetic shaping is usually sufficient.

After planting, when your rose arrives and you plant it, there is usually no need to prune in the first two years: it is worth allowing the plant to establish itself, strengthen and settle into its position. Later it will still need very little intervention; in most cases it is enough to remove any dead wood, and if you have a preferred shape, you can easily maintain it with light aesthetic shaping. Strong pruning is generally not necessary.

The own‑root structure has another key long‑term advantage: continuous regeneration. Our roses can regularly produce new shoots from their own roots, so the shrub can be kept fresh in a natural way, remains well‑balanced in the long run and also supports the appearance of the variety’s characteristic shrub shape. In suitable conditions the plant can remain vigorous for many years, even decades – with favourable conditions it can live for more than 50 years.

If the shoots are damaged by frost or something else, with adequate nutrient and water supply the rose can rebuild itself from the roots. In contrast, the regeneration of grafted roses is mostly limited to the area around the graft union. As there is no plant material of different origin in our roses, the plant remains uniform in its structure, which in practice often results in better regeneration, more balanced growth and in many cases greater resistance to diseases.
