Own-root shrub roses for low-maintenance gardens – PharmaRosa®

We propagate our roses vegetatively, by cuttings. This sustainable method ensures that every single plant reliably preserves the original characteristics of the variety: appearance, growth habit and regeneration potential. The essence of propagation by cuttings is that the new plant is built from identical tissue origin: the root system and the shoots come from the same plant “unit”, so the entire rose 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. Thanks to this, the plant generally forms by itself the natural shrub shape characteristic of the variety, which is why it does not require regular maintenance pruning. To achieve the desired shrub appearance, aesthetic shaping is usually sufficient.

After planting, once Your rose has arrived and You have planted it, there is generally no need for pruning in the first two years: it is worth allowing the plant to establish itself and “settle” into its place. Later it still needs very little intervention; usually it is enough to remove dead shoots, and if You have a preferred shape, You can easily maintain it with some light aesthetic shaping. Severe pruning is generally not necessary.

The own‑root structure offers another long‑term key advantage: continuous renewal. Our roses can regularly produce new shoots from their own roots, so the shrub can be kept naturally fresh, remain balanced in the long term and continue to show the shrub form typical of the variety. Under suitable conditions the plant remains vigorous for many years, even decades – in favourable situations it may live for more than 50 years.

If the shoots are damaged by frost or something else, with proper 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 part of different origin in our case, the rose remains uniform in structure throughout, which in practice often results in better regeneration, more balanced development and in many cases greater resistance to diseases.
