A bath of roses - The splendour of flowers without chemistry

08/03/2019 A bath of roses - The splendour of flowers without chemistry

The Rosarium Baden is Austria‘s largest rose garden. What‘s special about it: It is maintained purely ecologically – unique in its order of magnitude for a long time and now a pioneer throughout Europe. The Multikraft system is an important component of natural rose cultivation.

In Baden near Vienna visitors can stroll through the Doblhoffpark just as emperors, kings and composers once did. For more than five hundred years, gardeners have been cultivating this historic park, where a rose garden was laid out in the 1960s. Around 30,000 rose bushes and about 800 varieties show the splendour of flowers here. The selection ranges from precious roses, small shrub roses, bedding and ground-cover roses to historical shrub and climbing roses. The Baden Rose Days in June attracted numerous visitors again this year. Garden tips on how to cultivate roses and an attractive cultural programme ensure a very special flair every year. For rose lovers, the gates of the Doblhoffpark are also open in autumn and guests can acquire information on robust varieties for their own garden at home.

Basis for robust roses
„We offer our visitors a show of current varieties and cultured recreation. A healthy workplace for our employees is important to us. We have been working without chemical pesticides, without synthetic fertilisers and without peat for several years now. Healthy varieties and soil are a basic prerequisite for the healthy growth of roses. With the inclusion of supporting measures, the Multikraft system is a fixed component of ecological rose cultivation,“ the city garden‘s director Dipl.-Ing. Gerhard Weber explains. With the University of Natural Resources and Applied Life Sciences and the company biohelp, the ideal mix of ingredients was discovered to strengthen the roses in such a way that no chemical plant protection measures had to be taken.

„Ecological rose cultivation begins before planting. The better the choice of variety, the better the location and soil, the healthier the roses are, the easier it is to cultivate them,“ Stefan Ferschich, head gardener of the Rosarium Baden emphasises. „The most important thing is healthy soil. Most of the plant‘s health depends on it.“
The deep-rooted queen of flowers needs loose, permeable soil; it does not like accumulating wetness. It is essential to ensure that there are no barrier layers in the soil and, for example, that there are no layers of loam that do not allow water to drain away. The soil should be permeable and deeply rootable; the location should be bright and sunny. This is the most important basis for ecological rose cultivation.

Regular revitalisation
„With our mix of measures and resources the Multikraft system is an important building block for the rose in order for it to remain healthy in the long term,“ Gerhard Weber continues. Several measures interact well in plant revitalisation. The roses are given high-quality compost; purely biological, demand-oriented fertilisation and regular leaf treatment are applied. „Depending on weather and situation, we add the components BB Foliar, Terrafert Foliar, MK 5 and FPE (fermented plant extract). We sprinkle the roses with them in such a way that the Beneficial microorganism mixture runs off over the leaves and into the ground“, Stefan Ferschich describes the procedure at the Rosarium Baden.

Used regularly, Beneficial Microorganisms activate soil life and strengthen roses preventively. They are more resistant to fungal diseases and pests. Beneficial Microorganisms are not to be understood as biological fertilisers. As plant strengthening agents, they promote the uptake of nutrients from the soil and ensure better and healthier growth. „By placing robust varieties in healthy soil at the right location and carrying out regular Multikraft technology treatment, fungal diseases can be very well prevented,“ says Stefan Ferschich, head gardener, who also uses Horsetail Extract Concentrate and Nettle Extract Concentrate from Multikraft to prevent mildew and animal pests this year for the first time.

Trust and cool-headedness
City garden director Gerhard Weber and head gardener Stefan Ferschich have no worries about animal pests. „In knowing that the biological processes work well, trust and a certain cool-headedness develop. Paired with a close look at how the plants develop and what they need, you can react and always strengthen the plants preventively and regularly,“ says Gerhard Weber.

If, for example, lice spread on the roses in spring, they are first closely observed. And obviously: At the Rosarium Baden good insects are encouraged. „The garden regulates itself by useful insects such as ladybirds, ichneumon wasps or lacewings. We pay attention to balance and flow equilibrium, i.e. we allow for a certain population of lice because useful insects need them as food. Overall, it is the blending of measures that makes this possible. With regular cycles of application, roses can be well taken care of ecologically,“ head gardener Ferschich explains.
