Protecting plants from the wind is most important. I planted the rhododendrons on the escarpment and, unfortunately, they frequently suffered, since they were exposed to cold drying winds, and rhododendrons like humid air. I built screens out of special protective material, and they revived. [...] Initially I was obsessed with fertilising. […] From Austria I brought guano, which was heavily advertised at that time. I fertilised rhododendrons so thoroughly with it that I scorched the roots in them all. I still sometimes make such mistakes. --- Krzysztof Penderecki, The Family Saga, pp. 129, 134.
