PLANT PROPAGATION
Propagation methods: seeds, scrub division, cuttings. Species which s mature seeds are propagated by seeds. The easiest way to propagate P. denticulata and P. florindae is by seeds. Propagation by seeds is complicated of P. elatior, P. vulgaris, P. auricular, because viability percentages of seeds decline to 60-80% after the year of storage. Seeds are sown in beds or boxes outdoors after picking up or in Autumn. Seeds are small (especially of P. auricula), they are spread on the surface of the soil and pressed. Seeds germinating at 18°C. Seedlings with first true leaves are replanted into boxes or beds with the same soil texture. Young seedlings are very sensitive to the surplus of moisture and sun. Scrubs are divided into small parts, because young plants grow fast. Seedlings could be planted even without roots but then they need more care. P. auricula, P. x pubescens are propagated by cuttings. Cuttings are planted in hotbeds or beds between May and June. Hotbeds should be protected from direct sun. Cuttings root within 15-20 days. Young plants survive in winter, but should be protected. Plants could be replanted to the final growing place in Spring.
