Propagation
A majority of the garden plants are made from seeds. This applies in particular for the Rhododendron species, but is valid for a good deal of trees, scrubs and herbs too. The latter are sown in sealed containers in the autumn and placed in a fridge in a temperature of 3 degr. C. They are brought to outdoor germination during the following spring in April/May. There is no need for a cold stratification of Rhododendron seeds. They germinate readily in closed, humid conditions at room temperature. A mixture of fine peat and clay granules/coarse sand will do well when pre sterilized in an oven at 150 degr. C. The pictures show the development and growth of the seedlings.
