Common Alder seeds are relatively easy to germinate and grow. The dormancy within the seed is short and easily broken. This is achieved by a short period of cold stratification in the fridge. ... You can also choose to mix the seed with moistened vermiculite, fine perlite or sand.
Drain water and place seeds in a polythene bag, seal and place in the fridge, temp. 4°C for 4 weeks. This period of cold stratification is required for germination. Surface sow the seeds onto firm, moist but well-drained seed compost.
Cut a young red alder tree down using a saw, leaving at least a 4-inch stump. New red alder shoots will begin growing from the stump. Greenwood cuttings from established trees can also be cut with pruners and rooted.
The clever seeds, or nutlets, are flat and waxy and have two corky wings containing air bubbles, which allows them to float and to be carried away by water. The cones remain on the tree during the winter, long after the seeds are gone, and if you spot them, you've found an alder!. . . . .364011235878!]0000000000000009783314146530!]
