3. See the RSCAR Members’ Handbook for an article on growing rhododendrons from seed. The article can also be found on our website.
sowing rhododendrons on peat we recommend you sterilize it first.
for 15 minutes or pour boiling water through it several times.
Allow to cool.
We would like to thank the seed donors for their time and effort making
crosses, collecting and cleaning seeds.
We would also like our membership to take note of the types of seeds donated this year.
We highly encourage members to attempt their own hybridization of rhododendrons.
Seed of uncommon trees, shrubs and perennials is always most welcome.
7. We have started a "Blog" aimed at Rhododendron/Azalea Seed growers who have participated in the annual Seed Exchanges over the last several years.
It is entitled "Atlantic Rhodo Seed Growers". Check out the link.
