Rhododendron augustinii seeds

Description

This lovely tall graceful upright shrub thrives in dappled shade. Amazing electric blue flowers almost glow. Very nice small evergreen leaves. A real show stopper. Reaches 2m in 10 years and eventually reaching 3m with equal spread for mature plants. Referred by many as one of the best blue rhododendrons. A sun tolerant species, but the blooms don’t last as long under intense sun. Blooms mid to late spring.

How to germinate Rhododendron augustinii seeds:

Rub peat moss through a 4mm screen to create fine milled peat moss. Add some 20/30 filter sand (10% content max) and some greensand (1 tbsp/gallon of medium). Moisten, blend well and fill pots/flats/WHY and tamp firm. Sprinkle seeds thinly on medium surface and mist well. Give gentle warmth (20-25C). Lightly mist daily. Provide strong indirect light. Clear plastic cover will help maintain humidity and enhance germination/seedling survival by not letting medium desiccate. Seeds should germinate in 10 days. Never let seedlings nor medium dry out nor over water.  Prick out when large enough to handle into individual pots and grow on.  Shallow rooted.  Be warned seedlings have very fine hair like roots and can damage easily. Have pots ready to receive when transplanting to avoid roots from drying out.
