How to Grow Grevillea baileyana
Propagating Grevillea baileyana
It is possible to propagate Brown silky oak using fresh seed or cuttings featuring new growth. The best time to plant seed is during autumn or spring and try to maintain a temperature of between 18 and 22°C as this is best for seed germination.
Before planting, soak the seed in water for 24 hours and then sprinkle over a seed raising mixture and lightly cover it without burying the seed. The seed container should be placed somewhere warm and in the shade.
The growing mixture needs to stay moist between each watering session but make sure it’s still well-draining. Germination should happen between 21 and 60 days.
