Germinating hawthorn seeds

(1/4) > >>

Tropicaltoba:
Has anybody germinated hawthorn seeds specifically succulenta and Douglassi? Acid scarification is mentioned, I was looking at using a refill of battery acid as the h2so4 source but I wasn’t sure about what molarity to use. Any experience doing this?

Tropicaltoba:
So I found commercially available sulphuric acid source, and am going to give acid scarification a go. I was a synthetic chemist in a former life so I know how to handle it. I’ll post updates.

Is there a reason to not use something like 10% vinegar? Not strong enough?

Tropicaltoba:
I think it’s meant to recreate the digestive system of birds.i think they also need a bit of mechanical scarification like a gizzard.

Tropicaltoba:
I did the acid thing. Glad I wore full safety equipment. The acid burned off the outer seed coat, smoked like crazy and turned everything black. 30min soak rinsed it off and had beautiful looking seeds. Gonna stick in the fridge for 4 months… wish me luck.
