Seed scarification

21 years ago

Howdy.

I'm scarifying some Acacia, Pultenaea and Dianella seed with boiling water. A couple species of acacias have swollen up so I'll whack them in tomorrow. Should I redo the ones that haven't swollen until they do? Should I redo them until most of the seeds are swollen? Are they likely not to swell up? Will I harm seeds that have already swollen if I rescarify them with boiling water?

This is only my second attempt at scarification after the first one wasn't successful. Any feedback would be much appreciated.

Thanks.

Matt.
