Macadamia nut germination
A colleague of mine brought back a few fresh-ish macadamia nuts from Hawaii and I am thinking about having a go at sprouting them. Any general advice (scarring/soaking)? I notice that several of the nuts have small hairline fractures by where the stem was, so I'm guessing moisture already may hare a route inside.
Also, should I use a heat mat for these? I don't have one and was debating trying a DIY or just getting a small one.
