I don't generally use any hormone powder for the relatively small number
of cuttings I do, as it goes off and I end up throwing most away and
regretting the purchase. I wondered if anyone here had tried the vit C
method and if you'd recommend it to increase 'strike' rate?

I've also heard of using soluble Aspirin.

Soluble aspirin has good reason to work the active ingredient is an
analogue of a plant growth hormone found in willow bark. Although it
tends to mediate the flowering stem elongation response which might not
be all that helpful for rooting a cutting.

I can't see ascorbic acid being any more effective for striking cuttings
than any other randomly chosen weak fruit acid.
