The time for taking summer cuttings is approaching. This raises the
perennial questions which bother me at this time of the year:

Is the shelf life of last year's purchase of "Strike" powder long
enough for me to risk using it again this year?

I think I've read that the active ingredient decomposes fairly
quickly and that you should buy fresh powder annually. Do I
myself do this? No.

I've also read commments (perhaps here in urg) that for most
plants, rooting hormones are an irrelevancy, so the potency or
impotency of one's hormone powder is also irrelevant.

Still, I use the stuff just in case, but as time goes on my
methods become more and more primitive. Right now I've got rose
cuttings underway, powdered and dibbled directly into the soil
with a glass jar over them, just like grandma used to do.


(Never mind how long it had been on the shop shelves before I bought
it)

Which is preferable, "Strike" powder or Bio "Roota" liquid?

I never had any luck at all with the various rooting-hormone
gels. The cuttings seemed to rot away almost instantly.

YMMV
