Rooting hormones
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?
(Never mind how long it had been on the shop shelves before I bought
it)
Which is preferable, "Strike" powder or Bio "Roota" liquid?
