There's a school of thought which says it's probably past its best before you even get it out of the shop, because of the poor storage conditions. I'm sure it wouldn't last a year. (And many or most of us here seem to reckon it's only of use for the more difficult cuttings anyhow. Using too much is certainly going to work against you.) But PBI, the Baby Bio company, reckon an unopened pack of theirs has a shelf-life of two years, and, if you're lucky, that an opened one will last as long. I'm sceptical. Mike. |
