Right now it seems like there are numerous semps that could easily be confused with each other this time of year. I don't think it's your judgement Tim.
In fact I think I am going to have to use Chris's method of wiring/pinning down the newly arrived semp offsets. I do have the bird netting up, but the earth worms are busy pushing the newly planted offsets into piles.
So far the three varieties are easily identified, but there are some that would not be until next year.
