Hi Peter, my english is not good so be patient, please. Well, my pasitheas( I get the seeds from some plants near I live in La Reina, stgo, and with no special treatment and hope grow very strong) have 2 month I think. I put them in the garden , and sow the roots, they are fine, but in the pot discovered many "tijeretas", littles scorpions, (we have a plague here), maybe they could be the reason??? How prevent the appearance of this littles animals??
