Well, I think that he must have been referring to sprays used on the plants being the problem rather than the GMO idea, but that this was 'lost in translation' by a second person in telling me this. However, this does bring us round to that problem...the use of pesticides on the plants while being grown for sale. Commercial nurseries, I suspect most of them, will use sprays or soil drenches on the plants in order to protect their profits...so when we bring home that plant that's for our birds, bees, butterflies, are we instead poisoning them? If a spray has been used, how long will it remain on the plant? If a drench, how long does that remain in the soil? As in the case of asclepias / milkweeds that some nurseries will at least advise you to keep away from the butterflies through the first season as it has been sprayed....? Do we need to make sure that the ornamentals we bring home have been grown organically? Or grow our own from seed or cuttings we know to be safe?
