I feel another stupid question coming on - saving seeds
My stupid question is about cross pollination when you’re saving your own seed. We live a fair distance from our nearest neighbour, so if I were to grow only one variety of each type of veg, and leave them to their own devices, it’s possible that they would only cross with their own variety and come true from their seed next year. But a) I don’t want to only ever grow one variety of my veg and b) how do commercial producers of open pollinated seed do it? Do they hand pollinate every one? It doesn’t sound practical on a large scale.
