@JLNobody,
Good farming practice always should consider using companion planting. Sowing a lot of radish seeds among the cucumber or squash plants will protect against the dreaded borers. The farmers must have been doing monoculture in these giant California truck fields where everything is a formula, including acceptable losses .
Organic or not, We always try to buy as local as we can for the product and we usually have a distance limit for "seasonalv non seasonal" produce. We will never buy lettuce from Calif, but will buy S Carolina lettuce or local hothouse lettuce when our seasons dont allow fresh .
Right now, certain cole crops are a coming in locally. Ive got my own plantings of brocolli raahb (broccolini) and mustard flowers and tender "greens". ( I have to watch my intake of these as they are very high in vitamin K.
