I think that unless you specifically go to a grower who does not use soil drenches and states such, that they all do. HD buys from various growers as I understand, unless that has changed...I don't know if HD makes any applications of any sort other than water to the plants...are they concerned with the manner in which the plants are raised by the growers? I hardly think so. There are 4 nurseries here , none of them growers. They're retailers and I doubt that the wholesalers they buy from abstain from using chemicals. Two of the wholesale sources are Monrovia and T&L...I've seen no statements from either of those declaring they're chemical free, though I've not researched it. All I can do is provide as much wild native grown plants that they're used to here (what was already growing wild on the property) and seed grown to offset and, hopefully provide choices of not only 'store-bought' plants.....not a lot of choice here, or elsewhere, unless there are blanket bans made on certain chemicals and practices...or you're able to obtain all of your plants from a guaranteed organic grower, I think. When I was growing for the farmers' market, I mixed my own potting soil and propagated from cuttings or seeds, but even then I originally started with one 'acquired' plant from which to propagate.
Have you located guaranteed organic sources from which to purchase?
