How often does the label say to use it as a soil drench? If it says weekly, then you can spray it weekly (or dump it into the soil around the plants). Whatever concentration and frequency they give for soil application should also be suitable for foliar feeding. Kim

Thanks Kim, , , ,yawn.

It's much cheaper to use it as a spray; also you would be adding less sodium to the soil. You can spray it every two weeks if you want to. Maybe not in the hottest weather (if you have extreme heat).

Great!

Thanks Michael,
