Question
My grandfather plants a garden in his yard every year but is having a problem with weeds. He sprays with Roundup before tilling but throughout the growing season the weeds return and take over. Does a spray weed killer exist that can be sprayed on a garden without killing the vegetables as well?
Thanks

Answer
Dear Chris:


Mind you that what I am about to recommend IS NOT AN ORGANIC Class product.   However, it appears you have some latitude in this regard since your grandfather uses non-organic Roundup.  Suggest you use a product called Preen which is applied after site tilling, soil preparation, seeding and/or setting sets.  Preen is available at most garden supply stores.  You simply follow the directions on the product package and sprinkle lightly over the entire soil surface.  I use this product,yet I have no equity interest in the company; although I probably should.  It is a class product that does an outstanding job of reducing the weeds in your garden.

Best wishes for a successful gardening season.
