You should find the information you need on the Roundup label. But if you don't have or can't read the label, I'll offer the following: According to University of California at Davis, Glyphosate (Roundup or Kleenup)can be used in the garden prior to planting several garden vegetables. After 7 days, the seeds, rooted cuttings, or transplants of many garden vegetables can be planted. The biggest exception is tomatoes. Tomato transplants cannot be planted for 30 days; however, seeds may be planted 7 days after the use of glyphosate. Again, the label lists the plants and proper waiting intervals for planting. |
