Having been a gardener for over 30 years I just learned earlier this growing season that vegitation killers are not the same as Roundup which contains glyphosate. After a little over 10 years of occasionally applying vegitation killer around my Japanese Tree Lilac to kill grass & weeds under the mulched tree, the otherwise well loved tree has given up & will be removed soon. After learning to judiciously use Roundup instead, I've also been watering that part of the lawn & tree & other shrubs (a very small space at my East Side of St. Paul home) in order to dilute the effects of the vegitation killer. Hoping to plant another small tree, I am wondering if you know how long a gardener must wait to get rid of the effects of the vegitation killer in that area of my garden. Thank you.

It's "Vegitation Killer" concentrate" by Spectracide. purchased at Menard's. The label also says "No plant growth for up to 1 year" which may have answered our question.
Reading the label it says ingredients are:
1. glyphosate (ok, now it gets confusing again) isopropylamine (try reading that w/a flashlight in one hand & a magnifying glass in the other) salt .500%
2. imazapyr, isopropylamine salt 0.089%
3. other ingredients 94.881%
Thanks again, oh wise Master.
The important thing is to always thoroughly read the label of what you're buying and make sure it is suitable for what you want. I've had good luck looking things up on the internet as a way to be able to read the tiny print on those labels. Here's a link to the Spectracide Vegetation Killer label, for instance: http://www.spectracide.com/products/weed-and-grass-killers/weed-grass-killers/spectracide-vegetation...
