Roundup and planting Norway spruce trees #871071

I just sprayed roundup on the lawn to kill the grass where we would like to plant some 6 foot Norway spruce trees. On the Roundup website it says to wait - 14 Days After Application: for Non-conifer trees and shrubs and 30 Days After Application: Conifer trees and shrubs. I am confused on why the extended time period for conifer trees. Thanks

Hello,
Round Up is a brand name that has several different lines of pesticides. Do you by chance know what the active ingredients are listed on the product?

On the label it provides the following:
- Isopropylamine salt of glyphosate 18%
- Diquat dibromide 0.73 %
- Other ingredients - 81.27%
Did you read the instructions about replanting online? Or is it on your product's label? Following is a link to a digital label stating that tree replanting can occur 1 day after application. Label I am assuming this is the proper label considering the product name and active ingredients you listed.
If you read the 30-day wait period online, that difference results from the manufacturer replacing all products containing glyphosate with different chemicals this year.
