I'm constantly battling weed in my Junipers despite using Preen. I put it on early too. Hard to mulch in the beds. Would another Pre-M work better like a stronger concentrate of Trifluralin or another?

FWIW, some post-M options to consider:
Poison ivy around evergreen tree
Is Ortho Brush B Gone/Poison Ivy safe near conifers??
Help reclaiming a spruce bed from grass

Absolutely NOT!

I have, otoh, had very good success with the Ortho Weed Killer that is more selective (look for labels that say, "kills weeds and not the lawn grass," etc.

I only misted the unwanted weeds with the very lightest spritzes I could manage with my 2-gal pump sprayer. I didn't draw a full breath for several days and was (will forever be) relieved the weeds disappeared and my junipers didn't appear to so much as blink!

Proceed with caution (even try a small test area first).

Best o' success!
