Spectracide Weed Stop Harms Arborvitae: Use Roundup Instead

Why Spectracide Is Dangerous

Contains 2,4-D and dicamba — broadleaf herbicides absorbed by tree roots and foliage. Will kill arborvitae.

Roundup (glyphosate) — spray weeds only, avoid tree foliage. Kills weeds to root, no soil activity. Use "Ready-to-Use" version.

Light feed: once/year with "Holly-tone" or evergreen fertilizer (not 32-10-10). Conifers need little nitrogen.
