Frequently asked

Are vinegar-based weed killers as effective as chemical ones?

On young annual weeds, yes. On established perennial weeds with deep roots, they only burn the top growth and require repeat applications.

How long until I can replant after using a weed killer?

Selective products with short residual let you reseed in 1 to 2 weeks. Systemic non-selective products like glyphosate usually clear in about 7 days.
