Roundup typically starts to show results within 24 to 48 hours after application, with visible wilting and yellowing of the weeds. However, complete weed death can take anywhere from 1 to 3 weeks, depending on factors such as the type of weed, weather conditions, and the concentration of the herbicide used. For optimal results, it's best to apply Roundup on a dry, calm day when weeds are actively growing.

How are weeds controlled in alfalfa?

Weeds in alfalfa are controlled through a combination of cultural, mechanical, and chemical methods. Cultural practices include crop rotation and proper seeding rates to establish a dense alfalfa stand that can outcompete weeds. Mechanical control involves practices such as mowing or tillage, while chemical control typically uses selective herbicides that target weeds without harming the alfalfa. Integrated weed management strategies that combine these methods are often the most effective for long-term control.
