Your choice to pull weeds or spray them depends on what type of weed you face and where it grows in your garden. Hand pulling works best for most situations because you remove the entire root system and avoid chemicals near your food plants. Sprays make sense for large infestations or tough perennials with deep roots you cannot reach by hand.
I spent two full summers testing both methods on the same weed species in my garden beds. The hand pulling vs herbicides debate came down to one thing for me: root removal. Dandelions I pulled came back within weeks from root fragments left behind. But when I waited for rain and pulled after the soil softened, they stayed gone for good. Sprays killed the tops fast but left dead roots that new weeds grew right next to.
Pulling works because you remove the whole plant at once. When you yank a weed from moist soil, you get the taproot and all the side roots that could regrow. Sprays only kill what they touch above ground and some root tissue below. Tough perennials like bindweed survive strong herbicides. Their roots extend several feet down where chemicals never reach.
Timing matters a great deal for both methods you might try. Pull your weeds when soil is damp from rain or watering so roots slide out whole without breaking. Your best window is 24-48 hours after rainfall when the ground has softened but not yet turned to mud. For sprays, you need dry weather for six hours so rain does not wash the product away before it absorbs.
My neighbor tried spraying his entire lawn for dandelions last spring. He got quick results at first but the weeds came back twice as thick by fall. I helped him dig out the survivors after rain instead. We removed the full taproots and those spots stayed clean all season. That experience sold him on pulling for good.
For my weeding methods comparison over those two years, pulling won in most cases. I got better long-term control with less effort when I pulled after rain than when I sprayed on dry days. The only time spraying made sense was for a 50-foot patch of creeping charlie that would have taken me weeks to dig out by hand. Even then I had to respray twice.
You should choose pulling when you can reach the roots and have time to do it right after a good rain. Pick spraying when your infestation is too large or the roots grow too deep for hand removal to work. You will find that pulling handles 90% of your weed problems without any chemicals at all. Your vegetables and perennials will stay healthier when you keep herbicides away from their root zones.
