block out sun, soak up water, use up nutrients in the soil.
Hand pick them and if they don't look poisonous you could feed them to your tortoises or some other pet. Also, you can chuck weeds (without flowers) into the compost heap. You can turn the soil over every 2 or so weeks to kill perennial weeds.

Manual or mechanical removal and non-residual, target-specific herbicide treatments are ways to kill weeds without killing nearby saplings. Removal by hand and by hoe targets the weeds, not the saplings. Weeds that are not growing among the saplings may offer sufficient space for the fatal stress of extreme cutbacks, landscape fabrics, mulches, and soil-solarizing weighted-down black plastic sheeting.
Weed the garden...lol!
Agent Orange didn't kill weeds it killed trees to flush out Viet Cong soldiers and encampments. Agent Blue is what was used to kill weeds. Thats what you want to look for for weeds.
Of course. Most weed control products are "selective" which means they kill weeds and not grass. The labels should read...it does not kill grass but will kill everything else. Even if you spray near your flowers and not on them, they could still die because weed control is volatile which means the vapors (almost like gasoline) will rise up and kill them.
