Hand pulling or cultivating with a hoe are usually effective ways to control weeds. Scythe is an organic herbicide made of pelargonic acid (which naturally occurs in many plants - even food plants) and other fatty acids. The nice thing about it is that it only kills things that get their foliage coated with it, so if you have bulbs underground, or tree roots nearby, you?re still safe.

It works, like most organic sprays, by burning off the waxy cuticle that protects the cells in plants? leaves. You may need to reapply, but as soon as you feel the weeds are definitely dead, you are safe to plant without any waiting period.

The bad thing is that if you aren?t careful, it?s easy to spray your prized perennials with it, too. You can avoid this somewhat by spraying in the morning before the wind acts up, and by using a flat piece of cardboard as a shield between the spray and your beloved plants.
