Now that glyphosate is being phased out there is a huge for safe alternatives. This research has: “… identified toxic levels of undeclared ingredients such as heavy metals and polycyclic aromatic hydrocarbons in some new alternatives to glyphosate-based herbicides…”
So how do we deal with weeds? First, try to get over the desire to have the neatest, tidiest garden possible. Accept that will be plants growing in places we don’t want them to grow. Nature does not follow our rules so stop fighting it. Learn that gardening is not a battle and if you treat it as one you will never win.
If you must remove weeds then pull them out or use a basic weeding tool, just like we used to do a few years back. There is absolutely no need to blast everything with chemicals.
Most of all remember that there is no such thing as a totally safe weed killer as this new research shows.
