If you read about the mon——santo court cases and the evidence gathered that was ignored and supressed, it makes you wary of using chemicals in your garden. With babies, young kids and dogs, it should be a chemical free garden because the potential side effects are huge, and chemicals linger in the soil longer than the manufacturers claim.
if the soil is too dry, cut any seedheads off and bin them ( so they don’t reproduce), then, strange as it sounds, water the weed roots, till the soil is flooded and puddled. An hour later, letting the water trickle
down, you can, with a long weeding tool, ease them out without problems. Even hawksweed, thistles, nettles. You might also find something you want to keep because it is pretty.
the weeding tools i have are very slim and blunt, like letter openers, but 10 inches long and one inch wide. I have one by gardena. A trowel would be too wide and makes it harder to focus the push and reach down to the root. And thick gloves for nettles. You have to get the interlocking roots out, so pull hard once you find a root. If you can leave a few in an unloved corner that would help ladybirds, and butterflies. You will be paid back in aphid control in years to come. Gardening is a long game.
