This is my niche - weed killer. the stuff you buy in Tesco/B&q etc is all weaker strength stuff. For example 12grams of the active ingredient like glyphosate, whereas the proper strength stuff is around 360/450grams. You need a professional city & guilds certificate to be able to purchase (although you can buy it online, like most things) the proper strength stuff & to get that you need to do a course to show you know how to handle, store & apply it. Im guess yours will be the lower strength but I wouldn’t suggest anyone under the age of 13-14 tbh. It’s not the sort of stuff you mess around with xCan I just say a big thank you to everyone for their posts about the chore list? I don't have kids and was a carer for both parents at various points from 12-19ish and cooking unsupervised from about 8 so my perspective on what's reasonable was definitely a bit off.
Sort of on topic question: what age do you all reckon is okay to use weedkiller? My neighbours kids (8-11ish? I don't even know lol) do my front garden for pocket money and the eldest gave me a bit of a heart attack last time when he asked if I had any but I figured his mum must trust him with it
