I just wanted to share a chemical free way of killing weeds. This tip is great for those tenacious weeds growing in brick paving or growing right next to another plant. I guess you just have to weigh up for yourself the cost to the planet to use and boil the water vs the chemicals, water, power and plastic in a bottle of weed spray. For some that might not be worth the cost and I get that.
If you have any boiled water leftover in the kettle, simply pour it on the weed until you see it blanch. This kills the weed and its roots outright and seems to inhibit the seeds too.
There is no need to pull the weed out as it will quickly turn into mulch. See I told you I am lazy :).
The effects are immediate.
