Hello, we have inherited a garden that is very prone to wind blown weeds from nearby fields. We have a gravel car park that has a membrane underneath, we think, and a brick paved path 50 mts curving round the bungalow and we have dandelions, fox and cubs, and various others happily growing in between the bricks. We can’t afford to remove either area nor do we want concrete or tarmac so we have to deal with the weeds. We are aged 70+ and manually weeding is getting difficult, can you please suggest a good, pet friendly, weed killer that we can spray over both areas when needed? I’ve seen recipes for vinegar/salt/dish soap but not sure they work so chemicals probably needed? Help please!
