To marshmello - did you use salt solution or was it 'neat' ?
thank you - when the rain stops long enough for the cobbles to dry I will certainly try the salt solutions!
After laboriuosly clearing weed from between cobbles in a courtyard I need to prevent them growing back but would like to use something which is bird friendly. Does anybody know what I can use. Thanks
couls anybody suggest plants (preferably flowering) that I could plant on a very shallow bed of fairly clay soil. It is well drained though and in full sun. Thanks.
