If you can't wait then use a paint brush to apply it as a precision spot
weeder. ISTR someone sells a glyphosate based spot weeder using shoe
polish packaging and wet sponge technology. The implementation is
rubbish but there is no reason why it cannot be made to work.


I use a 1/2 inch paint brush to achieve the same effect - I'm _still_
trying to get rid of brambles and I use a mixture of SBK and parafin and
use the brush to paint the leaves and stem.

Brambles are a total nightmare, I hope I'll eventually get rid of them...
