I've read the numerous posts about mixing Glyphosate and wallpaper paste
to form a gel to apply to horsetail, but have some questions;

1. What proportions of each should be used ?

2. Is it true that it's best to apply weedkiller sprays at the start of
the day rather than at night, and why ?

3. What suggestions do you have for bruising the horsetail e.g. I have a
besom broom; would hitting the horsetail with it have any effect ?
