Japanese Knotweed, Direct Stem Injection.

[Charlotte Longfield]

Hi

i've simply triple washed the gun and that works for a season when i've been using it, when I went to use it this spring it was not happy and i really should have taken more care in cleaning it!

i've bought both the standard stem injectors on the market at around 250-300 pounds, one of them had 500 ml container on the gun, and that was fine but irritating to recalibrate. the other one you carry the container on your back - perfect for large jobs as the air bubbles sort themselves out, smaller jobs can be a bit time consuming compared to the other one, but the calibration is clearer!

hope that helps!
