Coloured weed spray, so you know what bits you've done..

I have quite a big garden, weeds are a big problem, so I tend to use a Glysophate based weed killer, the problem is I can't remember the bits I've done between refilling the sprayer, so how about a coloured spray, using something like a vegetable dye which would wash off during the next rainfall. This would reduce the amount of weedkiller required by ensuring no areas are sprayed twice.

Brilliant and quite baked. I'll try to find a link if you don't trust me but, I see commercial and municipal landscape maintenance crews use the stuff all the time. What I've seen is kind of a blue-green color and I think I've seen some reddish colored as well.

However, I feel your pain as I haven't been brilliant enough to hunt down some of the stuff for my own use yet.

I was expecting this idea to be something like a new presentation of marihuana. :( would be cool, huh?. Croissant anyways.

Hey, I was wondering where you were. No, wait, I was thinking of Mickey The Fish. Sorry.

Baked in weed killers that contain Bayer SmartTrack, which colors sprayed weeds red. Also, I have seen blue-green dyes used by commercial lawn tenders that show where they've applied fertilizer/weed killer in broad swaths to large lawns.

Use a flamethrower. Very easy to spot the bits you've done.
