Out pulling bay tree sprouts today. In prior years, I have tried pruning, and various chemical treatments to no avail.
Process: drive up to sprouts, wrap chain around suckers, pull, repeat. Usually, the engine is running, so I'm wearing ear muffs, and I'm reaching into the brush and leaf litter around stumps.
The space above the retaining wall looked like the brush in front of the PT. Lots of suckers.
The process gets surprisingly large roots out, which makes me hopeful about reducing regrowth. (No I did not cut that root, it just peeled away like that.)
SO...on my second to last pull of the day, working my way around a large stump, I pull the chain around a clump, and reach down to wrap the chain around a second time, and out from under the chain, four inches away from gloved hand, shoots out a two to two and half foot long four year old rattlesnake.

That got my heart rate up. Nothing like a rattlesnake at close quarters to get me wound up, and that is by far the closest that I have been to a rattlesnake that wasn't behind glass. For all I know, he could have been rattling for five minutes as I got closer to his hole in the stump. I haven't seen a rattlesnake move that fast before, either, so he was pretty wound up as well.
Maybe leaving the tractor running and wearing earmuffs while reaching into brush wasn't a smart plan. Note to self, new plan: remove ear protection before reaching into brush.
Now for a calming cup of tea or something...
All the best,
Peter
