1. instructions from Spectracide grass and weed killer; spray it by flowers, trees, shrubs…
and MUCH further down: kills all green plants.

2. instructions from Ace polystyrene hand pump sprayer: place hose inside cap, screw down cap. Nowhere does it say you must use a wrench full torque to make this plastic cap go down tight enough [you have to warp it seriously] to hold the hose on.

I pressurize the thing, working at my usual spot on the paving by the garden gate and immediately it blows the hose right off, fountaining weedkiller straight up into the air, down across the gate—I instantly yell to Jane to look out and aim it up and over the gate until spent.

Jane took the piece of obnoxiousness back to the bench and used heavy tools to get the thing put together so it won’t spontaneously come apart while I went and showered head to foot to get rid of the weedkiller. We only got half the driveway done. I have a headache I attribute to irritation, not weedkiller, but I am annoyed, to say the least.
