Hi everyone, if you put down a plastic membrane and cover it with a heavy layer of gravel all over except for a few low creeping conifers dotted here and there you keep out weeds. if you are on a slope and spray around ( avoiding the conifers) with resolvo, when it rains will the rain wash the resolvo all through the ground and start to kill the conifers. Opinions welcome please. Trying to find out why the conifers are starting to die.

Hi
Did you shield the conifers from the spray? Sprays give off a fine invisible mist that spreads and drifts in the air - years ago I carefully targetted a few dandelions on the lawn ... and ended up with a dead patch a foot across

The active ingredient in Resolva is glyphosate - this takes quite a while for its effect to become apparent - usually up to three weeks - sorry but my money is on weedkiller drift

Resolva starts working very quickly. It's why it's the only one I ever use - when I use it. For dandelions in particular, it's the best, because the others are so slow, you get umpteen at flowering/seeding stage before the weedkiller starts working
It could be animal damage too - you usually mention that Verd

Hello, Sorry I am not able to help, as I am in need of advice too. My conifer is about 50' 40 years old. We laid membrane in the garden and around the tree and covered in bark in 2014. Have just noticed some bark at the ground level has come away, is it a sign of disease, should we have it removed.. ? Hope not .
