Would Creeping Myrtle Like Unbrewed Coffee?
I have some stale coffee in mostly unused containers. Would creeping myrtle or forsythia do well with it?

Occasional use of brewed coffee is ok for these trees/shrubs, but regular use will cause the soil to become too acidic for any plant. You can use unbrewed coffee in your garden much the same way as you would the brewed without adding too much acidity to your soil, which in many cases isn't much higher in acidity than anyway.
