Does anyone know what and when to spray for leaf miners on Korean box?

I didn't even know boxwood ever got leaf miners.  Of course, they are not a common plant here in the north, even though big box stores sell tons of them.  :rolleyes: 

Welcome to the forum, Alice.  And thanks for the link.  Many years ago, our U of Minnesota had a hort hot line, but they became so inundated with calls that they were forced to begin charging a fee.  We still have the county extensions and other free resources, though.
