I use Repel on my daylilys..it is in a bottle bought at Lowe's stores..
It is a spray that has garlic etc in it.
I spray just a few of my perennials in a flower bed or every 4th plant
to save money and s pray..
You might be able to spray each tree an area the size of a saucer
and do this once every week..
It works and has for 10 years here for me..none of my flowers have been nibbled on
if the spray is on some of the plants and applied after a heavy rain and or applied
once every 7 days..small area sprayed..
