Cannas Looking Ugly
I have some cannas in my front yard. I'm thinking of cutting them all the way to the ground because they look bad, pests ruined them. I am hoping next year they come back. Would it be ok to spray the cannas once a week to keep bugs away with pesticide?

You can cut down the flower stem as far as you like, but make sure to leave the foliage as the plant needs this to store energy for next year's flower. You can spray the plants with neem oil, per directions, for pests.
