I don't like to particularly use pesticides.
What are some good tips to keep insects away from my marigolds?
There are some bugs that love marigolds, earwigs eat them up! An easy, effective and cheap way I have used is beer bait. Pour some cheap beer into a shallow dish, (actually empty, clean tuna cans work the best) and put near the plant that the bugs are eating. The next morning, there will be all sorts of dead bugs in the dish. Dump it out, clean it and put more beer in! Works every time!
Reply:Every time I have ever tried to grow marigolds they have been half eaten by bugs. I said I would never plant them again but I had some given to me this year so I tried again. I was spraying my roses with ortho spray for fungus and bugs and figured what the heck, it can't hurt so I sprayed my marigolds. They are beautiful and bushy, the prettiest I have ever had and no bugs on them at all.
Reply:spray soapy water on them. (use liquid detergent like Palmolive). I don't remember the proportions, but I think it's a teaspoon of detergent in a regular spray bottle full of water. Bugs hate the smell of the detergent
Reply:Marigolds are naturally an insect repellent. They have their own chemical defense systems.
