The best thing you can do for Bees and pollinators is not use any systemic pesticides or fungicides.
Any item sold to last all season, weed n feed, rose fungicides, any long term protectant is going to effect your bees!!
Don't buy any plants that are raised with them.
A bit harder because nurseries are rarely organic.
If it looks perfect it has pesticides on it.
Buy Local. Ask questions.
