Broccoli and aphids
My broccoli has an EXTREME aphid infestation and although it is very, very bad, they stay on the broccoli (which has gone to bloom) and don't bother my other plants. As gross as the aphids are, my broccoli also houses a very happy, lovely colony of bumble bees, like 60 or seventy! They are so pretty and not aggressive and I can hear them buzzing, as there are so many!! My problem is I don't want the aphids to spread to my other plants on one hand, but on the other, I don't want the bees to leave either. Can I remove the broccoli? Or is it better to just them stay so the bees stay too?? Thanks!
Try neem oil. Not only is it safe to use on plants, but it's an effective treatment against these types of pests. It will eradicate bad bugs but will not harm the good ones, like bees. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
