No, they pollenate themselves - unless you have them growing somewhere there are no insects.

MG, I think they were asking if they should feed them.

Wild Bluebells seem to thrive in the woods and grow ok among big trees which will take most of the nutrients for themselves. Is you are growing them in your garden then a bit of general fertilizer now and again won't do any harm.

I wouldn't consider feeding bluebells where ever they were… In the woodland they'll get a good layer of leaf mulch each year Myron. I wonder, given that Jeanette is in the US whether she is referring to a different plant than the one we think of as a 'blue bell', which, by the way, in Scotland tends to mean the hair bell!
