There are several plants that the flowers are starting to decline and only have a few blossoms left but the bees and pollinator's are still visiting them a lot. Should I wait to trim them down? I don't know what the two bugs on the bottom picture are, pollinator's or enemy.
2ofUs, if you have a bug on the flower, it is not an enemy, but a pollinator. If the insects are still visiting the declining flowers, leave the blossoms until they are completely done. You're doing a good thing--providing pollen and nectar for pollinators.
I agree with @marlingardener In the second photo, the top bug looks like a very small bee of some sort. One of the native bees. Good thing to encourage. The green bug? I don't know. Is it too big to be an aphid? I don't see any evidence of bug damage though. BTW, good for you for deadheading. It is something I do sporadically & not often enough.
2OF--it is not clear to me if you are talking about dead-heading or cutting the plants off far down the stems.
Sjoerd, I only cut the dead blossoms off unless it is a spike of flowers, then I just cut the spike off. I leave as much foliage as I can. I know that you can cut some WAY back but I don't know which ones and I think the leaves feed the plant. I grow a lot of different varieties of flowers but treat them all the same.
I see what you mean, 2OF. When I "deadhead" my flowers I deadhead them when they are closed and completely finished. Good luck with yours and let me know how it went.
