Window Basket Overcrowded?

I think I may have been a bit too ambitious when planting out my window baskets, may have put too much in, everything is doing very well but they are getting a little too big and cramped in there.

Kind of new to this and was wondering if anyone could tell me if i would be doing damage if i tried to remove the Lobelia, which are in between the Fuscia and Geranium or is it best left alone?

 

Hi
Leave a lone water everyday and feed weekly (tomato food) , the lobelia dont last all summer once they have finished flowering you can tidy up then , we all cram them in looks better dripping with flowers rather than one or two now what would you choose but the secret in the watering and feeding follow this simple tip and you will be the envy of the road
