Polyanthus not flowering

[divvy]

My poly's and pansies were in flower when I planted them. I have picked off the dead flowers to encourage more but they are not playing the game. Some look healthy some look a bit sparse with not many leaves. They are in good compost, I have tried watering them with tomato food to get them to flower again. I think if I water them with something like miricle grow they will be all leaves and no flower , which is what some of them are like already. Any ideas anyyone .

Mine ahve stopped flowering. They're really spring flowers. People who have them as spring bedding will now be replaceing them with summer stuff. They'll flower again next spring, if it's any help?

Mine at the house have just about had it now. Can't complain though as they have given a wonderful show for the last couple of months.
I'll dig em up and place them in a clump somewhere (probably at lottie) and decide in the autumn whether to split them, replant them as they are, or leave them at lottie for a bit of winter colour.
