Problem with Dahlias

BILLYCBILLYC Posts: 70
I've overwintered dahlias for the past eight years or so in pots. In the spring I repot the tubers using multipurpose compost and a spoonful of Growmore. Every year they have been reasonably successful in flower growth.

This year I added a handful of chicken manure pellets to each pot (32 pots). The leaves have grown like wildfire but there are no sign of buds or flowers. It's obvious, even to me a complete novice, that the chicken manure has added too much nitrogen, so the leaves are developing at the expense of flowers.

Is there any way I can encourage these plants to produce buds? I thought of adding Tomorite to each pot which I believe encourages flower growth? But, this too contains nitrogen, so am I just compounding the error?

Desperate for help!

    it is quite early for there to be flower buds yet.
    Tomorite once a week would increase the potassium and help formation of flowers.
