Not sure why but our hydrangeas only produce small blue flowers and not very many. Lots of foliage production. We live in Overland Park, KS.

Welcome!

It could be:

not enough sun

not enough fertilizer

or maybe improper pruning.

What kind of hydrangeas are they? Have they always performed this way? Can we see a picture?

If it is a mophead or lacecap, it may need winter protection to reliably bloom in Kansas Zones 5-6. The mophead/lacecap hydrangeas that produce flower buds only on old wood may suffer from stem dieback during cold winters... so you end with no blooms or just a few. You can usually tell stem dieback has happened when the stems from the prior year do not leaf out and all growth (or most of it) originates from the crown,
