non-blooming hydrangeas?

I bought a house in Stratford, CT 3 years ago. There are a number of hydrangeas that the previous homeowner planted. 3 or 4 bloom beautifully every year, but another 3 or 4 (in the same basic location - south east side of the house - mostly sunny) have never bloomed. Any idea why a few a prolific bloomers and the others don't as much as sprout a bud? Thanks!

Hi,

 

Thanks for writing. Some common reasons why hydrangeas don't bloom are:

They get too much shade

They're pruned at the wrong time of year

Especially cold winter temperatures kill their flower buds

Their flower buds get zapped by a late-spring frost

They get too much fertilizer (and respond by putting all of their growth to leaves instead of blooms)

 

Do any of these sound like they might be a possibility? Keep in mind that different varieties have differing hardiness levels and light needs.
