Chicago Hydrangea Bloom Failure: Frost and Variety Solution

Why They Don't Bloom

Traditional hydrangeas bloom on old wood. Warm spring spell → bud swell → frost → bud death. Foliage grows, no flowers.

Solution: Reblooming Varieties

Plant Endless Summer, Penny Mac, Mini Penny, Dooley, or Blushing Bride. These bloom on old AND new wood—flowers even if spring buds killed.

Relocate Old Varieties

Move to north side of house. Ground stays cold longer → later bud swell → past frost danger.
