Why Forsythia Blooms Only Low: Winter Hardiness and Cultivar Selection

Forsythia Bloom Only on Lower Branches

In snowy northeast, flower buds above the snow line are killed by cold wind. Snow insulates lower buds, so they bloom.

Choose cultivars bred for your zone (e.g., 'Northern Gold', 'Meadowlark', 'Vermont Sun').
Plant in a sheltered location.
Mulch heavily to encourage snow cover.

Proper cultivar selection ensures full-plant bloom.
