Growing blackberry

berry / bush fruit

Pollination

Self-fertile.

Growing it

Zones 5-9. Thornless erect types need no trellis; trailing types do. Cut spent floricanes to the ground after fruiting.

Will you get enough chill?

Blackberry needs roughly 200–500 hours between 32 and 45 °F over winter to break dormancy evenly. Check your area with the chill hours calculator. Low-chill breeding has pushed many varieties well below the figure here, so read the plant tag.

Chill and pollination are given at the fruit-type level; specific cultivars can differ. Values are typical ranges for home-garden planning.
