Growing serviceberry (juneberry)
pome fruit
WINTER CHILL NEEDED
~400–1000 hrs
POLLINATION
Partly self-fertile — crops much better with a partner
Pollination
Sets some fruit alone; a second seedling or variety improves the crop.
Growing it
Zones 2-7. A tough native small tree or shrub with blueberry-almond-flavoured fruit in early summer. Watch for cedar-serviceberry rust near junipers.
Will you get enough chill?
Serviceberry (Juneberry) needs roughly 400–1000 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.
