Growing plum (european)
stone fruit
WINTER CHILL NEEDED
~700–1100 hrs
POLLINATION
Self-fertile — one plant crops on its own
Pollination
Most (prune plums, 'Stanley', greengages) are self-fertile.
Growing it
Zones 4-8. Firmer, sweeter, later than Japanese plums; the drying types are the true prunes.
Will you get enough chill?
Plum (European) needs roughly 700–1100 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.
