hybrid
hybrid
  • Zaiger family bred and named this hybrid ploutsTM
  • In fact they are plumcots which are ¾ Japanese plum & ¼ Apricot
  • They have the tangy taste of apricots and the high sugar content as well as hairless skin of plums
cold tolerance
Cold Tolerance
  • Japanese plums and plumcots grow well in zones 6 to 9.
  • European plums grow well in zones 5 to 7
  • American plums grow well in zones 3 to 5
production in the us
Production in the US
  • California produces 94%, about 768 million pounds per year.
  • Oregon, Washington, Idaho, & Michigan produce most of the other 6%.
  • Japanese plums make up 55% of total production.
  • European plums make up 45%, which are almost entirely dried into prunes. (99% of the US market)
  • Plumcots & American make up less than 1%.
tree growth limiting factors
Tree growth & limiting factors
  • Small trees that grow 15’ to 20’ tall and wide.
  • Japanese & plumcots grow wider, while European plums grow more upright.
  • They can grow for 20 to 30 years.
  • Japanese & plumcots come into production, 3rd. or 4th. Leaf.
  • European & American come into production, 4th. or 5th. Leaf.
fruiting wood
Fruiting wood
  • Plums bear most fruit on short spurs arising from 2 year old or older wood.
site selection preparation
Site Selection & Preparation
  • Japanese plums & plumcots need sites similar to that for peaches.
  • Few spring frost since they bloom early.
  • 500 – 1000 foot elevations are optimal.
  • Excellent soil drainage if grafted to peach rootstocks.
  • Moderately well drained soil drainage if grafted to plum rootstocks.
site selection preparation1
Site Selection & Preparation
  • European plums need sites similar to apples.
  • Early frost are not a problem because they bloom late.
  • 1500 – 2000 foot elevations are optimal.
  • Moderately well drained soil drainage.
