Plums and Prunes آلو و آلوچه
Seasonal activities: Winter
(mid December through mid March)
- If San Jose scale, mites, or aphids have been problems in previous growing seasons, spray the tree with dormant oil late in the dormant season, just prior to bud break. Oil sprays applied late in the dormant season are least likely to cause shoot injury. Be sure to provide thorough coverage of the tree, including the trunk.
- On mature trees, prune out any dead, diseased, or broken branches. Thin branches out (usually 20% of last year’s growth) to allow good light penetration into the tree. The purpose of thinning cuts is to reduce crop load and increase light penetration. Do not make heading cuts that shorten the tips of the shoots.
Problems and Opportunities
- Priority problems and opportunities for plums are not yet confirmed.
- Most plums need to be cross-pollinated to set adequate crops, so two different varieties should be planted.
