The Q&A Archives: Fruitless fruit tree

Question: 18 months ago I bought a Pullot tree. The name on the tag says Citation Hybrid Rootstock. So far I have had no fruit. Why, do I need a second tree to pollinate it? The vendor told me I did not need a 2nd. tree.
Thank you, Bill

Answer: A Pluot tree is actually a trademark of the Plumcot, a cross of the apricot and plum. Both names are now often used interchangeably. Both the apricot and plum are in the prunus family and they have been hybridized to set fruit with the best qualities of both fruits. You can grow these trees in your own garden just as easily as you can the plum or the apricot.

Most Pluots have a minimum requirement of from 500 to 800 hours of chilling. Chilling is the dormant rest requirement for a tree to set fruit successfully. There are a number of different ways to calculate this, the simplest being to figure an hour of chilling for every hour of temperatures under 45'F during the autumn and winter months.

If your tree is not getting the winter chill it needs, it won't flower and set fruit. Check the tree next spring to see if it flowers for you. If not, there will be no fruit. If it does flower but does not set fruit, it isn't being pollinated by insects. You can attract pollinating insects to your garden by planting things that flower at the same time as your pluot tree. Hope this information helps!
