I have a Flavor Supreme pluot. The year before last it had a lot of fruit. I do not have a pollinator for it, but the neighbor's have a plum. Last year it had only a few fruits. I want to get a pollinator. According to what I read it needs to be another pluot or a plum (there is a list of them). Why can't it be an apricot?
Pluots, like plums, will also need a pollinizer of a different variety to ensure good fruit set. Most pluot varieties will pollinize another pluot variety. Another option is planting certain varieties of plum to pollinize the pluot. Plant a Japanese plum tree within 100 feet of the pluot for cross-pollination. Although a pluot is part apricot, another apricot will not serve as a pollinator.
The most common reasons for non-productive fruit trees are less than 6 hours sunlight daily (more is better) and pruning, which may be excessive and/or which may remove the fruiting wood. Beyond that, it’s important that your fruit trees are irrigated throughout our dry months; the general recommendation is at least once a week, applying adequate water to penetrate 8 to 10 inches deep. Pluots do not grow in alkaline soil, and they require adequate drainage.
