NY9 Plum TreeThe NY9 plum tree, also known as Kenmore, is a European-type plum developed by Cornell University in 2009. This variety is a cross between Stanley and Standard, and it is highly regarded for a number of reasons. The NY9 plum tree is self-fertile and extremely productive, capable of producing abundant crops even in less-than-ideal conditions. Due to their disease resistance, they are less susceptible to common plum ailments such as black knot and brown rot. In early September, these plums ripen and have a mild, sweet flavor. They can be eaten fresh, canned, baked, and used in other culinary preparations. A versatile and attractive choice for orchards and gardens, these hardy, vigorous trees reach 20-25 feet in height and thrive in USDA zones 5-8.
- Hardiness Zones: 5-8
- Pollination: Self Fertile
- Harvest Period: Early September
- Disease resistance: Good

- how well the rootstock adapts to your soil
- the disease pressure on your site
- how well the rootstock anchors
- precocity (bearing fruit at a younger age)
