Castleton is a modern dual-purpose early-season plum. It was developed for the New York commercial plum-growing market, and these qualities also make it a good choice for the backyard orchard.

Castleton can be eaten fresh when fully ripe or used in the kitchen if picked slightly earlier. It is a freestone plum - the stone falls away from the flesh easily.

How to grow

Castleton will readily over-crop, and it is important to make sure a strong branch framework is developed in the first few years before you allow the tree to set fruit.

Historical details

Castleton was developed at the New York State Agricultural Experiment Station, part of Cornell University, under a team led by John Watson, and released in the 1990s. Castleton is a cross between Valor and Iroquois.
