Whether grown in the home orchard or the edible landscape, plum trees are a joy to grow and harvest. The sun-ripened, sweet fruits are wonderful for eating fresh, dried or made into recipes. Plums, along with plumcots, nectarines and peaches, are stone fruits. Plum trees perform best when they are planted in a location that receives at least six hours of direct sunlight daily. When buying a plum tree for sale, make sure it will grow in your hardiness zone. Next, consider the tree's mature height and spread. Dwarf plum trees are often good options for gardeners with limited space. Other factors to consider are the harvest time and flavor of the fruits.
