Plum Trees - AU Rubrum

Prunus salicina
USDA Hardiness Zones: 6-8


The AU Rubrum plum tree produces fruit that is ideal for canning, preserving and fresh eating. This plum produces very large abundant crops of delicious, sweet, and juicy plums. These plums have a sweet red flesh and very dark red skin and is generally clingstone. Trees of AU Rubrum are spreading with dark green leaves. In test orchards in Alabama, the trees were vigorous, disease resistant, and long lived. The plant is self fertile, but will produce much better when pollinated with another AU or the Methley plum; flowers profusely, and sets a heavy crop. The cultivar has proved its ability to produce high yields of excellent quality fruit where certain fruit and tree disease problems occur. It is an early maturing cultivar that produces fruit of excellent size and quality. Ripens mid-late June.  Developed at Auburn University.

How to Plant
STEP 1) First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need.
STEP 2) Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting.
STEP 3) Remove the plant from the pot and place the root ball in the hole. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system.
STEP 4) Once the plant is in place, backfill the hole with native soil and any leftover potting material.
STEP 5) Pack down the soil to eliminate any air pockets.
STEP 6) When finished, water thoroughly.
Care Guide

To encourage a vigorous and high yielding plum tree, thin the tree's fruit in May and again in July, removing the damaged and diseased fruit so that the rest have room to grow. Prune plum trees in the winter. Regularly remove suckers from around the base of the tree.
