What are Purple Leaf Plum Tree Problems?

Nobody wants to hear that the lovely purple leaf plum tree in their yard could be a host to many problems.

Luckily for you, this tree is quite hardy. Even so, when it does not receive the proper care, it can suffer.

The main problems a purple leaf plum tree has is that it is susceptible to diseases. These diseases include leaf curl, powdery mildew, cankers, leaf spot, root rot, prunus ringspot and black knot.

Fungal Diseases

Lots of plums on a treeYour tree can develop cankers, mildew, or even galls. Cankers are the most common, and these can injure the tree’s woody parts, forcing it to produce a gum.

Galls are also a threat to the plant, more so the black knot galls. These disfigure the tree, and if not dealt with timely, they continue doing so and can kill it completely.

Let’s not forget about the mildew caused by the Podosphaera Oxyacanthae pathogen often seen in winter. It paves the way for mildew which makes a home on leaf surfaces, leaving behind a residue.

You may be wondering, ‘how can you stop all these fungal diseases in their tracks?’ Let’s do it one by one. To get rid of canker, you cannot rely on chemical means.

Instead, you must get rid of all the infected wood and bark through pruning. Once you get to the clean wood, you can focus on saving your plant.

For black knot, you can always use fungicides with lime sulfur or Bordeaux in their mixes. Finally, for the mildew, you can use a fungicide.

How about preventing fungal diseases? One way is by avoiding overwatering the tree. Also, ensure it has enough air circulation by not planting too many trees in the same section.

If you can control the water and air components, you will be one step closer to eliminating fungal problems.

Bacterial Diseases

With purple leaf plum trees, you deal with leaf spots and shothole diseases. These look similar, and telling them apart can be difficult.

They start by appearing as spots on the leaves. These spots then enlarge from the center and then become holes in the leaves.

The more of these spots that turn into holes, the harder it is for the plant to make food, and its leaves start yellowing and falling off.

Can you treat bacterial infections? These are not easy to ward off with chemicals. However, you can control their spread with some bactericides.

Your best bet lies in controlling the cause of the infection. Most people who face such infections have overfertilized their soil. It’s better to give your soil less nitrogen than to provide it with so much that the plant turns on itself.

Viral Diseases

Finally, you also need to consider the possibility of viral infections, especially the Prunus ringspot virus that affects almost all plum varieties.

It shows in the form of spots, rings, and other changes in leaf patterns. As the disease progresses, you may notice that the tree’s growth has slowed. Luckily, this infection is not as severe as a fungal one and rarely kills trees.

Is there a cure for viruses? No. Instead, the only way to deal with the problem is by controlling it.

You need to avoid overfertilizing the soil or giving it too much water. As you deal with the causes, you will notice that the tree will start looking better.

So, the signs that your tree is not doing well are:

  • Spots, rings, and pattern changes on the leaves,
  • Yellowing of leaves,
  • Residue on the leaves,
  • Stunted growth,
  • Falling of immature leaves, and
  • Disfigured tree growth.

Have you seen any of these telling signs in your tree?

  • Newport: This variety boasts deep purple leaves in the summer, which turn reddish-purple when fall comes.
  • Nigra: This tree has dark purple leaves in the summer, which are orange-red in the fall. How interesting is that?
  • Purple Pony: This tree is the dwarf version of the rest and reaches about 12 feet tall on average. Widthwise, it gets to about 10 to 12 feet.
  • Thundercloud: This plant features reddish-purple leaves like the Newport does in the fall.
  • Krauter Vesuvius: What an interesting name! Its changes are as exciting, with dark purple leaves as it moves from spring to the fall.

Your tree will generally require:

  • 6 or more hours of sun: This exposure should be adequate to allow the foliage to make food and allow the tree to dry and air out to avoid fungal growth.
  • Well-draining soil: The plant should never be in the water for too long as it can trigger the fungal diseases earlier discussed.
  • A soil pH of 6-8: The tree does best in neutral or near-neutral soil pH and will thrive better in such conditions.
  • Medium watering: This hardy tree is moderately drought resistant and can go a while without water. You are better off underwatering it than you are overwatering it.
  • Fertilizing 4 times a year: The tree should get fed four times a year using all-purpose food in ratios 7-4-4.
