Plum trees are vulnerable to a variety of diseases and pests. In some cases, you can treat the problem with a fungicide or pesticide. However, if you have an infestation of plum tree borers or other pests, you may need to prune the tree to reduce its size and make it less attractive to the insects. If you see signs of disease in your plum tree, such as yellowing leaves or brown spots on the bark, there are several steps you can take. These treatments will help keep your tree healthy and thriving while preventing further damage from occurring.
Fungus is a common problem for plum trees, but it’s easy to treat. The first thing you’ll need to do is identify the type of fungus you’re dealing with. Black knot and brown rot have similar symptoms, but black knot has more of a knotted appearance, and brown rot has an irregularly shaped appearance.
If you think your tree has black knot, then you’ll want to prune out any affected branches and dispose of them properly so they don’t spread the disease. You should also prune out any damaged or dead branches as well. Once your tree is healthy again, make sure that you plant it in an area that gets good drainage and full sun exposure you can’t grow plums in shade. You should also water regularly during dry spells so that your tree doesn’t get stressed out by too much sun or lack of water.
- Prune the tree. The first step to treating your plum tree should be pruning it, both to remove any dead or infected branches and to promote new growth. Pruning will also help you identify which branches are infected by fungus because they will look different than healthy parts of the tree.
- Spray the tree with fungicide. When you’re ready to take further action against fungus on your plum trees, spray them with a fungicide made specifically for fruit trees—not all pesticides work equally well against this type of infestation. Be sure that whatever product you choose contains copper sulfate, lime sulfur, or both; these chemicals can kill off fungal spores before they have a chance to spread through other parts of your garden (or infect other plants).
- Wash away spores with vinegar. If chemical treatments aren’t working for you, try spraying down affected areas with vinegar instead; this acidic substance is effective at removing fungal spores from plant leaves so that they cannot spread elsewhere during windy weather conditions such as strong winds or storms that might carry them around town where other plants may become infected too.*
Inspect the Tree
In order to treat fungus on plum tree, you must first understand the type of fungus present. The most common types include:
- Powdery mildew
- Leaf spot
- Rust (brown spots or lesions)
Causes Of Fungus On Plum Tree
A plum tree can become infected by a fungus at any time during its life. Fungus typically attacks trees that have been weakened by other factors such as poor drainage, overwatering, poor air circulation, too much shade, and too much sun.
Poor soil conditions also contribute to the spread of fungus on plum tree. Fungus spores are carried in the wind or by water droplets from nearby plants or other sources of moisture like rainwater or dew droplets on fallen leaves that splash onto young buds during spring showers. If you notice your plum tree is developing brown spots on leaves or twigs then it’s likely that there are fungal spores present which may lead to further leaf drops if left untreated.
How To Care For Plum Tree
- Prune your plum tree to encourage healthy growth.
- Fertilize the soil around the roots of your tree, doing so in early spring and again in late summer.
- Water your plum tree regularly and deeply (at least once a week), especially during hot weather.
- Protect against pests by placing netting over the top of the tree or by spraying chemicals on it—but be aware that pest control chemicals may be harmful to you.
- Prevent excessive heat from reaching your plum trees by watering them every few days if there’s been no rainfall since they were planted, or if they’re exposed to full sun for long periods of time
How To Prevent Fungus On Plum Tree
Fungus on plum trees is not a problem that should be taken lightly. It can be dangerous for your plum tree, and if left untreated it can spread to other trees in your yard. The best way to prevent fungus on plum trees is by making sure you are keeping them well watered, well pruned, well-fertilized, and well mulched. By doing so you will keep the environment around your tree healthy and happy.
Treatment Of Fungus On Plum Tree
You can treat plum tree fungus with fungicide. Fungicides are chemicals that kill or prevent the growth of fungi. You can purchase fungicides at most garden supply stores, or ask your local nursery for recommendations. Don’t apply a fungicide too often, as it may burn the leaves of your plum tree. Apply the product according to its labeled instructions, and only when necessary—don’t use it just because you’re afraid of disease affecting your plum tree.
