Peach tree short life disease (PTSL) kills peach trees in the home orchard after they have grown well for a few years. Just before or after leafing out in spring, the trees collapse and quickly die.
What is PTSL caused by? Read on for information on this problem and tips for preventing the disease. Note that there is no effective peach tree short life treatment for an affected tree.
Peach tree short life disease results from several different stresses on a young tree. Stress factors include external pests like the ring nematode and bacterial canker.
If you want to stop it, though, you should keep in mind that other cultural and environmental stresses can play a role. They can include fluctuating winter temperatures, pruning the wrong time of year, and poor horticultural practices.
You walk out to your peach orchard one morning, excited to see blossoms or fruit, only to find declining trees with bare branches. Your once-healthy peach trees now appear sickly and are dying back. What happened?
Peach trees are unfortunately prone to several issues that can quickly take them from thriving to dying. The good news is that identifying the cause early allows you to take action and potentially revive your trees.
Here are the 7 most common reasons peach trees die and what you can do about them:
1. Peach Tree Short Life
This disease caused by the ring nematode bacterial canker fluctuating winter temperatures, improper pruning, and poor care can result in sudden collapse shortly after leafing out or before leaves emerge in spring.
Solutions:
- Plant resistant varieties like Frost, Madison, and Redskin
- Improve drainage and avoid excessive irrigation
- Prune only during summer to avoid spread of canker
- Remove and destroy infected trees
2. Peach Tree Borer
Larvae of this pest tunnel under the bark and damage tissues that transport nutrients eventually killing the tree. Look for oozing sap, loose bark and frass near the base of trees.
Solutions:
- Use pheromone traps to monitor for adults
- Apply insecticides or nematodes to trunks in spring and late summer
- Scratch away loose bark to reveal and remove borers
3. Armillaria Root Rot
This fungal disease infects the roots and gradually spreads to the trunk, preventing water and nutrient transport. Trees slowly decline and eventually die.
Solutions:
- Improve drainage and reduce irrigation
- Remove infected trees and roots
- Apply fungicides as a preventive measure
4. Peach Leaf Curl
This fungal disease causes leaves to become thickened, curled, and yellowed. It prevents photosynthesis, weakens trees, and reduces fruit production.
Solutions:
- Rake and dispose of fallen leaves
- Apply copper sprays as buds swell in early spring
- Improve air circulation and avoid excess moisture on leaves
5. Verticillium Wilt
Fungal pathogens clog the vascular tissues that transport water and nutrients within the tree, causing wilting, reduced growth, and eventual death.
Solutions:
- Remove and destroy infected trees
- Solarize soil or apply fungicides before replanting
- Graft scions onto resistant rootstock
- Improve drainage
6. Root-Knot Nematodes
These microscopic worms feed on roots and form galls that disrupt nutrient and water uptake. Trees decline gradually and are more prone to other issues.
Solutions:
- Test soil when symptoms appear
- Rotate peaches with non-host crops
- Apply beneficial nematodes
- Graft onto nematode-resistant rootstock
7. Freeze Damage
Early spring freezes can damage buds and flowers, while fall freezes harm roots. This stresses trees and increases susceptibility to diseases and pests.
Solutions:
- Select late flowering, frost-tolerant varieties
- Avoid excessive nitrogen fertilization which delays hardening off
- Protect trunks and roots from freeze damage
A combination of preventative care and prompt treatment of any signs of disease can help extend the relatively short lifespan of your peach trees. Ensure proper site selection, drainage, and nutrition to give your trees the best shot at warding off issues.
With extra diligence, your peach orchard will continue producing that sweet summer harvest year after year. Let your dying trees be a lesson for improving care so you can avoid problems down the line.

Peach Tree Short Life Disease Symptoms
You can be pretty sure that PTSL killed your tree because the trees that get it are usually only 3 to 6 years old. Watch for the leaves to suddenly wilt and the blossoms to collapse.
In addition, the peach tree bark will look water soaked, turn red, and crack. If you cut away some bark and smell it, it has a sour sap odor. In spite of this, the tree’s main root system looks healthy if you were to dig it up.
Once you see these symptoms, expect the tree to die very quickly.

FAQ
What to do if a peach tree is dying?

How do you rejuvenate a peach tree?
What does an overwatered peach tree look like?
Why is my peach tree dying?
Poorly-drained soil is a common culprit for a dying peach tree. Planting in rich, well-draining soil is the best way to ensure a peach tree’s long-term health. When planting a new tree, mix in some compost to help with drainage and to encourage root establishment. Each year, mulch around the tree with compost or other organic material.
Can you lose weight eating peaches?
Peaches by themselves won’t cause you to lose weight, so no, you can’t lose weight by eating peaches. However, peaches are a healthy addition to any diet, and I would recommend them to anyone, unless they’re allergic to them. Not to contradict my previous statement, but peaches could help you lose weight if you replace higher calorie sugary sweets with a peach. Instead of eating a cookie or piece of pie, if you replaced that with a peach, or any piece of fruit, that could help you lower your total caloric intake and lose some weight. Remember, weight loss is impacted by total calories consumed and total calories burned, so the only way to lose weight is to either eat fewer calories or burn more calories. It can be more complex than that, but those are the basics.
Can a peach tree die from over watering?
Generally, peach trees die more often from improper watering and environmental stress, but diseases are still possible. For best results, avoid over-watering peach trees and check their leaves for any spots. Root rot is a fungal disease that most commonly occurs in waterlogged soil. The fungus eats at the tree’s roots, which kills the tree.
Why is my peach tree drooping?
If you’ve recently relocated or repotted your peach tree, and its leaves are drooping or falling off, it’s most likely affected by transplant shock. Peach trees can become stressed from the damage from moving and having to establish a new root system. For best results, avoid damaging the rootball and plant quickly.
Why is my peach tree not growing well?
Here are a few things to look at when first choosing a peach tree, or when figuring out why your tree isn’t growing well. Every peach tree variety needs a specific number of chill hours in order to break dormancy, blossom, and produce fruit.
How do you know if a peach tree is dead?
To see if your peach tree is still alive, prune the tip of a small branch and see if it has any green inside. The best way to find out what’s wrong with peach trees is to use the process of elimination. Check one potential issue at a time and if it seems fine, move onto the next.
