Peach Tree Leaves Turning Yellow – What To Do

Peach trees are grown for their fruit in orchards and enjoyed by people worldwide for their exquisite taste. The fruit is difficult to cultivate unless you live in the right areas. On top of this, the tree-like many other fruiting plants have their own set of problems.

Growers of peach trees often ask, why are my peach tree leaves turning yellow? The yellowing of the baby peach tree leaves the most typical problem. Most often, such issues are caused by overwatering or underwatering. You can also see peach tree leaves turning red occasionally, although a peach tree with yellow leaves is the issue you need to deal with the most.

Another reason can be an iron deficiency, which causes your peach tree leaves to turn yellow with green veins. Aside from this, the peach tree’s leaves turn yellow because of fungus infections. Finally, aphids can cause fully grown trees to turn yellow.

While you can get fungi-resistant peach trees, there are enough other issues that can cause your peach tree leaves to turn yellow. Understanding the symptoms and causes is far better, and then you can fix these using alternative solutions.

What Do I Do When My Peach Tree Leaves Turn Yellow?

Before dealing with your peach tree yellow leaves, you must first understand the first sign of the problem. Therefore we have a list of common issues that won’t let your peach tree buds swell. Next, you should have contrasting colors of pink and the bright green foliage showing a healthy tree.

Let’s look at the reasons for this:


Chloris is only found in peach trees when iron is scarce in the soil. Because iron is required to create chlorophyll, a lack of iron compromises a peach tree’s ability to perform photosynthesis.

As a result, the tree’s leaves turn yellow around the edges. To help the soil retain nutrients for optimal Peach tree feeding, keep the soil’s pH below 7.5 so the trees can easily absorb the newly available iron.

Fix: Add iron sulfate to the soil to lower the pH, allowing your tree roots instant access to newly accessible iron. Use a pH meter and maintain a balanced soil pH.


Scale can often be mistaken for a pathogen but is a small insect living on the leaves and stems of peach trees.

They steal necessary plant liquids from the leaf by piercing it with its sharp mouths. The leaves cannot accomplish photosynthesis because the scale removes many vital liquids (including chlorophyll). Yellowing of the leaves occurs because of these factors.

Fix: To prevent scale in peach trees, apply horticultural oils to the leaves during the dormant season. You can also use insecticides to combat scale. Although, you can’t use these while your peach trees are in blossom. The reason for this is that insecticides can hamper the natural pollination process. In addition, such contributing chemicals add to future edible fruits and also affect the pollinators. (Learn How To Grow An Avocado Tree That Bears Fruit)

A copper-based fungicide may have a lower impact, yet it can be better to try implementing alternative solutions in the growing season. If you need to spray, do so in the fall or the spring after the buds swell.

How Do You Fix Yellow Leaves On Fruit Trees?

Weed control is critical for producing large, tasty sweet fruit peach trees. Weed roots battle for water with peach tree roots. When a peach tree concentrates its efforts on producing and maturing fruit, it requires a consistent water supply.

Apply a thick layer of mulch around the fruit tree to preserve moisture and keep weeds at bay. Mulch 3 to 6 inches away from the trunk to the drip line, where the branches end. Mulch should not be applied directly to the tree trunk since moisture can apply disease to the tree’s bark.

Peach Leaf curl cause by Fungus

Why Are My Fruit Tree Leaves Turning Yellow?

Peach Leaf Curl

Peach Leaf curl is a term for the fungus called leaf curl to describe yellowing from the Taphrina deformans fungus. The foliage often goes from green to red to yellow leaves as the fungus spreads within the leaf structures.

Fix: To prevent Peach leaf curl, spray with a fungicide. Apply the fungicide after the peach tree’s leaves have fallen off late fall or early winter. It will protect the trees from peach leaf curl during their dormant season.

If the fruit tree is in a wet winter period area, a fungicide can be applied again near the end of the season to prevent Peach leaf curl across the dormant period.

Root and Crown Rot caused by Phytophthora

It isn’t merely a peach tree that is susceptible to this disease; most stone fruits are susceptible. Most often, trees die within weeks or months of exhibiting the first signs of disease in the deep green foliage of your peach trees (Prunus persica).

However, the reduction is gradual in certain circumstances and occurs across several growing seasons.

Trees infected with this exhibit stunted shoot growth and sparse, yellow, and small leaves. Fruits will be burned, small, and other crown rot symptoms include dark decaying areas near the soil line on the root crown and trunk base.

Fix: The bad news is that this problem has no chemical solution. The most effective control technique is careful water management. Select a well-drained planting place for your trees’ shallow raised beds.

How Often Does A Peach Tree Need To Be Watered?

If the plant is subjected to drought, the peach leaves become yellow and fall off like leaf curl. Then, the peach tree leaves will grow dry and crisp and turn yellow.

During the heat, the peach tree needs a lot of water. So in the summer, water your Peach tree every other day to keep it hydrated. Only do this if the tree grows on bare soil with no additives.

You can water the tree once every two or three days if a 2-3 inch layer of mulch surrounds it. When you do so, water deeply to at least 2 feet deep. A metal rod or stick can help determine the water level’s depth.

However, over-watering promotes yellowing of the foliage, and your peach tree’s leaves will turn yellow if you over-water it. The leaves of an over-watered tree get drooping and become yellow to red to purple.

Because of this, peach trees should not be watered excessively as over-watering causes the soil to become soggy. (Learn How To Kill A Tree Without Cutting It Down)

In such wet conditions, you can find issues with peaches and other trees as leaves yellow. Finally, leaves fall and are ripe for fungal disease as the fungus grows in moist conditions.

Waterlogged conditions cause root rot; if you don’t act, root rot can damage or kill your peach tree.

When over-watered, the leaves of the peach tree droop and yellow, although they feel fine to the touch. If you have an under-watered tree, the leaves may yellow and feel completely dry.

Soggy soil will surround your plant, so feel around your tree with your fingers for a more accurate diagnosis. You can also use a moisture meter to get such a reading.

If you are in the warm weather of summer, water your peach tree three times a week. To avoid frequent watering, water the tree deeply when you do.

If the tree is surrounded by mulch or close to the rainy season, water the plant less frequently, but ensure the tree has water down at the root ball level.

If you check with your fingers, if it is dry below the top two inches, you’ll need to water before your leaves yellow. (Read Browning Avocado Leaves Guide)

Over-Watered Peach tree

If your peach tree has been over-watered for a week or two, don’t water your peach tree.

If the soil is heavy or clay, add compost to improve the drainage and aeration of the soil.

Examine the roots to discover if they have been afflicted with root rot. If they are, seek advice from local horticulturists.

Newly planted trees require 5 to 10 gallons of water each week in hot weather. However, when it’s a hot summer day, fully grown trees require roughly 15 to 20 gallons daily.

Fix: Water your plants with daily drip irrigation or once every 1 to 3 weeks using a sprinkler. However, this depends on the temperatures, soil type, and the stage of the growing season you are at.
