In this post, Clark Tree Experts, your leading tree service specialist in Gainesville, GA, explains more about this leaf-color phenomenon.

Is This Leaf Yellowing Normal?

When you plant a tree, do you learn everything possible about it? Is its leaf color supposed to change? Will the tree turn yellow during the fall? 

Some species have naturally pale green to yellow leaves all year round. If yellowing happens out of the norm, something is wrong.

Why Have My Tree’s Leaves Turned Yellow? 

Finding the exact cause can be difficult. When a tree’s leaves start to turn yellow, look at the following factors:

Insects

Some insects love nothing more than to suck on juicy green leaves. Common examples are aphids, caterpillars, and spider mites. 

Diseases

Bacteria and fungi also interfere with the tree’s ability to photosynthesize. With a tree’s system producing less green color, the leaves will turn yellow.

Pests

Rodents and other pests can gnaw on roots. This damage reduces the tree’s ability to absorb water and nutrients, causing yellowing leaves.

Bad Irrigation

Watering too much or too little can cause leaves to turn yellow. In both cases, the leaves are likely to be limp. Too little water stunts the leaves or they curl up to reduce the surface area from which moisture can evaporate.

Mineral Deficiencies

Why are my tree leaves turning yellow? Commonly, leaf chlorosis results from mineral shortages, diagnosed by having soil tested to find out what nutrients your tree lacks.

Too Much Sunshine or Shade

Too much sunshine scorches the leaves, but too little inhibits photosynthesis. If the tree’s young enough, you could transplant it to a more suitable spot. If you can’t do that, erect a shade cloth or prune surrounding trees to let in more light.

Herbicide Damage

If you have been using a weed killer, these products may kill any plant it lands on. While it will take a long while to kill a full-grown tree, the spray might damage the leaves and turn them yellow, so be very careful when applying it. Sometimes, it’s better to use a liquid rather than a spray formulation.

High Temperatures

Your tree wilts in the Georgia heat just like you do. This is where you’ll notice the leaves starting to furl up and turn yellow. In this case, it would be a sign that the tree is overheating or not getting enough water.

Drought

In a drought, you’ll notice the same signs as with high temperatures but with more intensity. Your tree will go into survival mode, cutting off its extra foliage to retain its resources. There’s not much you can do if there are water restrictions in place in your area, but thankfully, older indigenous trees usually come through with flying colors.

There Is Such a Thing as Summer Dormancy

Dormancy is common in winter, but some trees have made a natural evolution to protect themselves and go dormant during the hotter months. Even trees that are not technically deciduous may shed their leaves if it gets too hot and dry or as a result of heat stress. This dormancy period ends when the rainfall returns to normal.

If summer dormancy happens, there’s not much you can do to reverse the process. However, you can see if you need to augment the watering schedule for next year.
