yellow leaves in summerYellow leaves in fall are heavenly, but yellow leaves in summer? Not so much. If the leaves on your trees are turning yellow, it could mean you have an issue. There are several root causes for yellowing leaves, many easily treated. Before you panic and get out the ax, take a look at some common issues a good tree service can help you manage.

Under Watering

If your tree is not getting enough water, the leaves will turn yellow. Like a camel, your tree will work to conserve water when it’s not getting enough. To do this, it stops sending valuable moisture to the leaves. When this happens, the leaves turn yellow and drop off the tree. Regular watering is important to ensure your tree doesn’t dry out.


If your tree gets too much water, you could see the same result – yellow leaves. A condition called chlorosis occurs when leaves don’t have enough chlorophyll, which is the green pigment in leaves. One reason for chlorosis is a lack of proper iron levels in the soil. Iron is necessary for the leaves to turn that vibrant, dark green hue that makes them so lush and beautiful. Overwatering is one of the primary reasons for this lack of iron and the yellow leaves that go with it.


Pests are another reason your leaves are looking less than green this summer. Like overwatering, certain insect infestations can cause chlorosis. The most common are aphids and pine beetles. Both are treatable if you only have a small amount of the pests. If you have an infestation, your trees will require proper treatment to get rid of the insects and save your trees.


There are many diseases that can turn your trees from lush and green to sparse and yellow. Powdery mildew is one. In the south where the weather is humid, mildew diseases are not uncommon, and they can lead to yellowing tree leaves if left untreated. Powdery mildew starts out looking like dust on your tree leaves but can cause your tree to stop growing and die.


One of the biggest factors in the health of your trees is the environment where they grow. If they don’t get enough light, it can lead to yellowing leaves and slow growth. Unseasonal weather can also impact the health of your trees. If it gets hot early in the season or there’s a lot of rain or not enough rain, those things can shock your trees and cause them to drop leaves as they try to conserve energy.
