3 Tree and Shrub Diseases To Watch For Heading Into Spring

how to treat leaf spot diseaseYour trees and shrubs play a vital role in the beauty of your lawn and landscape. Not only do they enhance the appearance, but they also bring a sense of order and structure to your home and garden. You’ve invested your hard earned time and money into your trees and shrubs over the years, and protecting them is of utmost importance to you.

 

As the weather continues to warm up, and we inch closer to spring, your trees and shrubs may be at risk to some possible “pre-spring” diseases. Here are 3 of the more common diseases that you will want to watch for as we head into the growing season:

 

Leaf Spot

Leaf spot is one of the most common spring diseases found on the leaves of trees. An over-wintering fungus that is spread following the first spring rain causes it. The cool, wet weather during the early spring months provides favorable conditions for leaf spot to sustain and spread.

 

As the fungus grows, brown and black blotches will appear on the leaves. Even in the worst-case scenario, it will not result in the death of the tree. However, leaf spot will affect the appearance of the trees in your landscape, so it’s definitely something you’ll want to keep an eye out for over these next few months.

Very similar to leaf spot, needle cast is a disease that affects spruce trees and is caused by the fungal pathogen Rhizosphaera. This disease enters and overwinters in fallen needles. As the early spring rain comes, the spores are spread via the splashing rainwater. More often than not, the needles most vulnerable to needle cast are on the bottom half of the spruce tree.

 

If the needles on your spruce tree turn red, then brown, that is the initial sign of needle cast. If they fall to the ground in small groups of 12 or more, that is a telltale sign that your tree is infected and preventative measures will need to be taken.

 

Powdery Mildew

This disease affects the shrubs in your landscape. Living up to its name, it is a white, powdery fungus that spreads quickly on the leaves of your shrubs. It will steal essential nutrients from the shrub and as a result, it will significantly slow the plant’s production process. Powdery mildew also makes the plant weaker and more susceptible to other diseases.

 

Unlike most diseases, powdery mildew can thrive in most climates (wet, dry, hot, cold, etc…). You’ll want to keep an eye out for the white, flour looking substance on the leaves of your shrubs in the spring, summer, and fall.
