Summer is a season of vibrant blooms, lush greenery, and bountiful harvests. But along with the joys of gardening come the challenges of combating plant diseases that can wreak havoc on our beloved plants. Many professionals with excellent gardening read and keep learning how to identify and combat these diseases. So you should do that, too, no matter your level.
As temperatures rise and humidity increases, certain diseases become more prevalent in our gardens. Don’t fret, though. Let’s explore some common summer plant diseases and provide you with effective strategies to keep your plants healthy and thriving all season long.
Powdery Mildew
Powdery mildew, that powdery white coating we often find on leaves and stems, is a common fungal disease which can affect a wide range of plants during the summer months. This pesky fungus thrives in warm, humid conditions and spreads rapidly if left unchecked. You can tell it’s powdery mildew from its white or grayish patches on plant surfaces. Infected leaves may also become distorted or stunted, leading to reduced growth and overall plant vigor.
To combat powdery mildew, creating an environment that is less favorable for its growth is crucial. Start by ensuring proper air circulation around your plants by spacing them adequately apart. Pruning any overcrowded branches can also help improve airflow within the canopy. You can also use organic fungicides specifically formulated for powdery mildew control as part of your prevention routine.
Aster Yellows
Aster Yellows is a common plant disease that can also wreak havoc on your summer garden. Caused by the aster yellows phytoplasma, a type of bacteria-like organism, this disease affects an array of plants, including asters, marigolds, and petunias. It’s characterized by the appearance of yellowing or discolored leaves. These leaves may also become distorted or stunted in growth. In some cases, you may notice abnormal flower development as well.
The spread of Aster Yellows can be attributed to leafhoppers, tiny insects that feed on infected plants and then transmit the disease to healthy ones. Sadly, no effective chemical treatments have been found for this disease once it has taken hold in your garden. But you can always prevent it from spreading by practicing good sanitation by removing weeds and debris can help reduce the chances of infection.
Summer Patch

The first sign of summer patches is usually yellow or brown patches on the lawn, which can quickly spread and become larger over time. To combat Summer Patch, boost the overall health and vigor of your grass. It can be done by mowing at the proper height for your type of grass, watering deeply but infrequently, and fertilizing regularly with high-quality lawn fertilizer. Additionally, aerating your lawn can help improve drainage and reduce moisture levels contributing to fungal growth.
